Connecting the SCXI-1125 in a PXI/SCXI Combination Chassis to an
E/M/X Series DAQ Device for Multiplexed Scanning
Refer to the
SCXI Quick Start Guide
to connect the SCXI modules to the
DAQ device.
If you have already installed the appropriate software, refer to Chapter 3,
, to configure the SCXI-1125 module(s).
Connecting the SCXI-1125 to an E/M/X Series DAQ Device for
Parallel Scanning
This configuration allows you to route all eight channels of the SCXI-1125
in parallel to eight input channels of the E/M/X Series DAQ device to
which it is connected. In this mode, you cannot directly access the CJC
channel. Use this mode if you require a higher scanning rate than an SCXI
system in multiplexed mode allows.
Note
You can also use the SCXI-1125 with an S Series DAQ device in parallel mode.
If you have not already installed all the modules, refer to the
SCXI-1125 Module into the SCXI Chassis
section, then complete the
following steps:
1.
Power off the SCXI chassis and the computer that contains the
E/M/X Series DAQ device.
2.
Insert the cable adapter into the rear of the SCXI-1125 module that is
to be accessed in parallel mode by the E/M/X Series DAQ device.
Refer to the installation guide for the 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 E/M/X Series DAQ device
that you want to use to access the SCXI-1125 in parallel mode.
5.
Connect additional SCXI-1125 modules intended for parallel mode
operation by repeating steps 2 through 4.
6.
Check the installation, making sure the cable is securely fastened at
both ends.
7.
Power on the SCXI chassis.
8.
Power on the computer.
