How to configure the IOLAN+ to perform a similar function as a matrix switching box.

Solution:

The following configuration will allow you to open many Telnet windows from a direct attached PPP Client. Each Telnet connection will be made to a specific serial port on the IOLAN+ to allow you to communicate with the serially attached device.

1. Connect a Windows PC to Port 1 on the IOLAN+.

2. Connect serial devices to Port 2, Port 3 and Port4. These will be devices you wish to communicate with. For example, it could be the serial console port of a router, or the serial port of another IOLAN+,...

3. Configure your Windows PC for Dial-up networking so you now have a WIndows PPP client.

4. On your PC, install a null-modem (inf) driver software. This will allow you to connect your PC directly to the IOLAN+ serial port using a cross-over cable, thus eliminating the use of modems.

5. On the IOLAN, configure Port 1 with Access [PPP]

6. On the IOLAN, configure Port 2, Port 3 and Port 4 with Access [Remote] and Mode [Telnet]. Save and exit the ports. Kill the ports for changes to take effect.

7. From the Windows PPP Client, open a Telnet session to the serial port you wish to connect to. For example,

This is the Telnet command: telnet <IP address of IOLAN> <local port number>

For example, suppose the IP address of the IOLAN was 192.65.146.7

Local port number for Port 2 is 10002,

Local port number for Port 3 is 10003.

Local port number for Port 4 is 10004.

Therefore,

To connect to a serial device that is attached on Port 2, type:

telnet 192.65.146.7 10002

To connect to a serial device that is attached on Port 3, type:

telnet 192.65.146.7 10003

To connect to a serial device that is attached on Port 4, type:

telnet 192.65.146.7 10004

and so on,...
