Troubleshooting USB Audio Interface Module USB Communication
Issues
If you experience problems with the USB communication between the USB Audio Interface Module
(USB AIM) and MCC 7100 IP Dispatch Console, the issue can be the connection itself or a problem
with the MCC 7100 IP Dispatch Console computer. The symptoms can be the USB AIM indicating the
Link Down or Failure state and the audio malfunction.
Procedure:
Verify the state of the LED indicators on the front of the USB AIM:
If…
Then…
If the green LED flashes
and the red LED is off,
perform the following actions:
a
Verify that the USB cable is properly connected to the USB
AIM and the dispatch console computer.
b
Verify that the dispatch console computer is turned on.
If the green LED is off
and the red LED is on,
verify that the dispatch console is not in the sleep mode.
If you solved the problem by using these verification actions, the green LED is on and the red LED is
off which means that the USB AIM is again online and fully operational. If the USB AIM state did not
change, the problem can be the USB AIM failure.
Postrequisites:
If you did not manage to solve the issue, upgrade the USB AIM software.
Troubleshooting USB Audio Interface Module Upgrade Issues
If you were unable to upgrade the USB Audio Interface Module (USB AIM), the reason can be a lost
USB connection. If you encountered any upgrade issues, use the following scenario to retry to upgrade
the USB AIM software.
Procedure:
1
Unplug the USB cable from the USB AIM and from the MCC 7100 IP Dispatch Console
computer, wait a while, and plug the cable in again.
2
Retry to upgrade the USB AIM software in a typical way.
3
Restart the USB AIM device by unplugging the power supply, waiting a while, and plugging it in
again.
The green and red LEDs on the front of the device are on for a while. Then the red LED goes off
and the green LED stays on.
