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.
