RMC30
The diagram:
illustrates a topology that utilizes the RMC20 repeat
mode function. The repeat function will optically retransmit 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 retransmitted optically to all the slaves.
This topology can be used for RS232, RS485, or RS422 multi-drop networks. In all cases, all
slaves have the repeat function (DIP position 4) ON, while the one connected to the RMC30 is
configured with the repeat function OFF. The port used on the RMC30 must be in full-duplex
mode, while the ForceHD (Force Half-Duplex) parameter must be turned ON.
