Ethernet (LAN) Port
The rear panel Ethernet connector on the switcher can be connected to an Ethernet
LAN or WAN. Communication between the switcher and the controlling device
isviaTelnet(aTCPsocketusingport23).TheTelnetportcanbechanged,if
necessary,viaSIS.ThisconnectionmakesSIScontroloftheswitcherpossibleusing

of the product are identical to the commands and behavior the product exhibits
when you are communicating with it via a serial port.
