groove aligned properly.


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