Step 8. Connect the Modules to the DAQ Device
Single-Chassis System
If you installed modules in a PXI/SCXI combination chassis, the PXI backplane of the chassis connects
the modules and DAQ device.
If you are using an SCXI chassis, complete the following steps:
1. Connect one end of the 68-pin shielded cable to the SCXI-1349.
2. Connect the other end of the cable to the DAQ device. For M Series devices, connect the cable to
connector 0.
If you are running modules in parallel mode, repeat the steps for each module and DAQ device pair.
Multichassis System
1. Connect one end of a 68-pin shielded cable to the E or M Series DAQ device.
2. Connect the other end of the cable to the SCXI-1346 in chassis ID n labeled FROM DAQ BOARD
OR PREVIOUS CHASSIS.
3. Connect a 68-pin shielded cable to the SCXI-1346 in chassis n labeled TO NEXT CHASSIS.
4. Connect the other end of the cable to the SCXI-1346 in chassis ID n+1 labeled FROM DAQ
BOARD OR PREVIOUS CHASSIS.
5. Repeat steps 3 and 4 for the remaining chassis until you reach the last chassis.
6. Connect the 68-pin shielded cable to the next to the last chassis in the slot labeled TO NEXT
CHASSIS.
7. Connect the other end of the cable to the SCXI-1349 in the last chassis.
