1.4 Setting Jumpers
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.
The following illustration shows the MVI56-104S jumper configuration.
Note: If you are installing the module in a remote rack, you may prefer to leave the Setup pins
jumpered. That way, you can update the module’s firmware without requiring physical access to
the module.
