TROUBLESHOOTING INSTRUCTIONS FOR USB TO RS232 CONVERTER

1) Driver installation
USB rs232 cable driver installation

Make sure that the USB-232-1 is connected to your USB port, and the driver is installed correctly (as shown above); otherwise, please reinstall the drivers.

2) Make sure the “Power” LED on USB-232-1 is lit up.

3) Loopback Test

  • Connect pin 2 and 3 of the DB-9 connector (as shown above).
  • Run 232Analyzer FREE version software on your computer.
  • Select "ASCII" for both the Send and Receive data formats. Then send command and/or string such as "CommFront" from the 232Analyzer software. You should receive an echo of the command/string sent ("CommFront"). By performing a simple loopback test like this, you can test both the transmitter and receiver of the converter. This is very helpful when you are in doubt about the performance of your converter.
