The 3004MI/3006MI NRL is an Iridium SBD datalogger that takes advantage of the Iridium satellite network short burst data subsystem. It is a high reliability message based system, providing reasonable cost satellite communications and a low latency. This service is ideal if you have a requirement for short messages to report sensor data. Latency from such systems is in the order of minutes and the satellite airtime costs reflect this low latency service. The 3004I/3006I 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.
