gas chromatograph's (GC’s) wired Ethernet terminal
The Rosemount 700XA has a wired Ethernet terminal at TB11 on the backplane that you
can connect to with a static IP address. All that is needed is a PC, typically a notebook
computer, and a two-wire, twisted pair, CAT5 Ethernet cable with one of its plugs
removed to expose the wires.
