1.4 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.
