on the front panel. For information on this port, see “

LAN connector — Plug an RJ-45 network cable into this
connector to connect the unit to a network (via a switch,
hub, or router) or to a single computer.
Activity LED — This LED blinks to indicate network
activity.
Link LED — This LED lights to indicate a good network
connection.
Use a straight-through cable to connect to a network, or a crossover cable to
connect directly to a computer.
• For 10BaseT (10 Mbps) networks, use a CAT 3 or better cable.
• For 100BaseT (max. 155 Mbps) networks, use a CAT 5 cable.
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

Commands” in the “Command/response table for IP SIS commands” in
chapter 4, “Software Conguration and Control”) or by using the Comm./
IP Configuration menu on the front panel (see “Comm./IP Configuration
menu” in chapter 3). The LAN port defaults are:
IP address: 192.168.254.254
•
Gateway IP address: 0.0.0.0•
Subnet mask: 255.255.0.0•
DHCP: off•
