Connect the communications module
Items to collect:
• Data acquisition system or controller
• Communications module (configured)
• External power source, 6-24 VDC (12 VDC nominal)
1. In the field, connect the communications module to the data acquisition system or controller.
Refer to the documentation supplied with the communications module for wiring information.
Refer to Data transmission and power wiring
transmission.
2. If the data acquisition system or controller cannot supply power to the communications module,
connect an external power source to the communications module. Refer to
power wiring on page 17 for the wiring requirements for external power.
Data transmission and power wiring
To connect data transmission lines to the communications module, make sure that the transmission
cable is sufficient for the operating current and will transfer the data without distortion. For up to
305 m (1000 ft) of cable, three 26 AWG wires are sufficient.
To connect external power to the communications module, make sure to use two 18 AWG wires for
power. Smaller power wires can be used if the power supply is near the instrument.
Instrument deployment
Items to collect:
• Deployment cable
• Sensor guard
1. Connect the deployment cable to the communications module. Make sure to use the deployment
cable and not the calibration cable.
2. Connect the deployment cable to the instrument.
3. Remove the storage/calibration cup and install the sensor guard. Keep the storage/calibration cup
for later use. Refer to
