TELNET CONTROL
The Gefen 4x1 DisplayPort Switcher supports Telnet for controlling the Switcher
over a network. To access this feature, an IP address, subnet, gateway, and port
numbers need to be set correctly. Consult the network administrator to obtain the
proper IP address and settings for this product to properly communicate with the
Switcher over a network.
The Telnet control must be confi gured using RS-232 commands. Once properly
confi gured, enter the IP address that was assigned to the Switcher using a
terminal program or other Telnet client.
1. Connect the Switcher to a computer using RS-232.
2. Use a terminal emulation program (e.g. HyperTerminal, PuTTY, Indigo,
etc.) to connect to the Switcher. See page 14 for information on RS-232
confi guration.
3. Apply power to the Switcher. Information similar to the following will be
displayed in the terminal window:
