Fiber Repeater Mode
When a distance that is more than 5 km (3.1 mi) has to be supported, iSC2F must be used in
Fiber Repeater mode. This mode supports extended distance between serial devices.

The repeat function will optically re-transmit any data received on the optical receiver, in
addition to any connected serial devices. As a result, any data transmitted from the master,
will be re-transmitted optically to the slave. In this case, the distance between master and
slave can be extended over the 5 km (3.1 mi).
This topology can be used for RS232, RS485 or RS422. In all cases, all repeater devices should
have the repeat function—DIP position 5 ON.
