Preface
This manual is intended for the user of the OMC-048 Scriptable Data logger.
You will find all information related to the hardware v1.03 (released in June 2022).
Detailed and up to date information concerning drivers and firmware is available in the OMC-048
Configuration Manual, which is available for download on the Observator.com website.
It does not include explanation of the Python scripting language. It assumes Observator Instruments or a
third party supplies the Python application for your logger.
If you are interested in scripting the logger yourself, we kindly refer to the OMC-048 Webmanual, which is
available on our Observator.com website.

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.
1.1 Hardware revision 1.03
This manual assumes you have the updated hardware 1.03.
Main differences with previous version:
1. 1 switchable 12VDC power output has been converted to 5VDC (Available outputs are now: 3 x 12VDC
and 1 x 5VDC).
2. The reset button is updated to a software controlled reset, button on previous version resulted in a hard
reset.
3. Internal ADC for (logger) power supply voltage monitoring.
4. Vref output changed from 2.5V to 5V.
2 First use
