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-HART 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.
