National Instruments SCXI-1346 Multi-Chassis Cable Adapter

The SCXI-1346 (Part Numbers: 776574-46, 182543C-01) is meant for applications involving multi-chassis SCXI because it can join them to one DAQ device. This Cable Adapter has two cable connections. One connection is for signals from the digitizer or a former SCXI chassis, while the second connection is used to route the digitizer’s signals to the subsequent chassis. The SH68-68-EP (Part Numbers: 184749-01, 1 m cable; 184749-02, 2 m cable; 184749-05, 5 m cable; or 184749-10, 10 m cable) can be purchased separately and used with the NI SCXI 1346. This Cable Adapter has a mounting bracket for dependable attachment to the SCXI chassis.

The SCXI 1346 has four connectors. The first connector is a 68-pin male connector on the front panel with To Next Chassis printed on it. The next connector is another 68-pin male connector on the front panel with From DAQ Board or Previous Chassis printed on it. The third connector is a 50-pin male breakout connector on the printed-circuit board. The last connector is also a 50-pin connector but is a bracket-mounted female on the back of the Cable Adapter.

To utilize the NI SCXI 1346 in a multi-chassis system, these items are required: a computer, a small flathead screwdriver, 68-pin shielded cables, a 68-pin E Series DAQ device, an SCXI 1001 or SCXI 1000 Chassis (revision K or higher), one or more SCXI module for each chassis (with the exception of the SCXI-1127, SCXI-1190, and SCXI-1191), the SCXI 1349 shielded cable assembly, and the SCXI-1346 Installation Guide. The user should keep in mind not to use more than 10 m cable length overall in a multi-chassis SCXI system. This will help ensure dependable operation.

The SCXI 1346 is run using the NI-DAQmx driver software which is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows, LabVIEW SignalExpress, Measurement Studiio, Visual C++, or Visual Basic. The device hardware can be configured using the National Instruments Measurement & Automation Explorer (MAX) tool.

SCXI 1346 Obsolete Status has been announced by National Instruments, but the Cable Adapter will still be available for purchase and repairs by Apex Waves.
