The following discussion relates to the connection marked "C" in Figure 3-1
on page 58. Connecting the strain gages to the RJ-45 telecom connectors is
illustrated below. These connections can be made with the same type of
cable and crimp-on connectors used for Data Interface connection
(connection "A" in Figure 3-1). See Figure 3-8 for a gage connection example.
RJ-45 Modular Connector (Shielded)
8-Conductor Twisted-Pair, Overall-Shielded
(Probably Stranded for Flexability)

Figure 3-9 shows the pin-to-signal relationship for each VT1529A/B strain
gage connector. The same signal names are found on the following strain
bridge configuration illustrations as well.
