PLEASE NOTE THE FOLLOWING:

PCIe 1 Lane Cable plugs are keyed with a single groove along one wide
side of the plug. The plug must be inserted into the socket with the
groove aligned properly.

Connect into your Slave Acquisition Modules from the correct channel
groupings on the 9CZi-A Master Control Module; meaning, your first Slave
Acquisition Module is connected from the CHANNEL 1-4 output, second
from the CHANNEL 5-9 output, third from the CHANNEL 9-12 output,
fourth from the CHANNEL 13-16 output, and last from the CHANNEL 17-
20 output.

If you are connecting less than 5 of the Slave Acquisition Modules, the
PCIe 1 Lane Channel Sync Outputs on the back of the Master Control
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.
PCIe 4 Lane Cable - Slave Acquisition Module to Master
Control Module SYNC Connection(s)
Now, let's continue making the PCI Express connections by cabling the PCIe
4 Lane Data Output on the back of each 9xxSZi-ASlave Acquisition Module
to the PCIe 4 Lane Data Inputs on the back of your 9CZi-AMaster Control
Module using PCIe 4 Lane cable(s) provided.
