There are currently two ways to interface the NI 9237 4-Channel Bridge Module to a strain gage.
1.) RJ50 10-pin Modular Plug to DB-9 (Male), 1m, part number: 192190-01
2.) Connecting the strain gauge signal wires through a RJ-50 (10p10c) modular plug
the SCXI -1314T TEDS Bridge Sensor Terminal Block Installation Guide
contains a section on connecting the signals wires to the modular plug
in the section "Channel Signals" on page 6.
You can also connect the 9944 to the RJ-50 using the SCXT 1314T. Strain Gauge>9944 quarter bridge>RJ 50 pigtails>1314t's. Is there any particular reason that you are trying to use the 9237 and the 9944? What other hardware do you have for this application?
