Setting Jumpers

When the module is manufactured, the port selection jumpers are set to RS-232. To use
RS-422 or RS-485, you must set the jumpers to the correct position. The following
diagram describes the jumper settings.
Note: Jumper pin placement on the circuit board may vary.
The Setup Jumper acts as "write protection" for the module's firmware. In "write
protected" mode, the Setup pins are not connected, and the module's firmware cannot
be overwritten. The module is shipped with the Setup jumper OFF. If an update of the
firmware is needed, apply the Setup jumper to both pins.
The following illustration shows the MVI69E-MBS jumper configuration, with the Setup
Jumper OFF.
