    Advanced Operation RS-232 and IP Configuration IP Configuration The 4x1 DPKVM Switcher supports also IP-based control using Telnet. To set up IP control, the network settings for the 4x1 DPKVM Switcher must be configured via RS-232. The default network settings for the switcher are as follows: Description IP Address / Port Description IP Address / Port 192.168.1.72 IP Address Telnet Port 255.255.255.0 Subnet 192.168.1.254 Gateway HTTP Port Connect an RS-232 cable from the PC to the 4x1 DPKVM Switcher. Also make sure that an Ethernet cable is connected between the switcher and the network. Launch a terminal emulation program (e.g. HyperTerminal) and use the RS-232 settings listed on the previous page. NOTE: Depending upon the network, all related IP / Telnet settings will need to be assigned. Consult your network administrator to obtain the proper settings. Set the IP address for the switcher using the #sipadd command. Set the subnet mask using the #snetmask command. Set the gateway (router) IP address using the #sgateway command. Set the Telnet listening port using the #set_telnet_port command. Set the HTTP listening port using the #set_http_port command.
