Overview

The 3004MH/3006MH Neon Remote Logger is a Microsatellite datalogger that makes use of a microsatellite network as the method of sending sensor data from the field to the Neon Server. The microsatellite network is a message based system, providing low cost satellite communications over a high latency service. This low cost service is ideal if you have a requirement for occasional short messages to report sensor data, when the latency of the messages is not very important. Latency from such systems is in the order of hours and the very low satellite airtime costs reflect this high latency service.

The 3004MH/3006MH is housed in a polycarbonate case which has a smaller form factor than the standard metal enclosure 3004. It connects to sensors in the field, collects readings from those sensors, logs the sensor data and provides control functions.Using Starlog V4 PC software loggers are programmed with a scheme to specify which sensors to log and how often to store readings. It also provides information about memory and battery duration for that scheme.

Control outputs are also set up in the scheme by setting up custom events. A wide range of sensor types are supported including analog sensors, frequency counters, digital inputs as well as Modbus and SDI-12 instruments. Control of external equipment (such as triggering a relay when a user defined event occurs, or initiating a shutdown), can be accomplished via Open Drain FET output. Sensors are connected to the logger via pluggable terminal blocks, allowing for easy removal of the logger if servicing is required.
