Connecting the NI 9949
Note
National Instruments does not recommend using an RJ-45 cable with the NI 9949
because it can physically damage pins 1 and 10 on the device, and thus permanently
disable shunt calibration no matter what connector you use.
NI 9949 Accessory User Guide

Use an RJ-50 cable to connect the NI 9949 to devices with RJ-50
receptacles, such as the NI 9237 with RJ-50 and the SCXI-1314T. The
NI 9949 routes each pin of the RJ-50 receptacle to the corresponding screw
terminal, where 1–10 represent the pin and terminal numbers and S
represents the shield of the RJ-50 connector. For example, if you connect
the NI 9949 to the NI 9237, pin 1 of the NI 9237 RJ-50 receptacle connects
to terminal 1 of the NI 9949 screw-terminal connector. Refer to Figure 4
for a diagram of the RJ-50 and screw-terminal connectors on the NI 9949.
Refer to the device manual for information about device pin assignments.
