7.4 Wiring

Attach the sensor cable to the six-pin male connector on the 020C. Make sure
the connector is properly keyed. Finger-tighten the knurled ring. Route the
sensor cable along the underside of the crossarm to the tower, down the tower,
and to the instrument enclosure. Secure the cable to the crossarm and tower
using cable ties.

The cable consists of five wires. Wiring for specific Campbell Scientific
dataloggers is shown in Table 7-1.
