TESTING THE INSTALLATION
To fully test the installation of your Fastcom: 422/X-PCIe, you will need to build a "loop back plug". Materials
needed are a DB9 male plug, solder-cup style, and two short pieces of 20 or 24 AWG stranded wire. This loop
back plug can be used to test any RS-422 port. Jumper the pins together on the DB9 as illustrated below:
Pin 4 Tx +
Pin 5 Tx -
Pin 8 Rx +
Pin 9 Rx -
These instructions assume that you have already installed the card and have followed the installation instructions.
The Device Manager should show the boards/ports that are installed.
1. Attach the cable assembly to the card and then the loop back to the end of the cable assembly.
2. Open a command prompt (Click Start->Run-
>type “cmd”->click OK) and change to the directory
where you copied the
422/X-PCIe
software.
3. Change to the test directory (serialfc\test\).
4. Run the included test program on a port:
a. # test 3
The output will look something like this:
