Frequently Asked Questions
Question 30: HOW DO I PERFORM A LOOPBACK TEST FOR MY RS-232 / RS-422 CONVERTER?
Answer: Performing a Loopback Test is easy with Hyperterminal software. Simply connect TX+ and TX- to RX+ and RX- respectively and connect the RS-232 / RS-422 converter to your PC's COM port. Send characters in Hyperterminal and you should receive an echo of those characters. By performing a simple Loopback Test like this, you can test both the Transmitter and Receiver of your RS-232 / RS-422 converter, which is very helpful when you have questions about the performance of your converters or cables.
