1.4.1 Setup Jumper
The Setup Jumper acts a write protection for the module's firmware. In "write-protected"
mode, the setup pins are not connected which prevents the module's firmware from being
overwritten.
The module is shipped with the Setup Jumper OFF. If you need to update the firmware or
run a module rescue (recovery), apply the setup shunt over both pins.
1.4.2 Port 1 and Port 2 Jumpers
These jumpers, located at the bottom of the module, aid in configuring the port settings to
RS-232, RS-422, or RS-485. The "RS-232", "RS-485", and "RS-422" labels are there for
convenience. The jumpers simply send a high/low signal when jumped or not jumped. The
jumper configuration is read by the API, and the application code must change the
appropriate port settings to the required mode (232, 485, 422).
1.5 Installing and Connecting the Module
If you have not already done so, please install and configure your CompactLogix processor
and power supply. Refer to the 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 this device.
After verifying proper jumper placement, insert the module into the CompactLogix chassis.
Use the same technique recommended by Rockwell Automation to remove and install
CompactLogix modules.
