Observator introduces Iridium support for OMC-048 data logger

In July 2020, Observator introduced the OMC-048 data logger as a successor to the now retired OMC-045 datalogger. After the initial introduction of the OMC-048, development has continued. New drivers have been added and other improvements have been made. The latest addition is the support for satellite communication via the Iridium network. You can now use our Iridium Edge Modem (OMC-IEM) connect to the data logger via an RS232 cable. The logger then sends the collected sensor data in SBD (Short Burst Data) messages to the Iridium network. The Iridium network places the data in an e-mail and forwards it to the e-mail address you specified. The data format is compatible with our OMC-Data-Online server software, which can read the e-mail message and process and display the data.

The logger now supports the Xylem/YSI EXO series of multiparameter probes, our own NEP-5000 family of turbidity sensors, NMEA-PTID data format for tide gauges, analog inputs, NMEA for GPS and more. Also included is the ability to synchronize the internal clock with GPS or NTP time servers.
