9.1.2 MMT COMMUNICATION VERIFICATION
The MMT Communications Verification test assures that the MMT software is properly communicating
with the ARTU by checking the version of software that is loaded in the ARTU.
Symptom: "ERROR=> MMT communications failure - timed out"
The ARTU and the MMT are not communicating when this information is displayed in the Radio
Responses window. Check the MMT cable connection between the MMT computer and the
ARTU. Check for a damaged connector on RS-232 serial communications port of the computer.
After checking these interface connections press "R" to repeat the test. If the same error is
displayed. cycle power on the computer. If the same error message is displayed after cycling
power on the computer then replace the ARTU.
Symptom: "Radio software executing in unlocked online state"
This message will be displayed on the screen if the ARTU was powered up before the computer
with the MMT software running was connected to the ARTU. Remove power to the ARTU for
greater than 20 seconds. Apply power to the ARTU and press "R" to repeat the test.
