A.1 Diagnosing Problems Using the Included Software
Using the included software and following these simple steps can eliminate most
common problems.
1. If your adapter isn’t working, first check to make sure that USB support is
enabled in the System BIOS and it is functioning properly in the operating
system. This can be done by using either the Windows 98/Me or Windows
2000 Device Manager.
2. Make sure that the IC162A software has been installed on the machine so that
the necessary files are in place to complete the installation.
3. When the IC162A is configured properly, you can use the WinSSD utility and a
loopback plug to check communications. You can make a simple loopback in
the field by connecting the TX and RX pins. If you decide to test the modem
control signals, a full pin loopback plug will be required. Details on loopback
plugs are included within WinSSD.
4. When testing the IC162A in loopback mode, you should see both the TD and
RD echoed as data on the screen. The loopback test first transmits a HEX
pattern, 55AA, and then an ASCII string of data. If this test passes, then the
IC162A is ready for use in your application.
5. Always use the diagnostic software when troubleshooting a problem. This will
eliminate any software issues from the equation.
If these steps do not solve your problem, contact Black Box Technical Support at
