68-pin SCSI connector differential and single-ended pin outs (P5)
The 68-pin SCSI connector provides 16 single-ended analog channels or eight differential analog channels.
Refer to the "40-pin header connector pin outs" section starting on page 16 to learn the pin outs for accessing up
to 64 single-ended/32 differential analog channels using the P5 and P6 connectors.
Caution!
Avoid redundant connections. Make sure there is no signal conflict among the SCSI pins, the 40-
pin header connector pins (J5 - J8), and the TB7 TC connections. Failure to do so could possibly
cause equipment damage and/or personal injury.
