Troubleshooting

It's difficult to know what to write here, as there are so many interacting systems. A reasonable procedure is:

1. Set up the codec as you think is correct. Type to the ``tip" window. Check that the send and receive data rates are what you expect, and that the video is looped back correctly.

2. Check that the device driver stats are reporting the correct data rate.

3. With the codec still looped back, run the codec controller and the interface. Check that the indicator is flashing.

4. Set the , even if it says it's correct.

5. By this time you should have and . If you haven't, try pressing . If this still fails, either the codec is in a strange mode, or you've got a device driver that doesn't run properly on your machine.

6. If you have and , then type to the ``tip" window. The lights should go red, as the codec loses sync, but should stabilise green again fairly quickly. If the don't stabilise, it may be worth pressing . It's also possibly the machine's overloaded for some reason. If they both go red and stay red, you should check the codec configuration and data rates again.

7. Set up the codec controller to send and receive from itself. Check that it's receiving it's own data (ie the light is green). You should also see looped back video again.

8. If you've got this far, the codec controller appears to be functioning correctly. Set up the codec controller to and the remote site you want to communicate with. It's important to set the port and ttl before you start sending or receiving, as the change only takes place at start of transmission/reception. Changing packet size however can be done at any time.
