42-Channel RS485/RS422 FMC Module (Vita57.1)
The RS485 standard (TIA-485) specifies
differential data transmission over a terminated twisted pair.. The
standard specifies electrical characteristics of a driver and receiver,
and does not specify any data protocol or connectors. RS485 is popular
for inexpensive local networks, multidrop communication links and long
haul data transfer over distances of up to 4,000 feet. The use of a
balanced line means RS485 has excellent noise rejection and is ideal for
industrial and commercial applications. The RS422 standard is similar to
the RS485 standard but does not permit multiple drivers on a bus.
Similarly, the Profibus (Process Field Bus) protocol uses RS485’s
popular physical medium when deploying fieldbus solutions in factory and
process automation environments.
