Frequently Asked Questions

Question 31:  HOW DO I PERFORM A LOOPBACK TEST FOR MY RS-232 / TTL CONVERTER?

Answer: Perform a Loopback Test with a Hyperterminal software.  Connect TX (TTL out) to RX (TTL in) and then send commands from the Hyperterminal software, you should receive an echo of the commands sent.

By performing a simple Loopback Test like this, you can test both the transmitter and receiver of your RS-232/TTL converter, which is very helpful when you are in doubt about the performance of your converter.
