3.1.7. b2826 Problems with USB LTC Widgit.

Name: Justin
Date: Oct.16.2010
Software Version and build number: 3.1.7 b2826
Number of external displays:2
Connected USB Devices: USB LTC Widgit
Networked Devices: 2 - DP2000
Detailed description of the problem:

Upgraded from version 2.3.0 software on the hog 3. After managing to complete the upgrade i noticed problems with the LTC Widgit in regards to receiving Time code. It would work just after booting up the board, but then after a while of not receiving code it seemed to not acknowledge when code was being run again. Ended up running the show manually and then rolled back to 3.1.5. Everything seems to be running fine now.

    It sounds like like your timecode input signal is marginal. It may have lot of noise in it, or the signal level could be too high, or too low. Also make sure the timecode isn't going through any kind of audio processing (compressor/limiter, EQ, etc.).

    You said the timecode doesn't run smoothly in the time code toolbar. That means the console is getting a valid timecode update every once in a while, but it's choppy. Timecode is a constant signal. The audio feed is sending 1, 2, 3, 4, 5... But the console is hearing something like noise, 2, noise, 5, noise, 8. The console does its best to fill in the gaps, but if the updates are noisy enough it will eventually give up.

    You can try increasing the "Regenerate Frames" value to try and run through the gaps, but this will only mask the symptoms, the underlying signal problem is still there. Work with the timecode signal until the toolbar runs smoothly and the forward LED is on solidly.
