it isn't scsi. First of all it is a Pro-Log STD bus card. The card is an analog to digital and digital to analog convertor. The ad667 chips are 12 multiplying digital to analog convertors which gives you four analog outputs for the board. I couldn't make out the Burr-Brown part numbers, but I suspect that they are sample and hold amplifiers or analog switches that take eight analog inputs and presents them to the TSC800 chip which is a 15 bit analog to digital converter. Just a guess anyway... best regards, Steve Thatcher At 08:32 PM 09/08/2004, you wrote:
