Connecting The Scxi-1125 To A Daq Device For Multiplexed Scanning In An Scxi Chassis - National Instruments SCXI-1125 User Manual

Connecting the SCXI-1125 to a DAQ Device for Multiplexed Scanning in
an SCXI Chassis
© National Instruments Corporation
This configuration allows you to multiplex all eight input channels and the
CJC channel of the SCXI-1125 into a single channel of your DAQ device.
You need the following items for this installation:
• SCXI chassis with the SCXI modules installed
• SCXI cable assembly, which consists of a cable adapter and a cable
• An installed National Instruments DAQ device
• 1/4 in. flathead screwdriver
Consult your SCXI chassis documentation, other SCXI module
documentation, and DAQ device documentation for additional instructions
and warnings. Your SCXI-1125 module and any other SCXI modules
should already be installed in the chassis according to their installation
instructions. You must select one of the analog input modules in the chassis
to be the "cabled" module, the module to which the SCXI cable assembly
will be connected. If the chassis contains at least one SCXI-1140 module,
select an SCXI-1140 to be the cabled module; otherwise, select one of the
remaining analog input modules. To connect the chassis to a DAQ device
for multiplexed operation, complete the following steps while referring to
Figure 1-3:
1. Turn off the SCXI chassis and the computer that contains the DAQ
device.
2. Insert the cable adapter into the back of the SCXI chassis aligned with
the module that is to be connected to the DAQ device. See the
installation guide for your cable assembly for more information.
3. Connect the cable to the back of the cable adapter ensuring that the
cable fits securely.
4. Connect the other end of the cable to the DAQ device that you will use
to control the SCXI system.
5. Check the cable installation, making sure the connectors are securely
fastened at both ends.
6. Turn on the SCXI chassis.
7. Turn on the computer.
8. If you have already installed the appropriate software, you are ready to
configure the SCXI-1125(s) for multiplexed mode operation. See
