chassis according to their installation instructions. To connect the
SCXI-1141/1142/1143 module with a DAQ device in a PXI combination
chassis for multiplexed scanning, follow these steps:
1.
No cables are required for this connection if the National Instruments
PXI DAQ device is installed in the right-most slot. You can configure
this device to control the SCXI system. If the DAQ device for
controlling the SCXI system is not installed in the right-most slot of
the PXI combination chassis, configure the system as described earlier
in the
Connecting the SCXI-1141/1142/1143 Module to a DAQ Device
for Multiplexed Scanning in an SCXI Chassis
section.
2.
Turn on the SCXI chassis.
If you have already installed the appropriate software, you are ready to
configure the SCXI-1141/1142/1143 module for multiplexed scanning. See
the
Configuring and Testing the SCXI-1141/1142/1143 Module
section
later in this chapter for information on configuring and testing the
installation.
Connecting the SCXI-1141/1142/1143 Module to a DAQ Device for
Parallel Scanning
Use this configuration to route all eight channels of the
SCXI-1141/1142/1143 module in parallel to eight input channels of the
DAQ device with which it is connected. You can use this mode if you
require a higher scanning rate than the SCXI system allows in multiplexed
mode. You need the following items to complete this installation:
•
SCXI chassis or PXI combination chassis with the
SCXI-1141/1142/1143 module(s) installed
•
For each SCXI-1141/1142/1143 module operating in parallel mode,
you need one each of the following:
–
National Instruments DAQ device
–
SCXI cable assembly, which consists of a cable adapter and a
cable
•
1/4 in. flat blade screwdriver
