SCXI-1314T

[MarkMoss]

I have a number of test stands which use a SCXI-1520 with SCXI-1314T terminal block to measure various bridge-type sensors.  I'm only using this terminal block for the convienence of the RJ-50 connectors, not for the TEDS functionality.  I'm having a bit of trouble getting this setup to work with a third-party LabView RT application which supports the SCXI-1520, but which has not been tested with the SCXI-1314T terminal block.

Figure 3 in the SCXI-1314T manual shows the excitation, bridge output, remote sense, and shunt cal. signals being passed straight through the SCXI-1314T module from the RJ-50 connectors to the SCXI-1520 front panel connector.  Is this always the case?  The application vendor has suggested that the SCXI-1314T may not always pass-through these signals, or may need to be specially configured to do so.

Thanks,

Hello Mark,

When you configure your SCXI-1520 in Measurement & Automation Explorer (MAX) you can also assign an accessory such as the SCXI-1314T to the module.  Since you can also assign an SCXI-1314 as an accessory to the SCXI-1520, you should be aware that the signals in the 1314 and 1314T are different. But, to answer your specific question, yes, the SCXI-1314T always passes the excitation, bridge output, remote sense, shunt calibration, and TEDS data signals from the RJ-50 connectors to the SCXI-1520 front panel connector. Of course, if you do not wire a signal to the RJ-50 modular plug, the signal will not be fed through to the 1520.  If you are having problems, one thing that I would suggest is making sure that the accessory to the SCXI-1520 is actually a 1314T, and not a 1314 in MAX.

Best wishes,
