SCXI USB Modules
SCXI USB modules are plug-and-play, integrated signal conditioning modules that communicate
between an SCXI system and a USB-compatible computer or USB hub, so no intermediate DAQ device
is needed. SCXI USB modules, such as the SCXI-1600, cannot be used in a PXI/SCXI combination
chassis or in multichassis systems. After you install the module in the chassis, complete the following
steps:
1.
Connect the USB cable from the computer port or from any other USB hub to the USB port on the
SCXI USB module.
2.
Attach the cable to the strain relief using a cable tie.

Adding a Module to an Existing SCXI System
You also can add a module to an existing SCXI system in multiplexed mode. If your system already has
a controller established, you can simply install additional SCXI modules in any available chassis slots
as previously described. Refer to the list of SCXI modules in
determine which module to connect to the cable adapter, if applicable.
