For the SCXI-1190, the maximum rated voltage of the switch is 24 V, and the maximum rated current is 1 A at 24 V. For the SCXI-1191, the maximum rated voltage of the switch is 30 V, and the maximum rated current is 0.33 A at 30 V.
When installing NI-SWITCH, look at the Development Environments panel. • If you click the Advanced button on this panel, you can custom install National Instruments drivers such as NI-DAQ, NI-IVI, and NI-VISA. • If you do not want to install certain drivers, click Advanced and uncheck the driver(s) you do not want installed.
Do not substitute parts or modify equipment. Because of the danger of introducing additional hazards, do not install unauthorized parts or modify the instrument. Return the instrument to National Instruments for service and repair to ensure that its safety is not compromised.
Never touch the exposed pins of connectors. Caution Remove the module from the package and inspect the module for loose components or any sign of damage. Notify National Instruments if the module appears damaged in any way. Do not install a damaged module into your computer.

Make sure the cable between the SCXI chassis and DAQ device or computer-based instrument is properly connected. Inspect the cable and the connectors for any bent pins. Make sure you are using the correct National Instruments cable assembly. Test your DAQ device or computer-based instrument to verify it is working properly.
Your SCXI chassis and/or SCXI module(s) should now be removed from the list of installed devices in MAX. SCXI-1190/1191/1192 User Manual Turn off the SCXI chassis power. Remove all signals connected to the SCXI-119X.
The SCXI-1190 uses single-pole double-throw, high-bandwidth relays capable of switching signals from DC to 1.3 GHz. Functionally identical, the SCXI-1191 has a bandwidth of DC to 4 GHz. The SCXI-1192 module is a general-purpose, 8-channel, high-bandwidth relay module; it uses single-pole double-throw, high-bandwidth relays capable of switching signals from DC to 18 GHz.
