1.3 Setting Jumpers
If you use an interface other than RS-232 (default), you must change the jumper
configuration to select the interface you wish to use. There are three jumpers located at
the bottom of the module.
The following illustration shows the MVI56-DFCM jumper configuration:
1 Set the PRT 2 (for application port 1) and PRT 3 (for application port 2) jumpers
select RS232, RS422, or RS485 to match the wiring needed for your application. The
default jumper setting for both application ports is RS-232.
2 The Setup Jumper acts as "write protection" for the module’s flash memory. In "write
protected" mode, the Setup pins are not connected, and the module’s firmware
cannot be overwritten. Do not jumper the Setup pins together unless you are directed
to do so by ProSoft Technical Support.

1.4 Installing the Module in the Rack
If you have not already installed and configured your ControlLogix processor and power
supply, please do so before installing the MVI56-DFCM module. Refer to your Rockwell
Automation product documentation for installation instructions.
Warning: You must follow all safety instructions when installing this or any other electronic devices. Failure
to follow safety procedures could result in damage to hardware or data, or even serious injury or death to
personnel. Refer to the documentation for each device you plan to connect to verify that suitable safety
procedures are in place before installing or servicing the device.
After you have checked the placement of the jumpers, insert MVI56-DFCM into the
ControlLogix chassis. Use the same technique recommended by Rockwell Automation
to remove and install ControlLogix modules.
Warning: When you insert or remove the module while backplane power is on, an electrical arc can occur.
This could cause an explosion in hazardous location installations. Verify that power is removed or the area
is non-hazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both
the module and its mating connector. Worn contacts may create electrical resistance that can affect module
operation.
1 Turn power OFF.
2 Align the module with the top and bottom guides, and slide it into the rack until the
module is firmly against the backplane connector.
3 With a firm but steady push, snap the module into place.
4 Check that the holding clips on the top and bottom of the module are securely in the
locking holes of the rack.
5 Make a note of the slot location. You must identify the slot in which the module is
installed in order for the sample program to work correctly. Slot numbers are
identified on the green circuit board (backplane) of the ControlLogix rack.
6 Turn power ON.
Note: If you insert the module improperly, the system may stop working, or may behave unpredictably.
