6. If you are using a DAQ device in your computer to control your
SCXI chassis, connect the mounting bracket of the SCXI-134
x
(where
x
is a number) cable assembly to the back of one of the modules
and screw it into the chassis frame. Connect the other end of the cable
to the DAQ device in your computer. In multiplexed mode, you only
need to cable one module to the DAQ device. In most cases, it does not
matter which module you cable. The following are two special cases
where you should cable a specific module to the device:
a. If you use SCXI-1140 modules with other types of modules, you
need to cable one of the SCXI-1140 modules to the DAQ device.
b. If you use analog input modules and other types of modules, you
need to cable one of the analog input modules to the DAQ device.
7. Turn on your chassis power.
Refer to the

manual for more information about
related topics, such as multichassis cabling.
