Re: CMI III error : No CMI31 Channel cards connected

2010-07-05 by horiprod

Hi Arron.

The CMI does a real basic hardware check of channel cards through the motherboard. However, all the timing clocks for the channels come from the aptly named channel support card, CMI 32. If you can't substitute a known good replacement, check the master clock on this, and then the two delay chips which provide the timing signals. Sorry can't remember what they're called - still on holiday, and spent the evening in a canal side bar in East London drinking the finest wines known to humanity.....

Regards,

Peter Wielk
