5.4.12 Communications
The Rosemount 700XA has four serial communication ports: Port 0, Port 1, Port 2, and
Port 3, which is a dedicated personal computer (PC) to gas chromatograph (GC) port.
You can set the mode for each of the first three ports to RS232, RS422, or RS485.
Normally, the customer specifies these port configurations at the time of order, and
Emerson sets them at the factory. However, the customer can use Rosemount MON2020
to change them at any time.
Note
The backplane has two switches located at SW1. The first switch is used for starting the
DHCP server. The second switch is reserved for future use.
The backplane has two Ethernet ports:
