1.3 Setting Jumpers
If you use an interface other than RS-232 (default), you must change the jumper
configuration to match the interface. The following illustration shows the MVI46-
MCM jumper configuration:
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.
