The DB37 bottom connector is for the DISCRETE section with 8 input and 8 output ports. Each port can be used individually as either differential RS-422 or TTL compatible operation. Also 28V compatible avionics discrete operations can be achieved for the 8 Output and 8 Input ports using the supplied DB37 adaptor.

Differential RS-422 discrete operation:

The DB37 bottom connector is for the DISCRETE section with 8 RS-422 differential inputs and outputs. A configuration DIP switch for each differential input and output can terminate the bus with 120 Ohm resistor (see Inside Chassis View chapter, sections 28 and 29).

TTL compatible discrete operation:

Each discrete input and output can also be used for single 5V TTL compatible signal as follows:

TTL compatible output operation is achieved by using only the positive (+) or the inverted (-) Tx output signal with reference to ground. When using as TTL compatible output, the corresponding channel termination DIP switch must be set to OFF (see Inside Chassis View chapter, sections 28 and 29).

TTL compatible Input operation is achieved by using only the positive (+) RX input with reference to ground and setting the corresponding channel 1.6V threshold internal DIP switch to ON (see Inside Chassis View chapter, section 31).

28V avionics discrete operation:

All discrete inpout and output can be used for single 28V avionics compatible signal by using the supplied DB37 adaptor and setting the discrete internal DIP switches as follow:

-All channel termination DIP switches must be set to OFF (see Inside Chassis View chapter, sections 28 and 29).

-All channel 1.6V threshold internal DIP switches must be set to ON (see Inside Chassis View chapter, section 31).

When using the DB37 adaptor the inputs and outputs are characterized as follow:

- Input voltage can be in the 0-36V range and the threshold is fixed at 7.7V. Input voltage hysteresis is 200mV.

-Output driver is open collector. The user must add an external pull-up resistor between the output pin and a voltage supply source corresponding to the desired Vout (ex: 28V). The maximum supply voltage is 30V.


MAX Technologies

7 - Port selectable protocols

The DB37 top connector is the MULTI section with 8 Tx/Rx parametric channels, these channels are user programmable as:

- ARINC 429 - ARINC 717 - ASYNC RS-232, RS-422, RS-485 - CSDB - HDLC / SDLC (Synchronous) RS-422, RS-485 - DISCRETE I/O (Differential) / Frequency / Pulse generator

Using a port for discrete operation

When used for DISCRETE Input and DISCRETE output, the default mode is differential operation. Single signal discrete operation is also possible using the following setting:

Single signal output:

On the Tx port use only the high output (H) with reference to ground and leave the low output (L) unconnected.

Single signal input:

On the Rx port use only the high input (H) with reference to ground and connect the low input (L) to ground. The threshold is software programmable and the default value is 200 mV.

A minimal «4-wire» ASYNC RS-422 connection consists of 2 differential transmit data lines and 2 differential receive data lines. A 120Ω termination resistor (Rt) is recommended on each farthest receiver for high bit rate and long distance connection. This type of termination adds heavy DC loading to a system.

Another type of termination, AC coupled termination, adds a small capacitor in series with the termination resistor to eliminate the DC loading effect. See Texas Instruments AN-903 Application Note to know more about differential termination techniques.

The minimal «2-wire» ASYNC RS-485 bus connection consists of 2 twisted pair differential data lines.

For high speed and long distance communication, both end of the bus should be terminated with termination resistors (Zt) matching the cable impedance (ex. use 120Ω resistors on both ends of a 120Ω cabling). Note that for short length and low bit rate this resistor can be omitted.

When transmitters are not “always” driving the bus, two Bias resistors should also be added to the bus in order to stabilize positive and negative bus lines. Positive bias resistor should be connected to power source that match the bus voltage (ex. for 0V-5V bus, external power source of 5V should be used). Note that bias resistors along with termination impedance will affect the bus threshold which should be greater than the threshold setting of the IPM-MULTI module.

8 - ASYNC RS-422 / RS-485 ports

There are 8 channels that ca be used as ASYNC TX/RX with RS-422 or RS-485 electrical interface. Each channel has an internal switch to terminate with 120 Ohm resistor (see Inside Chassis View chapter, sections 26-27).

When used as ASYNC with RS-485 electrical interface, each TX channel must be connected to the corresponding RX channel to form an ASYNC RS-485 bus.

15 - Ethernet Address LSB

These switches can configure the LSB address of the Ethernet address 0 to 255 (8-bit binary) when the unit is not in DHCP mode. The value 00000000 correspond to 0 and value 11111111 correspond to 255.

When shipped, the default address is 192.168.0.1 and the last digit can be changed with the DIP swicth so the IP address can be configured from 192.168.0.0 to 192.168.0.255.

If a fixed IP address is required within another address range, connect the FlexMulti directly to a computer Ethernet port using its default fixed adress 192.168.0.1 and use the flexchangeip software tool (http://www.maxt.com/mxf/command_line_tools.html#flex_change_ip) to change to the desired address.

Following are step by step procedure for using the flexchangeip command tool:

1- Make sure the DHCP dip swicth is OFF (see section 15). This allows the FlexMulti to be configured with fixed IP address. The default fixed address is 192.168.0.1.

2- Setup a PC with a static IP address 192.168.0.2. Refer to Appendix A to known more on how to setup a PC Ethernet port to a specific static IP address.

3- On the PC open Command Prompt and do "ping 192.168.0.1" to verify that the FlexMulti is responding.

4- Use the flexchangeip command to change the fixed IP address to your preference http://www.maxt.com/mxf/command_line_tools.html#flex_change_ip .

For example, the command flexchangeip 0 10.10.1.200 255.255.255.0 192.168.0.1 will change the address from 192.168.0.1 to 10.10.1.200.

MAX Technologies

In this example, the last digit 200 will be overriden by the dip switches, so if you have two FlexMulti on a LAN that must be configured at fixed IP address 10.10.10.200 and 10.10.10.201 you just have to setup the dip-switch on the first unit to "200" and the second unit to "201".

The FlexMulti can also be configured to acquire its IP address from a DHCP server on the LAN instead of using a fixed IP address.

The DIP-SWITCH named DHCP is for such purpose. Using DHCP, when power ON the FlexMulti will acquire its IP address dynamically frorm a DHCP server if present on the LAN instead of using its fixed IP address.

5- Power cycle the FlexMulti. Its new fixed IP address will now be effective.

16 - Configuration Switches

These switches configure the unit for various operation mode.

Ethernet/USB - PCIe/PXIe

This switch must be on Ethernet / USB position when the FlexMulti device is connected on a LAN, directly to a computer Ethernet port or a computer using USB.

This switch must be on PCIe/PXIe position when the FlexMulti device is connected directly to a computer using a PCI-Express or PXI-Express interface card.

STANDALONE AUTORUN

This switch must be on STANDALONE AUTORUN position when the FlexMulti device runs in standalone mode from a power-on. When running standalone, the Ethernet port can be used by the embedded application.

DHCP

This switch must be on DHCP position when the FlexMulti device is connected to a LAN to acquire its IP address dynamically from the DHCP server on the network, otherwise the FlexMulti must be configured using a fixed IP address (see section 14).

1, 2, 3 ,4, 5

These five switches are unused.

18 - ARINC 629 RECEIVE-ONLY MODE KEY SWITCH

When the switch is in the horizontal position or removed, there is no ARINC 629 transmission and the unit operates in ARINC 629 Receive-Only mode. When the switch is in vertical position, the ARINC 629 transmission is enabled and the unit operates in both ARINC 629 Transmit and Receive modes.

19 - RESET & FACTORY Reset

This reset switch serves two purposes, to perform a software reset and to perform a factory reset.

To perform a software reset, push and release the reset button. In Ethernet/USB mode, this will cause the device to reset. This reset is inactive in PCIe/PXIe mode.

To perform a factory reset, follow these steps:

1- If the unit is off, turn it on. 2- Hold the reset switch for more than 8 seconds, the power LED will turn yellow and start to blink.


MAX Technologies

3- This process will erase all of the information stored on the device that have been flashed by the user and revert it back to its original settings.

In Ethernet/USB mode, the unit will automatically restart with its original configuration. In PCIe/PXIe mode, the host will need to be shutdown and the power cycle on the device for the changes to take effect.

Communicate with FlexMulti using Ethernet

The FlexMulti device gives you a variety of options to connect to a host computer. The default connection that comes with every device is Ethernet. On the front of the device, you will find a standard RJ45 port. This is a 10/100/1000 Mbps port that has plenty of bandwidth for most applications. To connect, simply use a standard Ethernet cable and connect it to the FlexMulti port as well as your computer or network switch. Ethernet is convenient because of its low cost standard cables and connections as well as great throughput rates. It also allows multiple client applications to connect to the box remotely across the client’s existing IP network.

When connecting the FlexMulti through a network switch, you can use either static or dynamic IP addressing. A static address is assigned by the user or network administrator and does not change. A Dynamic address is assigned by a DHCP server on the client network.

There are two sets of DIP switches on the back of the device. These are used to control the network behavior. On the second set of switches you will see a switch to specify local or remote connection as well activating DHCP.

If the DHCP switch is turned on, the FlexMulti will send out a DHCP request for a dynamic address.

If the DHCP is turned off, then the device will default to static addressing. The default static address subnet is 192.168.0.X, where X is the node identifier of the device. This number is set with the first set of DIP switches. The left most switch is the least significant bit. Use the switches to set the binary representation of the node ID.

When connecting the device directly to a computer without going through a network switch it is essential to use static addressing. In order to communicate, your computer will need to be configured with an address that is on the same subnet as the FlexMulti. In Windows this is accomplished using the Network tools under Control Panel. Right click on the adapter that is connected to the device and then click Properties. From here double-click on TCP/IP.


MAX Technologies

The window that comes up will allow you to switch from DHCP to static. You must enter a unique IP address on the same subnet. For example, if the FlexMulti is using 192.168.0.1, you could use any other address from 2 - 255 on the 192.168.0 subnet. For the subnet mask you must use 255.255.255.0. A default gateway or router address is not needed. Once you configure your settings, simply click ok and close out the other windows. You should now be able to connect to the FlexMulti.

When using a Mac to connect to the device, first click on the apple on the system bar and then click System Preferences. Then select Network. This will show you a list of all network adapters in your Mac. Select the one that is being used and configure the IP address and subnet mask as directed above. You will have to change the setting to Manually unless already selected. You should now be able to connect to the FlexMulti With your Mac.


OSX Network properties

MAX Technologies

You can also connect to the FlexMulti using Linux. Using the terminal commands are the easiest way to configure the IP address for the system. There are some differences between flavors of Linux. If these steps do not work, it is best to consult a system administrator or reference material for your specific installation. The following command will set the IP address and Subnet Mask. Ifconfig eth0 192.168.0.5. Eth0 is the first network adapter in your system. You may need to use eth1 or another one depending on what adapter is connected. Typing in the command ifconfig on it’s own will display a list of all the network adapters in the system.

The default subnet of 192.168.0.X can be changed. If you are working in a network environment that requires static addressing on a different subnet than the default, you must use the flexchangeip command line tool. This tool is available with others in the MX Foundation installation on the computer. Running the command will allow you to specify a new network address for the FlexMulti. Keep in mind the last digits of the address will still be controlled by the DIP switches on the back of the device.
