Question 26: How do I perform a Loop back Test for my RS-232/RS-485 converter?
Answer: Connect two RS-232/RS-485 converters to your PC's COM ports (if your PC does not have enough COM ports, you may use USB to RS-232 converters or cables). Run two instances of 232Analyzer software on your PC. When you send commands (i.e. "CommFront" in ASCII format) from one COM port, you should receive the same commands on the other, and vice versa.
By performing a simple Loop back Test like this, you can test you RS-485 transceiver, which is very helpful when you are in doubt about the performance of your converters or cables.
