The customer ordered his own cable, incorrectly wired for Tascam. I need to modify it, today, to finish this upgrade. I found the pinout on Yamaha's site. The card is in an M7, it is the AES 4 in 4 out card.
But: There are only 7 pins for the 8 shields.
And: which of the 8 channels are in and which are out? 1-4 and 5-8 or the reverse, or in pairs 1/2, 3/4, etc?
