8: Using the Device Server
Comm Port Redirector
The Lantronix Comm Port Redirector application allows PCs to share modems and other
serial devices connected to a Device Server using Windows-based applications.The Comm
Port Redirector intercepts communications to specified COM ports and sends them over an
IP network connection to the Device Server’s serial port. This enables the PC to use the
Device Server’s serial port as if it were one of the PC’s COM ports. Using their existing
communications software, users can dial out to a remote host through a modem connected
to the Device Server.
Redirector Setup
To setup the Comm Port Redirector software:
1 Install the Redirector software. The software and installation instructions are
included on the distribution CD.
2 In the Redirector’s configuration screen, select Port Setup and add as many COM
ports as you need (for example, one for each Device Server).
3 Under each port, select Add IP and enter the IP address (Host)oftheDeviceServer
that you want to assign to that port, and then enter the TCPPort number (3000 to
3009).
Note: Remember the TCPPort number. You will need it to configure the
Device Server.
4 Save the configurations and reboot your PC.
Device Server Configuration
The following procedure should be repeated for each Device Server defined in the
Redirector setup, above.
1 Enter the Device Server’s Setup (configuration) Mode (see Chapter 7).
2 Set the Port Number to 11000 higher than the TCPPort number selected in the
Redirector setup above (for example, if the TCPPort number was 3005, set the
Device Server’s Port Number to 14005).
3 Save the configurations and exit Setup Mode.
