connected into DATALINK CHANNEL 1-4, second into the DATALINK
CHANNEL 5-9 input, third into the DATALINK CHANNEL 9-12 input,
fourth into the DATALINK CHANNEL 13-16 input, and last into the
DATALINK CHANNEL 17-20 input.

If you are connecting less than 5 of the Slave Acquisition Modules, the
PCIe 4 Lane Data Inputs on the back of the Master Control Module may
not be skipped and must be connected in consecutive order from the PCIe
4 Lane Data Outputs on the back of the corresponding slaves.
