Configuring NI9219 for strain measurement

Question

Hi!
I am trying to set-up a strain measurement VI using Labview. I am using NI 9219 module on NI cDAQ 9172 chassis.  My strain gage is configured in a quarter-bridge arrangement and I have made strain gage connection accordingly (to terminals 3 & 5 in NI 9219). However, I do not understand what are TEDS terminals for and what to connect to those terminals. Can I use virtual TEDS for this? I couldn't find a virtual TEDS for NI 9219. Any information in resolving this issue would be highly appreciated.
Best,

Hi, the TEDS terminals are only for transducers, like a strain gauge, that support TEDS (Transducer Electronic Data Sheet).  The TEDS standard is just the ability of a transducer to save information about itself in internal memory.  This information includes things like calibration constants and dates, scaling factors, electrical characteristics, etc.  It is stored in a standard template which can be read by computers and DAQ cards via those TEDS lines.  For you application, you should just leave them unwired, and setup up your strain gauge normally.
