WARNING
THE FOLLOWING OPERATING INSTRUCTIONS ARE FOR USE BY QUALIFIED
PERSONNEL ONLY. TO AVOID DAMAGE OR MALFUNCTION, DO NOT PERFORM
ANY OPERATING OTHER THAN THAT CONTAINED IN THIS MANUAL. ANY
OPERATOR SHOULD BE SKILLED WITH A TECHNCAL BACKGROUND BEFORE
OPERATING THE DEVICE.
PREFACE
Congratulations!
With your purchase of an YDOC Low Power data logger with mobile network capabilities.
This manual describes the operation and (hardware) installation of the ML-2013/ML-x15/WDL-x14 data
logger.
The chapter Getting Started briefly describes the data logger, prepares you to install it, and tells you how
to put it into operation.
The Chapter Operating Basics covers basic principles of operation of the data logger. The operating
interface (menu) and the tutorial examples, rapidly help you to understand how your data logger operates.
The Chapter Reference teaches you how to perform specific tasks and provides a complete list of
operating tasks and useful background information.
The Appendices provide a list with all available options, and other useful information.
We recommend reading this manual carefully before installation of the data logger.
Warranty
All YDOC instruments are warranted for 3 years against defective materials and workmanship. Any
questions with respect to the warranty mentioned above should be taken up with your YDOC Distributor.

DATA LOGGER MANUAL
Manufacturers of low power instruments page 10
Product Description
The data logger is designed to retrieve, and store data from various sensors. This data is logged onto the
embedded / removable SD-card. Also the stored data can be send from the data logger to any remote
computer you like. To use this feature, you need a valid SIM-card. Contact your local telecommunications
provider for more information on the SIM card you will need. The unit accepts various power sources,
selectable by the different version types. The user should connect his sensor(s) of preference to the
connector board of the device. Captured data can be stored, send, visualized and manipulated in many
ways.
The data logger is a small, ultra-low power, high-end data logger with built-in 2G/3G cellular-modem. This
small data logger, is further provided with an internal temperature sensor, 2 or 4 GB micro SD-card and
an SIM card slot. The logger can be powered by an internal 3.6 Volt Lithium battery that will last for years
when the logger is configured in a low-power mode.
Depending on model and edition a data logger can acquire physical signals by current loop inputs, voltage
inputs, resistance inputs and digital inputs. They can also be provided with RS232/RS485/SDI-12 port to
capture serial data (ASCII, MODBUS-RTU/ASCII, NMEA-0183, SDI-12) or to connect an accessory
(Camera, Display, GPS, Satellite modem).
External sensors can be powered by the data logger itself, to prevent them to consume power while the
data logger is a sleep. The excitation voltage is switched off during sleep as well.
Key features:
- A maximum sample rate of 4 Hz,
- Recording buffer up to 4 GB,
- Analog inputs (Except DS editions),
- Serial port(s) (Except AD editions),
- Digital input(s)
- Digital output
- Internal micro SD-card with standard FAT-32 File system for easy use with a PC,
- Easy configuration by menu items of embedded terminal application,
- Can be used with Windows XP, W7, W8 and W10
- Low power / long Battery life (see specification sheet),
- Embedded 2G/3G modem for remote operation,
- Alarming by SMS, e-Mail or MQTT
- Log data transfer by HTTP(S), e-Mail, FTP(S), secure TCP or MQTT
- Camera picture transfer by HTTP(S), e-Mail, FTP(S), secure TCP or MQTT
- Remote FW-upgrade & Configuration update by HTTP(S), secure TCP or MQTT
- Internal voltage convertor for supplying 12 VDC power to the connected sensor(s),
- Stable excitation voltage to power Wheatstone bridged sensors (ML-2013 only),
- Firmware upgrade over the air for adding new features to your device.
- Remote configuration over the air, for adjusting your configuration from remote.
