8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control

3.2.12.2 IP Configuration through port 23

If you were unable to enter the IP setting mode through the serial command, a Telnet TCP programming method can be used to turn on RS-232 serial mode programming, or even to configure the network settings directly through port 23.

To open a Telnet section, a command prompt (Run: CMD) or a HyperTerminal window can be used:

For example, to run a HyperTerminal window, set it up for TCP/IP connection on PORT 23 along with the Matrix’s default IP address as the host address.

Telnet commands and replies have the following format:

STX

Command/reply

CR

•STX character (ASCII code 2 or CTRL-B from the keyboard) The unit will respond with <CTRL-B> A for most valid commands.

1.To use the IP configuration Telnet commands, you must first log in using the

(L) command.

Command: <CTRL-B> L <CR> stands for Log in

2.To enable a serial IP setting (serial programming) mode, type the following commands:

Command: <CTRL-B> SSE2 <CR> Stands for Set Serial Enable

Command: <CTRL-B> SEC6 <CR> Stands for Serial Enable Char

Command: <CTRL-B> O <CR> stands for log out

Reboot the system by cycling power. Now you should be able to configure IP parameters through the IP port.

Alternatively instead of rebooting the system you could use <CTRL-B> <E> <CR> to reboot the IP port, this may cause a momentary loss of Telnet connection.

3.To get the current IP address:

Command: <CTRL-B> GIP <CR>

Response: <CTRL-B> A 192.168.123.180 <CR>

4.To set a new IP address:

Command: <CTRL-B> SIP192.168.123.179 <CR>

5.To get the current gateway IP address:

Command: <CTRL-B> GGI <CR>

Response: <CTRL-B> A 192.168.123.122 <CR>

6.To set a new gateway IP address:

Command: <CTRL-B> GGI192.168.123.125 <CR>
