1. COMPUTER TO RELAY CONNECTION
Connect the SE-135 to the network using a
standard Ethernet patch cable. Use of a crossover
cable to connect the SE-135 directly to the computer
running SE-MON-GFGC is not recommended. A
typical router will assign an IP address to all
connected computers that are using DHCP. The
SE-135 does not support the use of DHCP.
If the SE-135 is being set-up for first time, it is
recommended to only have one SE-135 connected to
the network to prevent communication errors.
