PMCS supports multiple View Nodes through NetDDE links over a local area
network. Thus, in addition to the PMCS network interface, the Host PC may
also have a LAN interface.
A Host PC with an Ethernet PMCS network interface may use either the same
Ethernet card as the LAN interface or a separate LAN interface card. A Host PC
with an RS485 PMCS network interface requires an additional LAN interface
card to support View Nodes.
Typical LAN interface cards include Ethernet and Token Ring. Any LAN
interface card should be installed according to the manufacturer’s instructions.
