3.Auxiliary

The sampler comes standard with two interface receptacles.

•12 V dc (Power Input)

•Auxiliary (Multi-purpose input/output port)

•RS232 (Serial communications port)

•Thermal (Control port for heating and cooling system)

In addition, the sampler can be used with a wide variety of optional devices:

• Level and Flow Monitoring		Three additional analog inputs of
	(Sensors)	4–20 mA or -4.0 V dc to +4.0 V dc
•	pH/ORP	• 4–20 mA Current Loop Output
•	Conductivity	•	Modem
•	Dissolved Oxygen	•	Rain Gauge

•Temperature

1.3.1 Receptacle Caps

Interface receptacles are covered with push-on receptacle caps. These caps protect the connector pins from dirt and moisture and should be attached to any receptacle not in use.
