SECTION 2: INSTALLATIONPROPER GROUNDING PRECAUTIONS ARE REQUIRED AT ALL TIMES TO PREVENT DAMAGE FROM ESD WHILE HANDLING THIS UNIT

UNPACKING, STORAGE, RESHIPMENT

Carefully open the shipping container and remove the equipment. Inspect the equipment thoroughly and report any damage.

If the equipment is to be stored, it should be wrapped in plastic and kept in a clean, dry place.

If the equipment is to be reshipped for any reason, wrap in heavy plastic and ship in a heavy (275 lb. test) double wall carton. At least three inches of a solid packing material should be used on all sides of the unit. The carton should be marked to indicate that it contains fragile electronic equipment.

MOUNTING

This equipment is NOT for use in a domestic environment. It is intended for rack mounting. This equipment MUST be securely mounted; Operator injury may occur if this is not done.

!CAUTION

Frame OL-TR3-20 is provided for mounting in a standard 19” equipment rack.

TURN-ON PROCEDURE

• After mounting, make all external connections per Table 2-1. • Apply power to the equipment by connecting the AC input to a suitable power source. • Allow 20 minutes for warm-up of the internal crystal oscillator reference. The unit should be left in the power-on

state for 24 hours in order to reach the specifi ed performance for frequency stability. • System is now operational.

Note This system includes a feature that allows the user to disable nonvolatile memory writes (to save current settings and update event logs) when the unit settings are changed by way of remote commands. • The feature disables nonvolatile memory writes in response to remote commands that change band,

frequency, attenuation, attenuation 2, IF frequency, slope, impedance and mute. • The Remote Nonvolatile Memory Writes are disabled from the unit’s front panel as follows:

1. Power On the unit while holding the UP arrow key2. When the display reads the following, release the UP arrow key:

SECTION 3: OPERATION CONTROLS

EXTERNAL CONTROLS

AC PowerApply AC power to the unit connecting the line cord supplied to the unit and then to an approved AC power source. Upon Power-up a one-second beep sounds and the LCD backlight will be lit when power is on.

FuseThe fuse is accessible from the rear panel of the unit, in the corner where the AC input is located. The fuse value is T1.25A.

FRONT PANEL OPERATIONS

A Liquid Crystal Display (LCD) and Light Emitting Diode (LED) indicators have been organized such that important information is available at a glance. The keypad has been arranged to allow an operator to easily change any parameter from the front panel. See Figure 1-1 for the physical layout of the front panel.

INDICATOR BUTTONS

The “STATUS” indicator button LED will light red to indicate an active fault in the Frequency Converter. The indicator button LED will light amber when there are no active faults but fault events have been stored in the log and the log has not been cleared. Pressing the “STATUS” button will provide instant access to the Status screen information. Pressing the “STATUS” button repeatedly will toggle the context of the display between the Fault Status screen and the Main screen.

The green “REMOTE” indicator button LED is lit when the unit is in remote control mode. When the “REMOTE” indicator button is not lit, the unit is in local control mode. Operating parameters can be monitored from the front panel and from the remote port at all times. When the unit is in remote control mode operating parameters can only be changed from the remote ports. When the unit is under local control, operation parameters can be changed from the front panel only. The unit will always power up in remote control mode. Also, after thirty minutes of inactivity at the front panel, the unit will revert to remote control mode. The unit will always power up in remote control mode.

The “RF ON” indicator button LED will light green when the unit is carrying communications traffi c. The “RF ON” indicator button LED is not lit when the output is mute, interrupting communications traffi c. While in local mode the operator can press the “RF ON” indicator button to toggle the output between Mute and “RF ON” (provided that there are no active faults). When a fault is active the output is forced to mute and the “RF ON” LED cannot be switched. After the fault extinguishes and is no longer active the user-programmed state will be restored.

SCREEN NAVIGATION AND DATA ENTRY

The keypad includes four directional arrow keys for navigation and data entry. An “ENT” key is used for confi rming data entries. A beeper will sound to acknowledge each key press. An error tone will sound for illegal entries. While in Remote mode, local data entry is prohibited. However, all system parameters can be examined.

The cursor will appear as either two vertical arrows, an up arrow “↑” on the top line and down arrow, “↓” on the bottom line, or as a single right arrow “→”. This indicates the direction of navigation. While the cursor appears as two vertical arrows use the up and down arrow keys to navigate between screens. Press the left or right arrow key and the cursor will appear as a right arrow “→”. When the cursor is a right arrow “→” the data fi eld to the right of the cursor is selected and the up and down arrow keys are used to change the data in the selected fi eld. Use the left and right arrow keys to navigate between fi elds within a screen.

Pressing the “STATUS” indicator button will exit the data entry mode and resume the screen navigation mode with the cursor returning to the two vertical (”↑” and “↓”) arrows at the left of the screen. Repeated presses of the “STATUS” indicator button will toggle the display between the Fault Status screen and the Main screen.

SERIAL PORT DESCRIPTION

The unit is supplied with an RS485/422 remote interface port. Status is always available at the RS485/RS422 remote port regardless of control mode. Selection of Remote or Local control mode is available at the front panel only. The unit defaults to Remote control upon power-up. If the unit is left in Local control mode, after thirty minutes of inactivity the unit will switch to Remote control mode.

The RS485/RS422 serial port can be set to RS485 for two-wire operation or RS422 for four-wire operation from the front panel local interface. This port supports a multi-drop bus arrangement. The RS485/RS422 interface parameters such as address, baud rate and parity can be set from the front panel. All transmissions on the RS485/RS422 port are multi-byte sequences beginning with a header byte and ending with a trailer byte followed by a checksum byte. The transmitted bytes are all ASCII printable characters in the range of 20H to 7EH. The RS485/RS422 monitor and control protocols are described in detail later in this section of the manual.

All messages addressed to the RS485/RS422 port are acknowledged with a response message. The unit continually monitors the RS485/RS422 port and will accept commands, addressed to it, even in Local mode. When in Local mode, receipt of any SET commands (commands beginning with “$”) at the RS485/RS422 remote port will be ignored and the unit will respond with an error code.

REMOTE MESSAGE PROTOCOL (RS485/RS422)

The data format is a 10-bit sequence for each character. If odd or even parity is selected the ten bits are 1 Start, 7 Data, 1 Parity, and 1 Stop bit. If the parity is set to none, the bits are 1 Start, 8 Data and 1 Stop bit.

If any character in a command message contains an error in parity, framing, overrun or the checksum is incorrect, the command is ignored and no response is made. When odd or even parity is selected, all characters, including the checksum character, are checked for parity. The response time from command to acknowledge is 100 ms. maximum.

RS485/RS422 SERIAL PORT MESSAGE FORMAT

The Serial Message Format is as follows:

HEADER - ADDRESS - COMMAND/ERROR CODE - PARAMETERS - TRAILER – CHECKSUM

The Header byte is 123 decimal (7BH, ASCII character “{“).

The address may take on the values from 64 to 95 decimal (40H to 5FH, ASCII characters “@” to “_”).

Commands are three ASCII characters preceded by an ASCII “?” or “$.” Commands preceded by “?” are QUERY commands and those preceded by “$” are SET commands. Query commands are used to examine system parameters while SET commands are intended to modify system parameters. An Error Code may be returned as a reply to an unacceptable command.

Parameters are all ASCII printable characters in the range of 20H to 7EH. Numeric parameters are sent MSD fi rst, LSD last. Values which do not adhere to the command format, or are beyond the allowable range, will be rejected and cause the unit to respond with an error code.

The Trailer byte is 125 decimal (7DH, ASCII character “}”).

The checksum byte is the sum modulo 95 of all message characters beginning with the header byte up to and including the trailer byte. The value 32 is subtracted from each character value before taking the modulo 95 sum. The value 32 is added to the fi nal sum to obtain the checksum value. All values are in decimal.

Checksum = MOD [(character value - 32), 95] + 32

Operation | 20


®

Below is a program, written in the ‘C’ programming language that illustrates the checksum calculation.

/* return the checksum character for the message in array subtract 32 from each character before taking modulo 95 sum add 32 to the fi nal sum mes_len = message length*/char check_sum(char *array, char mes_len){char i,sum; for ( i = 0, sum = 0; i < mes_len; i++ ) { sum += *array++ - 32; sum %= 95; } return(sum + 32);}

COMMAND CODE DESCRIPTION

The following paragraphs describe each of the command codes. For clarity, the header, address, trailer and checksum characters are not shown. Upper case letters are the actual command or response characters. Lower case characters represent parameter character strings.

Commands preceded by “?” are QUERY commands and those commands preceded by “$” are SET commands. QUERY commands are used to examine system parameters while SET commands are intended to modify system parameters.

For units not equipped with a variable attenuator, all attenuation queries will be returned a value of zero and all attenuation parameters in SET commands must contain a value of zero.

ETHERNET INTERFACE INSTALLATION AND OPERATION

FUNCTIONAL DESCRIPTION

The MITEQ 1/3 Rack-mounted Converter is equipped with an Ethernet Interface feature permitting control and monitoring via a 10 or 100 Mbps Ethernet connection. Available interface protocols are HTTP (web access), SNMP (Simple Network Management Protocol), and Telnet. System fi rmware can be remotely upgraded using the Ethernet port.

The use of standard protocols makes it possible to provide (password-protected) access to the Converter from any location in the world where an Internet connection is available

INSTALLATION

ConnectionThe Converter must be connected to the facility Local Area Network (LAN) network via an industry-standard 10baseT RJ45 cable. The cable should be a “direct” cable, not a “crossover” cable.

If the network supports dynamically assigned IP addresses then a valid IP will be obtained when the NSU is connected to the LAN and the NSU power is cycled. If the network does not support dynamically assigned IP addresses then a valid IP address must be obtained from a network administrator and the NSU must be confi gured to that static IP address (see Confi guring IP Operating Parameters).

The unit may also be connected directly to a PC without a LAN. To connect directly to the PC a “crossover” cable must be used. The unit then must be set to a Static IP address to communicate with the computer (see Confi guring IP Operating Parameters).

Table 3-1. Ethernet Cable Wiring

SetupSetup of the Ethernet Interface should be attempted only after the Converter is fully installed and functioning, in accordance with the Converter Operation and Maintenance (O&M) Manual. Once operating, the Ethernet Interface may be confi gured.

Confi guring Internet Protocol (IP) Operating ParametersAn Internet Protocol (IP) address and associated parameters must be confi gured in the unit so the controlling device can address it. Normally, the individual or organization managing the facility’s LAN assigns this address.

The Ethernet address and associated parameters may be confi gured either via the serial interface or via a web browser. The default factory settings are recorded on the Final Test Data Sheet.

If an IP address cannot be dynamically assigned by the network or the unit is to be connected directly to a PC then the Internet Protocol (IP) address and associated parameters must be confi gured in the unit manually.

®

For direct connection to a PC any address can be chosen but the PC must also be confi gured correctly. In this confi guration, the PC must be confi gured with a Static IP address. The procedure for this varies between operating system types and versions. Consult the operating manual or help fi les available with the computer to be used to determine the proper procedure for confi guring the computer’s IP address.

Three parameters will be required on the Converter:

ParametersParameters Factory SettingFactory SettingIP Address 192.168.1.1Subnet Mask 255.255.255.0Gateway 0.0.0.0

The computer must be confi gured with the same Subnet Mask as the Converter, but a different IP address, to connect properly. For connecting with the Converter set to the address in the example above, the following settings are recommended for the PC:

ParametersParameters PC SettingPC SettingIP Address 192.168.1.2Subnet Mask 255.255.255.0Gateway 0.0.0.0

The Ethernet address may be confi gured either via the serial interface or via a MITEQ-supplied Windows™ application (See “Confi guring via IPSetup Application”).

Changing the IP settings will disrupt any open sessions (HTML, SNMP or Telnet), cause the unit to reset and the operator will be required to reconnect to the unit at the new settings.

Confi guring via Serial InterfaceThe commands listed below may be used to enter the IP parameters. Commands must be transmitted with the standard MITEQ protocol, as described in the O&M manual. Note that the factor default settings of the serial port are as follows:

ParametersParameters Factory SettingFactory SettingBaud 9600Parity OddAddress 64 (40H or ASCII: @)

CommandCommand ParametersParametersRemote Command Sequence: $EADIiiiiiiiiiiiiGggggggggggggSssssssssssssUnit Response: $EAD

EAD: Ethernet Address indicator

I: Ethernet IP Address parameter indicatoriiiiiiiiiiiii: Twelve-digit ASCII numeric characters,

G: Ethernet Gateway parameter indicatorgggggggggggg: Twelve-digit ASCII numeric characters,

S: Ethernet Subnet Mask parameter indicatorssssssssssss: Twelve-digit ASCII numeric characters,

The values may be verifi ed using the corresponding query command (?EAD).

In the response if the Ethernet Address indicator (EAD) is capitalized in the remote response, then the IP address that was set is a Static IP address. If the Ethernet Address indicator is in lower case letters (ead) then the IP address is a Dynamic IP address and was obtained using DHCP (Dynamic Host Confi guration Protocol) server to assign the IP address.Any time any one of these three parameters are changed in the Converter, it will reset itself to up date the changed parameter.

Operation | 40


®

Confi guring via IPSetup ApplicationIPSETUP.exe is a Windows™ application, which can be obtained from MITEQ. Through an Ethernet connection to the Converter, this application can re-assign the IP address of the Converter. For an example, the Converter is connected to a PC through a crossover cable. The IP address of the PC is 192.168.001.002. The address of the Converter will be set to 192.168.001.001.

1. Make sure that the Converter is in the Remote control mode.2. Open the application IPSETUP.exe.3. The application should open and show a listing of the IP addresses of what has been found by the computer. If the

Converter is unable to dynamically assign an IP address, it will show up as a unit at IP address 0.0.0.04. Highlight this address from “Select a Unit”.5. From “NDK Settings” at the “IP” line begin to enter the new IP address of the Converter.6. Press “Set→”, the Converter will reset and a few second later the new IP address should show up in the “Select a

Unit” list at IP address 192.168.1.1.7. If the list on the application doesn’t change, press “Search Again”.

Figure 3-17. IPSetup Application

Verifying Proper Connection and Confi gurationThe connection and confi guration may be verifi ed from a PC attached to the LAN using the network “ping” command. From a command prompt, enter

“ping <assigned IP address>”

The response will either indicate whether a connection was established.

Access via TelnetThe Converter may be accessed via Telnet. There is no special protocol on the Telnet channel; the Converter will expect the same commands, and offer the same replies, as via the serial port.

Telnet access must fi rst be enabled on the COMMS web page. If not being used, it is recommended that it be left disabled for security reasons.

When a Telnet connection is established, the Converter will request the password, which should be sent in the standard MITEQ wrapper (‘{‘<address byte (ignored)><password>’}’<checksum byte>). The default password is fi ve numeral ones. Since the address and the checksum are ignored on all Telnet command sequences, the password can be typed in as:

{{11111}}The connection will be refused if a user is already logged in via the web interface.

SECTION 4: PRINCIPLES OF OPERATION

INTRODUCTION

The following paragraphs provide information on the principles of operation of the 1/3 Rack Block Downconverters.

FUNCTIONAL DESCRIPTION

The block downconverter translates the RF Input frequency band to the IF output frequency band. A single conversion system is used (see Figure 4-1). Model DNB1-3.8TR-INV is a frequency inverting system. All other models are frequency non-inverting systems.

The input signal is fed to an input module. The module contains a input isolator followed by a coupler, bandpass fi lter, a low-noise amplifi er, mixer and a low-pass fi lter. The isolator provides a good match at the input and the coupler provides the RF monitor port. The bandpass fi lter provides rejection of input harmonics and provides LO rejection at the input. The low noise amplifi er set the noise fi gure for the module and provides some system gain. The mixer converts the input signal to the output IF frequency. The low pass fi lter rejects the local oscillator signal and the input RF signal as well as some mixer products. The output of the module is followed by a fi xed attenuator, which provides level adjustment and a good match to the output module.

In the output module the signal is amplifi ed and then passes through a PIN diode attenuator, which provides gain control for the system. The signal is then amplifi ed again and then is output from the system.

The reference oscillator shall be capable of receiving an external input of 5 MHz or 10 MHz. The oscillator will detect the external input frequency. If the external input signal frequency is 10 MHz, the external signal will be directed to the output. If the external signal frequency is 5 MHz, the external signal will be frequency doubled, resulting in a 10 MHz signal, which will be directed to the output.

The oscillator shall operate as an automatic reference selection switch in a SPDT confi guration. The oscillator shall switch to the internal 10 MHz oscillator if the external input signal is below a threshold level of +0.5 dBm to +1 dBm. The internal oscillator shall be turned off if the unit’s output is switched to the external input signal.

The local oscillator is a phase locked source, which is locked to the 10 MHz reference.

CRYSTAL OSCILLATOR

The oscillator is capable of receiving an external input of 5 MHz or 10 MHz. The oscillator will detect the external input frequency and phase lock to the external input. If the external input signal frequency is 10 MHz, the external signal will be directed to the output. If the external input signal frequency is 5 MHz, the external signal will be frequency doubled, resulting in a 10 MHz signal. The oscillator will then phase lock to the resulting signal. For Option 10F, the signal will be fi ltered after doubling.

The oscillator operates as an analog phase lock oscillator. The oscillator shall operate as a high-precision ovenized 10 MHz oscillator if the external input signal is below a threshold level of -1 to +0.5 dBm nominal. When the oscillator is not locked to the external signal, fi ne frequency electronic tuning will be available to adjust the oscillator output frequency. The fi ne tune voltage will not control the oscillator tune range when the external input signal is present.

For Option 10F, the oscillator shall operate as an automatic reference selection switch in a SPDT confi guration. It shall switch to the internal 10 MHz oscillator if the external input signal is below a threshold of +0.5 dBm to +1 dBm. The internal oscillator shall be turned off if the unit’s output is switched to the external input signal.

SECTION 5: MAINTENANCE

PROPER GROUNDING PRECAUTIONS ARE REQUIRED AT ALL TIMES TO PREVENT DAMAGE FROM ESD WHILE HANDLING THIS UNIT

PREVENTIVE MAINTENANCE

The equipment is a completely solid state design. Normal periodic inspection for cleanliness and mechanical integrity should be made in accordance with standard procedures.

To prevent long and costly downtime of the unit periodic monitoring of the overall performance parameters that are most indicative of individual component performance is necessary. A log should be maintained that provides a permanent record of operation and compares it to factory provided data. By doing so, any long term degradation, erratic or abnormal performance can be detected. The overall performance parameters that are most indicative of system component performance are gain and local oscillator frequencies.

Any excessive change in gain indicates a malfunction in the local oscillator and/or signal channel and/or in the power supply. Any excessive frequency change indicates malfunction in phase locking to the reference oscillator.

DC VOLTAGE

A set of power supply test points is available on the power supply. If voltage is beyond tolerance (see Page 62), reset power supply (refer to Figure 1-3), using the tuning adjustment on the power supply.

GAIN OF THE CONVERTER

The gain of the converter should be periodically monitored to reveal deviations, which would indicate possible malfunction.

FREQUENCY MEASUREMENT

Frequency accuracy of the converter is determined by the reference source used. Frequency may be monitored at the front panel LO test points.

CORRECTIVE MAINTENANCE

If the unit malfunctions during normal use or if tests reveal excessive discrepancies in gain or local oscillator frequency, isolation and correction of the malfunction becomes necessary.

While it is diffi cult to fully anticipate and describe all possible failure modes in a complicated electronic system, this manual contains suffi cient information in the form of theory of operation and diagrams to enable an experienced technician to isolate and remove the malfunctioning module.

! IT IS STRONGLY SUGGESTED THAT ANY MALFUNCTIONING COMPONENT BE RETURNED TO MITEQ FOR REPAIR.

IT IS ALSO RECOMMENDED THAT THE FAN (ASSEMBLY P/N ON PG.62) BE REPLACED ON A YEARLY BASIS FOR REGULAR MAINTENANCE.
