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 MVI69L-MBS jumper configuration, with the
Setup Jumper OFF.
