Termination can be activated by jumper.A 2 pin terminal block on the transition module can be used to provide +5V to the RJ45 connectors (pin 1) of channel 3 to 8 and to supply the on board termination for RS422/ RS485. Support of the +5V is selectable by jumper. The +5V is fuse protected by a 1A multi-fuse.
