Reverse 12 channel plus busLVDS configuration - do not used this configuration always use the " standard 12"

 

Standard 12 way analogue cable on top SCSI connector, link columns 7-8, 1-2, (all ADC inputs used, Vout from top DAC)

this only leaves busLVDS signals for the bottom SCSI connector, link columns 5-6, 3-4.
