1 Introduction
This versatile data logger is the successor of the successful OMC-045-3 data logger. It has a large
number of inputs and outputs, including SDI-12, ModBus and analog. The OMC-048 uses the latest
technology and includes a powerful processor as well as a state-of-the-
art LTE ‘world wide’ modem for
connecting to the cellular network.
Thanks to the advanced processor and the availability of a large collection of input and output drivers, it is
possible to write your own programs (Python scripts) for maximum flexibility. For common applications,
scripts will be available for you to download, so most users will be able to use the logger without any
programming.
