Jumpers

The following illustration shows the jumper configurations for the various RS
interfaces. If you are using an interface other than RS-232 (default), you must
change the jumpers as shown:

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.
