RS-422 vs. RS-485 RS-422 is very similar to RS-485; however, RS-422 allows only one Tx on the bus, with a maximum of 10 Rx. This single Tx multiple Rx configuration is called a multi-drop, or broadcast, network. The one driver limitation eliminates the need for a Tx enable pin, which reduces the termination requirement to one 120Ω resistor,
