How to connect 2-wire strain gage to NI 9237 by quarter bridge

[Burzredion]

I have a Strain Gage: KYOWA KFG-20-120-C1-11 (2 wire) http://www.kyowa-ei.co.jp/english/products/gages/pdf/kfg-01.pdf, NI 9237 on a Compact DAQ (cDAQ 9174) and RJ-50 (10-pin modular plug to pigtail wires).

Strain Gage features:

Gage Factor: 2.08 +/- 1.0%

Gage Resistance: 120.2 +/- 0.2 Ohms

I'd like to connect them to measure the strain with quarter bridge configuration but I have some doubts about which line goes to which terminal.

Thanks.

You can find the manual for the NI 9237 module here

It's a good idea to buy an NI 9944 or NI 9945 Quarter Bridge Completion Accessory if you're planning on using this module with a quarter bridge configuration, but  you can look at the following diagrams to see what kind of internal connections are implemented: Connecting Strain Gauges and Shunt Resistors to the NI 9237

PS Posting in the DAQ or signal conditioning forums instead of Labview may get you better/faster answers. 

Cheers
