Simplex/Transmit, Receive Only
Simplex configuration means that more than two devices can be linked all together to
communicate through many IC485S / GB / EU devices. Its configuration is like the
Multidrop’s, but the master device can talk only and the slave devices can listen only.
Note: Bn means any one of the B1, B2, B3 and so on.
