How do I perform a Loopback test using the Config Utility for ConnexLink RS-232 after successfully reading the radios?

From the 9 pin serial, pins 2 and 3 need to be connected. These are the Tx and Rx pins.

Go to “Range Test” tab -> “Port 1 Loopback”.

Using the default values select the “Run” button.  

Good test results should return 0-9, A-Z, and a-z in the “View TX/TX Packet” box and “Test Result”. Bad test results return errors.
