4: 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 communication 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 communication 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 set up the Comm Port Redirector software:
1
Install the Redirector software from the APS CD. The software and installation
instructions are included on the APS CD.
2
In the Redirector’s configuration screen, select Port Setup and add as many
communication ports as you need (for example, one for each Device Server).
3
Under each port, select Add IP and enter the IP address (Host) of the Device Server
that you want to assign to that port and 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 if you’ve just installed the Redirector, 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
the protocols manuals on
the APS CD).
2
Set the Port Number to a value that is 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.
Note:
When using the Redirector, ensure that the Device Server serial port’s
configuration matches the configuration of your serial device.
