Step 4 – Connect SmartSensor Cable

The sensor connector as shown in Figure 5 a. is keyed such that it can only fit one way. Attach it

to the coupling at the base of the sensor. The cable should be strapped to the pole or run through

conduit to reduce the strain on the cable.

Figure 5

a. Sensor Connector b. Service End

The service end of the cable (Figure 5 b.) has a +DC and GND for a power supply of 12 to 24

VDC. Up to three communication ports (either RS-232 or RS-485) are available to connect the

SmartSensor to a modem or other communication device. Typically one RS-485 port is available

plus one or two RS-232 ports. Figure 5 shows 2 communication ports. Refer to the appendix for

pin assignments.
