Telnet Control, Gefen | Gefen EXT-DPKVM-441 specification

TELNET CONTROL

The Gefen 4x1 DPKVM 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 conﬁgured using RS-232 commands. Once properly conﬁgured, 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 conﬁguration.

IMPORTANT: When using HyperTerminal under Windows XP, the LF (line feed) character option must be enabled.

3.Apply power to the Switcher. Information similar to the following will be displayed in the terminal window:
