RS-485, like RS-422, can be made full-duplex by using four wires. [8] Since RS-485 is a multi-point specification, however, this is not necessary or desirable in many cases. RS-485 and RS-422 can interoperate with certain restrictions. [9] [failed verification]
The AISG bus is a single master multi slave bus. Communication media can be either RS-485 based using a dedicated cable specified in the AISG standard or OOK carrier injected into the RF antenna feeder cable of a base station site. The master controlling the communication is called a primary and the slave devices on the bus are called ...

When used in relation to communications wiring, RS-422 wiring refers to cable made of 2 sets of twisted pair, often with each pair being shielded, and a ground wire. While a double-pair cable may be practical for many RS-422 applications, the RS-422 specification only defines one signal path and does not assign any function to it.
DMX512 electrical specifications are identical to those of the EIA-485-A standard, except where stated otherwise in E1.11 [example needed]. DMX512 is a bus network no more than 400 metres (1,300 ft) long, with not more than 32 unit loads (individual devices connected) on a single bus.
MIL-STD-1553B does not specify the length of the cable. However, the maximum length of cable is directly related to the gauge of the cable conductor and time delay of the transmitted signal. A smaller conductor attenuates the signal more than a larger conductor. Typical propagation delay for a 1553B cable is 1.6 nanoseconds per foot.
