INTENDED FUNCTION

The intended function of the AV-300/350 is to provide reception of weather and other data products that will assist the flight crew in assessing whether current conditions are suitable to the flight characteristics of their aircraft. The AV-300/350 weather data is NOT to be used for tactical weather maneuvering. The AV-300/350 weather data is intended to supplement weather data received from Flight Service Stations and Air Traffic Control, and will improve the pilot’s overall situational awareness.

The AV-300/350 Broadcast Datalink Receiver is an aircraft Flight Information Services – Broadcast (FIS-B) receiver that meets the requirements of TSO-C157. Additional related features in the form of broadcast audio content are also made available.

RADIO ACTIVATION

The AV-300/350 must be activated with WSI to enable the reception of weather data. If the AV-350 is audio-enabled, the Sirius Radio preview channel will be available prior to activation, and will be automatically tuned after the AV-350 receiver has completed its initialization. The preview channel may be used for installation checkout. An active subscription to the Sirius Radio service is required to listen to other channels. Instructions for activating the Sirius Radio service are located in the Pilot’s Guide, Part Number 970-0350-PG.


L IST OF THE MAJOR COMPONENTS

The following is a list of the major components that make up the equipment system complying with the standards prescribed in TSO-C157. The WSI Broadcast Datalink Receiver AV-300/350 System consists of a receiver, antenna, and a compatible Display.

DISPLAY

The receiver can serve multiple external displays. Each display interfaces to the receiver through its own bi-directional RS-232 port. One of the two RS-232 ports (COM1) is also available as an RS-422 port. The RS-422 transmit port may always be used to support a single receive-only display; however the RS-422 receive port should only be used when the COM1 RS-232 port is not used. Either of the RS-232 ports may be used asynchronously, but the COM1 RS-232 port may also be used synchronously. Contact WSI for information regarding compatible displays.

The display device(s) may require hardware and/or software upgrades to display AV-300/350 weather data products. Contact the Display manufacturer for details.

NOTE: The AV-300/350 weather data products will vary with subscription level from the weather service provider and the type of display device used. Contact the display manufacturer and/or the weather service provider for further details.

The AV-300/350 uses identical display communication protocol as the WSI AV-100/200 System. If an AV-100/200 is being replaced with an AV-300/350 system, update all appropriate aircraft records after the installation is complete. (E.g. Aircraft Weight and Balance, Aircraft Flight Manual/Supplement(s), Aircraft Equipment List, etc)

Section 2 INSTALLATION

GENERAL

The following information is designed to give the technician guidance in planning installations and efficiently troubleshooting problems with the WSI AV-300/350. If there are any problems or difficulties experienced in installing or maintaining the WSI AV-300/350, please contact WSI Customer Support (see Factory Service Policies).

RS-232 CONNECTIONS

RS-232 connections require both transmit and receive signals. Twisted shielded pairs or triplets should be used. Excessive EMI from other aircraft equipment penetrating these lines can cause data errors or dropouts on the communication port. Unused RS-232 receive inputs should be tied to ground.

RS-422 CONNECTIONS

The RS-422 port shares common hardware with the COM1 RS-232 port. Generally the RS-422 receiver port should not be connected. The RS-422 transmit port may be used to connect an additional display, even when the COM1 RS-232 port is connected; however the RS-422 receive port should never be connected.

SATELLITE ANTENNA INSTALLATION

Structural substantiation of the antenna location is important and the responsibility of the installing agency.

REMOTE CONTROL ANTENNA PLACEMENT EVALUATION

The remote control antenna should be placed so that it has an unobstructed line-of-sight view of all locations where the remote control may be used. Metal obstructions particularly will cause substantial degradation of the RF signal between the remote control and the AV-350 receiver. It is recommended that candidate locations for the remote control antenna be tested before permanently mounting the antenna. The following steps may be used to confirm the candidate remote control antenna location:

NOTE: Sirius Radio Receiver must be activated prior to performing this procedure.

1. Temporarily mount the antenna in the candidate location. 2. Turn on the AV-350 receiver and tune to a station so that audio can be heard. 3. Sit in one of the locations where the remote control may be used. 4. Change the station by pressing the channel up or down button. 5. Confirm that the new station is identified on the remote control display. 6. Confirm that the radio station was change by listening to the audio. 7. Repeat steps 3 through 6 for each location where the remote control might be used.


RECEIVER ANTENNA CONNECTIONS

Do not over-tighten the connector or internal damage to the receiver or the antenna could result. The connector on the receiver and antenna is hard mounted. If a connector turns in its mounting, it needs to be repaired.

POWER INPUT L INE AND GROUND RETURN

Ensure that the receiver is well grounded to an effective airframe ground. Poor grounds or ground loops can cause intermittent operation or alternator noise in the headphones. If there is any question about the effectiveness of the ground, route the return line to the battery terminal.

AUDIO

The AV-350 audio output is designed to operate into a 600-ohm load. If an audio port must be shared with another audio input, series resistors should be used in both lines to allow sufficiently high audio volume for both audio inputs. Usually 220 to 470 ohm resistors are satisfactory.

Connection to an audio panel without internal amplification may require a supplemental amplifier. Low audio is usually caused by a greater than normal load on the line due to multiple inputs to one audio port.

A dedicated audio ground return line is provided to eliminate possible audio whine. Connect the audio return to the ground for the audio port to which the AV-350 receiver is connected. If no return ground is provided, ground to the case of the audio panel.

The audio line from the AV-350 receiver to the audio panel should be shielded, with the shield grounded at the audio panel.

NOTE: All AV-350 audio installations that have audio available to the flight crew must have an audio mute switch installed, and have the AV-350 audio suppression connected to all higher priority equipment. The audio mute switch should be installed in a position easily accessible to the pilot. This will allow the flight crew to quickly MUTE the AV-350 audio when needed. The AV-350 audio suppression line must be connected to higher priority systems to prevent the AV-350 audio from interfering with communication, navigation, and safety systems. All other systems audio alerts are higher priority than AV-350 audio.

INSTALLATION IN A SEVERE EMI ENVIRONMENT

Proper grounding of the AV-300/350 receiver is essential. If the EMI environment is anticipated to be severe, route the cable bundles through an overall shield (in addition to the shields specified in the wiring diagrams). The outer shield should be terminated to aircraft ground at the receiver end of the cable bundle.


GENERAL INSTALLATION CONSIDERATIONS

The WSI AV-300/350 should be installed according to this manual, AC 43.13-1 ( ) and AC 43.13-2 ( ). Cable harnesses and mechanical supports must be fabricated by the installing agency to these requirements. This Section contains interconnect diagrams, mounting dimensions and other information and tips pertaining to installation. Refer to Section 3 page 47 for checkout instructions.

GETTING STARTED

Prior to beginning the system installation, the installer is strongly encouraged to read these installation procedures completely. Planning the entire process ahead of time will help avoid problems once the installation has begun.

Exercise care when unpacking the equipment. Make a visual inspection of the unit for evidence of damage incurred during shipment. If a claim for damage is to be made, save the shipping container to substantiate the claim. The claim should be filed with the transportation company. Retain the container and packaging material after the equipment has been removed should equipment storage or reshipment become necessary.

CLAMPING AND ROUTING WIRES

Wire bundles should be secured approximately every 12 inches (30cm) with nylon strapping or other appropriate materials. The wire bundles should be secured to the airframe at regular intervals to prevent any interference with control cables and to prevent wire chafing. Route the wires away from critical circuits. Route the audio wires separately from the power lines to minimize audio interference.

RECEIVER GROUNDING

The AV-300/350 receiver case is electrically conductive. The preferred method of grounding the receiver is through the mounting screws. If it is not practical to provide an electrical connection between the airframe ground and the case of the receiver, then a ground strap must be installed from pin 1 of the communications and power connector (P1) to a nearby airframe ground. If required, attach a 22 AWG ground strap (item 1) from pin 1 of P1 to a nearby airframe ground. The ground strap should be no longer than 18 inches (45.7cm).

CABLE SHIELDS

Dress all cable shields back so they are electrically bonded to the communication and power connector (P1) back shell. Unless otherwise specified, cable shields should be grounded to airframe ground only at the AV-300/350 receiver end of the cable.

SATELLITE ANTENNA PLACEMENT

Use the following guidelines to ensure a suitable placement for the AV-300/350 satellite antenna:

a) The satellite antenna must be mounted on an external top surface of the aircraft.


b) The satellite antenna should be mounted so that it is within 15° of level when the aircraft is in straight and level flight.

c) The satellite antenna should be located 36 inches or more away from the nearest transmitting antenna.

d) The AV-300/350 satellite antenna requires a ground plane to achieve optimal performance. Metal aircraft should have a good bond between the airframe and the AV-300/350 antenna to provide an adequate antenna ground plane. Satellite antenna installations on composite aircraft require the installation of metallic foil strips, to the inside of the aircraft, to provide the antenna ground plane.

e) The satellite antenna should have a clear (no aircraft obstructions) line-of-sight view of the sky above 60 degrees of elevation.

f) See Satellite Antenna Installation on page 43 for additional information.

REMOTE CONTROL ANTENNA PLACEMENT

Use the following guidelines to ensure a suitable placement for the AV-350 remote control antenna:

a) The remote control antenna cable should be at least 18 inches long.

b) The remote control antenna must be mounted inside the aircraft.

c) The remote control antenna should be located to maximize reception from the remote control. First determine all locations within the aircraft where an occupant may utilize the remote control, and then position the antenna so that it has reliable reception from those locations. The antenna may be able to receive signals through non-metallic objects and surfaces; however metallic or electrically conductive obstructions should be avoided.

d) The remote control antenna may be mounted to metallic structures; however poor reception may result at locations where the mounting surface obstructs the view of the antenna.

e) Avoid locating the remote control antenna inside the cabin within 12” of any external antenna, especially in composite aircraft or other aircraft with non-metallic skin. If it is necessary to mount the remote control antenna within 12” of an external antenna be sure to carefully evaluate the AV-350 and the system associated with the other antenna for possible RF interference.

f) The AV-350 receiver may be mounted prior to mounting the remote control antenna so that candidate locations may be evaluated. It is a good idea to evaluate the proposed location both before and after permanently affixing the antenna.

g) The remote control antenna may be mounted in any orientation for optimal performance.

h) See Remote Control Antenna Installation on page 46 for additional information.


RECEIVER INSTALLATION

RECEIVER MOUNTING The AV-300/350 receiver is normally installed in the avionics bay. The receiver mounting location must be structurally adequate. The supporting structure and attachments must be able to withstand the appropriate loads for the type of aircraft and the location within the fuselage. Refer to regulatory and industry guidance for current information.

The AV-300/350 receiver may be mounted either vertically or horizontally. Allow adequate space for installation of cables and connectors. See Figure 2 on page 33 for the AV-300/350 receiver dimensions

Mount the receiver in an accessible location using four 8-32 stainless steel Phillips pan head screws tightened to 30 inch pounds using self-locking retainers.

EQUIPMENT INTERFACES

This section describes how to connect the AV-300/350 receiver to the various equipment to which it interfaces. Connector pin assignments are shown in Table 2-A on page 36.

Discrete Interfaces

The AV-300/350 receiver supports the following discrete interfaces. Unless otherwise noted, unused discrete inputs should be left unconnected.

Standby Input: Optional. This input may be connected to a panel mounted switch to allow the system to be shut down. When this input is connected to ground the AV-300/350 receiver enters the standby condition. This is effectively the same as removing power from the receiver.

Mute Input: Optional. Asserting the mute input will mute the audio on the AV-350 receiver. This signal may also be sent over a serial interface from a display that supports the audio mute capability. A Single Pole Single Throw (SPST) switch can be installed to provide a convenient backup for the remote control. The Mute function is not required but it is recommended. There are two mute inputs, Mute+ is asserted with a positive voltage, Mute- is asserted with a ground.

Audio Suppression Input: The audio suppression input must be used when higher priority warning systems are installed and the audio from the AV-350 receiver is connected in a manner that would interfere with the flight crew’s ability to clearly discern the higher priority warnings (all other warning systems are higher priority). Connect the Audio Suppression input to the audio suppression output of all higher priority warning systems such as TAWS, EGPWS, TAS, or TCAS. This input accepts a ground potential to suppress audio.

Channel Up Input: Optional. The Channel Up discrete input may be used to provide a backup method of selecting the next higher audio channel when the connected display(s) do not provide channel selection capability. This provides a backup for the handheld RF remote control. A momentary switch or pushbutton to ground can be installed for the Channel Up input.

Channel Down Input: Optional. The Channel Down discrete input may be used to provide a backup method of selecting the next lower audio channel when the connected display(s) do not provide channel selection capability. This provides a backup for the handheld RF remote control. A momentary switch or pushbutton to ground can be installed for the Channel Down input.


Volume Up: Optional. The Volume Up discrete input may be used to provide a backup method of increasing the audio volume when the connected display(s) do not provide volume control capability. This provides a backup for the handheld RF remote control. This input would connect to a momentary switch to ground.

Volume Down: Optional. The Volume Down discrete input may be used to provide a backup method of decreasing the audio volume when the connected display(s) do not provide volume control capability. This provides a backup for the handheld RF remote control. This input would connect to a momentary switch to ground.

Audio Panel Interface

The AV-350 receiver provides a stereo audio output of the Sirius radio broadcast for entertainment purposes. Control of the audio channel is typically done with a wireless remote control. If the stereo audio output is connected to the audio panel in a manner that permits the pilot to hear the entertainment content, then the audio suppression input must be used to mute the entertainment audio during higher priority audio warnings.

The second stereo audio output is for future expansion. This second audio output will not be suppressed by the audio suppression input; therefore if this output is connected to the audio panel it must not be connected so that it can be heard over the cockpit speaker or the pilot/copilot headsets. The second audio output is for passenger entertainment only.

Display Interface

Each of the AV-300/350 RS-232 communication ports can support an independent display device. One additional listen-only display is supported by the RS-422 transmit port. The RS-232 ports are designated COM1 and COM2. COM1 output only is also available on the connector as an RS-422 interface. Both the RS-422 and RS-232 outputs of COM1 may be used at the same time; however DO NOT connect to the RS-422 receive ports of COM1. One display can be used per port. The wiring connections can be made to any available RS-232 or RS-422 port. Figure 5 shows the AV-300/350 connected to various displays. Connect the AV-300/350 receiver to the display and configure it in accordance with the display’s installation documentation. Contact WSI for a list of compatible displays.

Electronic Flight Bag Interface

The AV-300/350 provides an RJ-45 Ethernet interface for connection to electronic flight bags (EFB). Refer to FAA Advisory Circular 120-76A and installation instructions provided with the EFB device for installation and system checkout procedures. Connecting to this port requires installation approval beyond the scope of STC SA00258BO and this manual.

RECEIVER CONNECTIONS

This section describes the wiring connections between the AV-300/350 receiver and the various components to which it interfaces.


Communication and Power Connector (P1)

Wire the communication and power connector (P1) according to the pin assignments are illustrated in Figure 3 on page 39 and in Figure 4 on page 40. All wiring should be secured to prevent chafing and faulty connections. Unless otherwise noted, use the following guidelines when making connections to the AV-300/350 receiver.

• Use 22 AWG stranded wire.

• Strip the wires back 0.14 inches (3.56 mm).

• Terminate shielded cables to chassis ground only at the AV-300/350 receiver end of the cable.

Figure 3: AV-300/350 Receiver Wiring Diagram – Communications Connections


Figure 4: AV-300/350 receiver Wiring Diagram – Audio, Power and Discrete Connections

(Audio connections only available on the AV-350)


Note 1. Standby – Optional, switch to Ground places unit into standby mode. NOTE: This input shuts down the receiver’s power (including weather data reception). Returning to the operational state is equivalent to a power-on condition. Some data products are transmitted at very long intervals and may not be available for viewing for many minutes following a return to the operational state.

Note 2. RS-232 Ports – A twisted shielded triplet can be used, or use two twisted shielded pairs so that each signal is twisted with a signal ground wire. Ground any unused RS-232 receive (RX) inputs.

Note 3. RS-422 Port – The COM1 RS-232 and COM1 RS-422 ports use the same communications hardware and are not independent. Receive connections are not used for the RS-422 interface – it is an output-only port. The COM1 RS-422 transmit port will transmit the same data that is transmitted on the COM1 RS-232 transmit port. It is okay to use both the RS-232 transmit port and the RS-422 transmit port of COM1 so that an additional display may be driven.

Note 4. RTS and CTS – These are optional synchronous communications signals that can be used in conjunction with the COM1 RS-232 port. Connect COM1 RTS (pin 4) to COM1 CTS (pin 45) for asynchronous operation with the COM1 RS-232 port or for operation with the COM1 RS-422 port. Note that most displays do not require the use of the RTS and CTS signals. If RTS and CTS connections are required for a display, a receiver configuration chance must be made to enable the use of these pins for COM1. Contact WSI Customer Support for information on how to do this.

Note 5. Audio Signals – A twisted shielded triplet can be used, or use two twisted shielded pairs so that both left and right channels are twisted with the associated audio ground wire. Connect the audio ground to the audio panel and the AV-300/350 receiver to eliminate common mode noise.

Note 6. Reserved for future use, do not connect.

Note 7. Chassis Ground – The chassis ground input pin must be connected to the airframe ground if the case is not electrically connected to the airframe ground. If the case is electrically connected to the airframe ground, then this pin may be left unconnected.

Note 8. These pins are reserved for future use and should not be connected.

Note 9. Power – A trip-free re-settable circuit breaker must be installed between the aircraft electrical bus and the AV-300/350 receiver. Aircraft battery and its return should be twisted pair. Shielding is optional. Do not connect this device to the essential electrical bus.


Note 10. No Connection – Pins identified as “No Connection” must not have an external connection. It does not mean that there is no internal connection to that pin. Any external connection to a “No Connection” pin could cause permanent damage to the AV-300/350 receiver and will void the warranty.

Note 11. Mute – The AV-350 receiver always powers up with the audio mute disengaged. Asserting either of the optional Mute inputs will toggle the state of the audio mute. The Mute- (pin 14) input is asserted with a connection to ground. The Mute+ (pin 55) input is asserted with a connection to a positive voltage (between +5V and aircraft battery level).

Note 12. Reserved for future use, do not connect.

Note 13. Signal Grounds – The signal grounds are interchangeable. Although the wiring diagram indicates a specific signal ground pin number, any signal ground may be used.

Note 14. Audio Suppression – This input is grounded to suppress audio from the AV-350 receiver and must be connected to the audio suppression output of any higher-priority devices such as TAS, TCAS, and TAWS.

Note 15. Diagnostic Port (Optional) – The diagnostic port is used only during ground diagnostic activities. For in-flight operation the Rx pin (pin 51) should be connected to signal ground.

Satellite Antenna Connector (J1)

The satellite antenna connector is labeled J1 on the AV-300/350 receiver. It is a 50Ω TNC connector. Use 50Ω coax with TNC connectors on each end to connect between J1 on the receiver and the satellite antenna.

Remote Control Antenna Connector (J2)

The remote control antenna connector is labeled J2 on the AV-350 receiver. It is a 50Ω BNC connector. Use 50Ω coax with BNC connectors on each end to connect between J2 on the receiver and the remote antenna. The remote control antenna connector adapter is used to adapt from the BNC connector on the cable to the Reverse Polarity SMA (RP-SMA) connector on the remote control antenna.

It is acceptable to install the remote control antenna without using the connector adapter; however it is the responsibility of the installing agent to select a RP-SMA connector that is appropriate for the type of 50Ω coax being used. In this case the selected RP-SMA connector would be installed at the remote control antenna end of the 50Ω coax instead of a BNC connector.


Ethernet Connector (J3)

This connection is unused in applications covered by STC SA00258BO. The Ethernet port is capable of transmitting weather data to other electronic devices. Connecting to this port requires installation approval beyond the scope of the STC and this manual. (Reference Electronic Flight Bag on page 35) Electronic Flight Bag Interface

USB Connector (J4)

The USB connector is only used for field software updates and service. No connections should be made to J4 unless instructed to do so by support personnel or software update instructions.

SATELLITE ANTENNA INSTALLATION

EVALUATING SATELLITE ANTENNA LOCATION ON THE AIRCRAFT

Prior to mounting the antenna to the aircraft, a suitable location for its placement should be identified. Follow the guidelines outlined in Satellite Antenna Placement on page 30 when considering a location for the antenna. If no suitable location can be found for the antenna, contact WSI Customer Support for further assistance.

SATELLITE ANTENNA MOUNTING

Refer to industry guidance for instructions on proper antenna and backing plate installation and sealing. Use the guidance in AC43.13-2b, Chapter 3. Additional installation approval is required for installing the AV-300/350 antenna on pressurized and composite aircraft.

The antenna is mounted as follows:

(a) Identify the proper location for the antenna. Use the guidance in AC43.13-2b Chapter 3 to verify proper mechanical mounting.

(b) Prior to installing the antenna on metal aircraft, clean the aircraft skin where the antenna will be mounted. Remove the paint externally and properly treat the area where the paint was removed with conductive Alodine or a similar corrosion protection material to assure a good electrical bond to the ground plane.

(c) Drill holes for the connector and mounting screws in accordance with the Installation Instructions included with the antenna.

(d) Mount the antenna on the outside of the aircraft using the screws identified.

(e) The antenna must be mounted on the top of the aircraft.

(f) An additional internal metallic ground plane of 12-inches or more is required for composite aircraft.

NOTE: Structural substantiation of the antenna locations is important and is the responsibility of the installing agency. If a structural DER is necessary, the Aircraft Electronics Association is a good source of information. The telephone number is +1 (816) 373-6565.


A good ground plane and good bonding between the antenna and the ground plane is important to achieving optimal performance of the AV-300/350 receiver.

SATELLITE ANTENNA CONNECTIONS AND WIRE ROUTING

Route the wire according to industry guidelines. Avoid routing AV-300/350 cables with critical aircraft wiring or with other transmitter antenna cables.


REMOTE CONTROL ANTENNA INSTALLATION

EVALUATING REMOTE CONTROL ANTENNA LOCATIONS

Prior to mounting the antenna within the aircraft, a suitable location for its placement should be identified. Follow the guidelines identified in Remote Control Antenna Placement on page 28 when considering a location for the antenna. If no suitable location can be found for the antenna, contact the WSI Customer Support for further assistance.

REMOTE CONTROL ANTENNA MOUNTING

The antenna is mounted as follows:

(a) Identify the proper location for the antenna.

(b) Affix the antenna using appropriate non-conductive straps.

(c) Affix the antenna cable near the antenna connector using an appropriate strapping mechanism to minimize strain on the antenna connector.

(d) Verify proper remote control reception at all locations where the remote control is likely to be used.

REMOTE CONTROL ANTENNA CONNECTIONS AND WIRE ROUTING

Route the wire according to industry guidelines. Avoid routing AV-350 cables with critical aircraft wiring or with other transmitter antenna cables. The remote control antenna cable should be at least 18 inches and no more than 50 feet. Longer cables may be used, but will result in reduced range to the remote control.

Section 3 INSTALLATION CHECKOUT

GENERAL

These Installation Checkout procedures should be performed after initial installation of the AV-300/350 system or after any part of the system has been serviced. Successful completion of these procedures will help assure that the system achieves its specified performance levels in day to day operation.

POWER UP

CAUTION : Before applying power to the system, verify that all cables are properly connected and terminated.

The AV-300/350 receiver normally powers up with the Avionics Master switch. If the receiver has been connected to the optional external standby switch, it can be used to place the receiver into standby mode, which is essentially the same as turning the receiver OFF.

NOTE: The AV-300/350 receiver requires approximately three minutes to initialize after power is applied or after the optional standby switch is deactivated. Audio and data products will not be available prior to completion of the power-on initialization sequence. The 420-0350-RM Remote Control will connect to the AV-350 following the power-on initialization. Prior to the 420-0350-RM Remote Control connecting to the AV-350 Receiver, the AV-350 audio can only be muted using discrete mute inputs on the AV-350 Receiver.

INSTALLATION CHECKOUT PROCEDURES

DISPLAY INTERFACE

Using the display manufacturer’s installation instructions, verify the AV-300/350 Receiver is communicating properly with the display.

STANDBY SWITCH

If a standby switch is installed, verify the standby switch is in the normal operating position. Verify the AV-300/350 is receiving weather data. Toggle the Standby switch to the standby position. This is accomplished by grounding P1-pin 54. Verify the display device annunciates a AV-300/350 failure (Some display devices may take longer to annunciate).

AUDIO INTERFACE

Verify the audio volume can be adjusted to an acceptable volume.

If the AV-350 audio is connected to an Audio Control Panel, verify the AV-350 audio is functioning per the Audio Control Panel’s installation manual. If the AV-350 audio is available


to the flight crew, verify the AV-350 audio does not interfere with the flight crew’s ability to hear other aircraft systems.

AUDIO SUPPRESSION INPUT

If the audio suppression input is used, it may be tested by listening for the AV-350 audio to mute while causing each suppressing device to assert its audio suppression output.

AUDIO MUTE INPUT TEST

The audio mute switch can be tested by switching the audio mute switch to the MUTE position while listening to the AV-350 audio. This is accomplished two ways, by either grounding P1-pin 14, or connecting positive voltage to P1-pin 55.

AUDIO CHANNEL TEST

If an audio channel switch is installed, it may be tested by either momentarily grounding P1-pin 17 for channel up or P1-pin 18 for channel down. (AV-350 only)

AUDIO VOLUME TEST

If an audio volume switch is installed, it may be tested by either momentarily grounding P1-pin 15 for volume up or grounding P1-pin 16 for volume down (AV-350 only)

Section 5 REMOTE CONTROL

REMOTE CONTROL OPERATION

Refer to AV-350 Pilot’s Operating Handbook, part number 970-0350-PG, for operating instructions.

REMOTE CONTROL PAIRING PROCEDURE (FOR AUDIO-ENABLED UNITS ONLY )

This procedure is not needed for new AV-350 Receivers. New AV-350 units are paired at the factory to the 420-0350-RM remote control. However, there are some circumstances that may require the remote control and receiver to be paired again. Some examples of conditions that may necessitate repeated pairing are:

• The batteries were removed from the remote control for too long.

• If you replaced your remote due to loss or damage.

NOTE: Activation to Sirius Radio is a prerequisite to pairing the 420-0350-RM Remote Control and AV-350 Receiver.

PAIRING - If the 420-0350-RM Remote Control is new or not paired, pair it using the following steps:

1. The aircraft must be outside and have a clear unobstructed view of the sky.

2. Press any button to activate the 420-0350-RM.

3. The 420-0350-RM will display: “SIRIUS radio has not been setup. Push “OK” to setup.” DO NOT PUSH “OK” AT THIS POINT!

4. To pair the devices, apply power to the AV-350 receiver and note the exact time.

5. At the 45 second mark, press any button to activate the 420-0350-RM, and then press “OK.” The 420-0350-RM should briefly display the “SUCCESS” message. Proceed to Step 8 after “SUCCESS is observed, if “SUCCESS” is not observed proceed to Step 6.

6. At the 2 minute 30 second mark, press any button to activate the 420-0350-RM, and then press “OK.” The 420-0350-RM should briefly display the “SUCCESS” message. Proceed to Step 8 after “SUCCESS” is observed, if “SUCCESS” is not observed proceed to Step 7.

7. If the SUCCESS message is not observed before the 420-0350-RM times out, power-down the avionics, wait thirty (30) seconds, and repeat the pairing procedure.

8. If the SUCCESS message is observed, Press the Sirius radio button. The remote will display the current Sirius channel information when it is received.


REMOTE CONTROL UN-PAIRING PROCEDURE (FOR AUDIO-ENABLED UNITS

ONLY )

NOTE: Only use this procedure when an AV-350 Receiver is replaced with a different unit.

UN-PAIRING - If the AV-350 is replaced with a new AV-350, un-pair the existing 420-0350-RM Remote Control from the previous AV-350 using the following steps:

1. Press any button to activate the 420-0350-RM Remote control.

2. Press and hold the "Set" button in upper left corner until remote displays "SIRIUS SETUP or INITIAL SETUP."

3. If it displays "INITIAL SETUP," use the arrow buttons to scroll through to "SIRIUS SETUP."

4. Press the "ok" button located right under the screen, the remote will display "NODES."

5. Press the right arrow and the 420-0350-RM will display "NETWORK,"

6. Press "ok," and the remote will display "NETWORK RESET."

7. Press "ok," the remote will display "SUCCESSFUL."

After a successful un-pairing, the 420-0350-RM can be paired to a different AV-350 receiver using the Remote Control Paring Procedure.

REPLACING BATTERIES IN THE 420-0350-RM REMOTE CONTROL

To change the batteries in the 420-0350-RM Remote Control, slide the battery cover off the back of the remote, replace the 4 AAA batteries, and replace the back cover. Removing batteries briefly and replacing them promptly will not typically result in a need to re-pair the 420-0350-RM Remote Control with the AV-350, however, it is possible for the devices to become unpaired. In the event that pairing is lost, repeat the pairing procedure as defined in the previous section.


Section 6 TROUBLESHOOTING GUIDE The following table lists some of the possible failure modes of the AV-300/350 receiver, and recommends some possible causes and solutions. If the issue cannot be resolved with these recommendations, contact WSI Support.

Table 5-6-A: Failure and Warning Conditions and Possible Solutions

Problem Possible Causes and Solutions

Broadcast receiver antenna is disconnected

AV-300/350 satellite antenna is damaged, coax cable or connectors are not installed properly, or antenna disconnected

• Check connection to the AV-300/350 receiver.

• Check connection between AV-300/350 receiver and antenna.

• Check connection to the antenna.

• Check RF connectors on antenna cable.

• Check for >3VDC on AV-300/350 satellite antenna connector.

Broadcast receiver not communicating

Display improperly configured, RS-232 wiring issue, AV-300/350 not powered

• Refer to MFD installation manual for proper Broadcast configuration and wiring interconnect diagrams.

• Refer to AV-300/350 Receiver Installation Manual for power wiring.

Broadcast data not received No data products have been received, but unit is otherwise operating properly.

• Check User’s account with Sirius.

• Check radio authorization with WSI Customer Support



Broadcast radio is not received (remote control IS displaying channel and song data)

No audio is heard, but the remote control is displaying channel and song data.

• Confirm that the audio mute is not engaged.

• Confirm that the audio wiring from the AV-300/350 to the audio panel is correct.

• Confirm that the audio wiring and connectors are sound.

• If the audio suppression input is used, confirm that all audio suppression outputs connected to it are asserted (muted) low.

• Confirm that the audio suppression input is not shorted to ground.

• Confirm that the asserted low mute discrete input is not shorted to ground and that the asserted high mute discrete input is not shorted to a positive voltage.

Broadcast radio is not received (remote control is NOT displaying channel and song data)

No audio is heard and the remote control is not displaying channel or song data; however the remote control does appear to be communicating with the receiver.

• Check user’s account with Sirius radio.

• Check receiver audio product authorization with WSI Customer Support

Not receiving all weather data products.

• Call WSI Customer Support to check the user’s weather service account activation status.



Remote control unable to communicate with the receiver

Remote control is not paired with the receiver, the remote control antenna is not properly connected, or the remote control antenna is not located in a suitable location.

• Check the connection between the remote control antenna and the receiver.

• Check for obstructions (especially metallic obstructions) between the remote control antenna and then remote control. Obstructions will reduce reliability of the connection between the remote control and the receiver.

• If there are no obstructions between the remote control and the remote control antenna, then move the remote control closer to the remote control antenna. If the remote control works when closer to the antenna, then either unexpected obstructions exist or the connection between the receiver and the remote control antenna is poor causing degraded communications.

• If the remote still does not communicate with the receiver, follow the instructions for un-paring and re-pairing in the WSI Broadcast Datalink Receiver Pilot Guide, P/N 970-0350-PG.
