68-Pin SCSI Connecter (P5)
WARNING !
Avoid redundant connections. Ensure there is no signal conflict between SCSI
pins and the associated header pin (J5. J6. J7. and J8). Also ensure there is no
conflict between TB7 (thermocouple connections) and the SCSI and/or the 40-
pin headers. Failure to do so could possibly cause equipment damage and/or
personal injury.
Pin numbers refer to the 68-pin SCSI female connector, located on the DaqBoard.
