6.5. Termination
When putting devices on the ModBus network, a terminating resistor may be
required for the last device on the network (please see www.modbus.org for more
details). The
has a blue jumper on the “public” jumper that can be used
to jumper in a 120-Ohm terminating resistor. By default, this jumper is not in
place. Oldham does not recommend changing the placement of any of the other
jumpers on this board.
