network, which sometimes is called a ring. The EIA/TIA RS-485 communications standard supports up
to 32 devices (driver/receiver pairs) on a cable of up to 4,000 feet. The EVM-IPVS-16A network module
has two RS-485 ports, supporting up to 64 devices. The EVM-IPVS-16A network module typically acts
as the master for each of the two RS-485 networks.
