RS485 Distributor

Model No:RS-104
RS-104 is serial data distributor and similar to a repeaters, gives serial data back on 4 outputs at the same time, allowing perfect configurations. The transmission in RS485 and takes places at the same time on all 4 outputs. The receiving mode of the input can be selected in RS485 or RS232
