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-BAS 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.
