Background information: The W&T RS232 Universal Serial T-Switch is an extremely versatile device. Virtually any uni- or bi-directional 2:1 coupling of RS232 devices is possible with this switch.
The Adapter has 3 serial ports: 1 Master port "C" and 2 Slave ports "A" and "B". Each of these ports can be parameterised independently of the others.
The Switch supports 4 data channels (Master C <> Slave A, Master C <> B), which are equipped in each direction with 1 MB buffers. The channels are switched either timed or using control sequences from one of the three Switch ports.
#85643: 3 x RS232 (Port A and B: Female, Port C: Male) #85644: 3 x RS232/422/485 (Port A, B and C: Male) all ports can be configured independently of each other
