Ethernet 1 port
Ethernet 1 was designed primarily for local connection to a computer, such as a
technician's laptop, for occasional maintenance and diagnostic purposes. The connector
is the same RJ-45 Ethernet connector commonly found on most Internet-capable devices.
NOTICE
If your computer is not configured to automatically configure Ethernet settings, contact
your IT department for instructions on how to change your IP settings to an address in the
same range as the Ethernet subnet on the gas chromatograph (GC) or to obtain an IP
address and subnet for the GC that will work with your computer's settings.
If wiring Ethernet 1 to other Ethernet-enabled devices, such as a router, hub, or local
area network, then set the DHCP server switch to OFF to ensure that the operation of the
network is not affected.
