Programming the VT1422A & VT1529A/B for Remote Strain Measurement 69
Connecting the VT1529A/B to Strain Gages
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.
