TYPE ML-2012/13 1 Product Description The ML-2012/13 is designed to retrieve, and store data from various sensors. This data is logged onto the embedded SD-card. Also the stored data can be send from the data logger to any remote computer you like.
To connect the logger to an AC integrated in cover. power grid. ML-2012/13- As ML-2012/13, but without enclosure and PCB only antenna. The data logger will be supplied without pre-mounted cable glands, giving the user the freedom to choose the number and size of the glands them self. Although glass fiber reinforced polyamide is a tough material, drilling gland holes is easy.

USER MANUAL TYPE ML-2012/13 1.1.2 ML-2013 The waterproof IP67 enclosure of the ML-2013 exists out of a casing and cover of glass fiber reinforced polyamide (PA66/GF20) with in between a silicon gasket. The ML-2013 can be used outdoors. 1) Analog inputs...
The wireless data functions will only work when an activated SIM, with a valid subscription is placed in the ML-2012/13. In the menu the configuration and network settings must also mach to those supplied by the SIM card provider. The pin code of the SIM card must be removed prior to insertion in the data logger. To prevent problems with the SIM card it can be inserted in a mobile phone or GSM data modem.
Next, connect your sensors, please consult your sensor’s manual for wiring. 2.4 Connect to a PC OS compatibility: The ML-2012/13 can be connected to any PC with USB 2.0 running on Microsoft Windows XP, Windows Vista or Windows 7 Installation procedure for the internal USB adapter for Windows XP is given on the CD.
USER MANUAL TYPE ML-2012/13 3 Operating Basics 3.1 Configuration menu The ML-2012/13 can be configured by means of terminal emulation software like ‘hyper terminal’. Our own terminal emulation software ‘YDOC-terminal’ can be downloaded from www.your-data-our- care.com The menu is comprehensive and easy to use. For each different sensor the same approach is used.

USER MANUAL TYPE ML-2012/13 Next thing is the setup of the data outputs. Before that, we have to configure the general modem settings for GPRS operation. Consult your GPRS- provider for the correct local settings. In the reference, a table is included with some international GPRS- providers and their settings.

4 Reference 4.1 Principle of Operation Your ML-2012/13 Data logger is capable of collecting and storing data of multiple sensors. To accomplish this, many tasks are performed. These “tasks” are scheduled and executed on their specified time. The timing of this process is very important and is determined by the internal scheduler. This scheduler keeps track of all the internal states of the various tasks and assigns processor time to the different tasks.
4.2 SDI-12 The ML-2012/13 is provided with an SDI-12 port. This port is connected to port 2 and is shared with the normal RS232 operation. This means that the user has to select whether he wants to use RS232 or SDI- 12.
4.3 RS232 Your ML-2012/13 comes with 2 RS232 ports, capable of baud rates of up to 115200 bps (230400 bps on request). The ports are: port 1 and port 2. Port one is shared with the RS-485 port and port 2 is shared with the SDI-12 port.

Only one slave can respond to the requests of the master at a time. To set up your RS485 sensor for use with the ML-2012/13, make sure that the address is programmed correctly, and that the sensor address is unique.
Some devices don’t need a power supply, but take their power from the current loop. But the primary circuit of the ML-2012/13 does NOT provide power for this. In this case, you need the power switch to provide the energy for the current-loop. Consult the manual of the loop-powered device you like to connect, and use the positive side of the power switch for the power supply.
USER MANUAL TYPE ML-2012/13 4.6.4 Bridge of Wheatstone The bridge of Wheatstone (the principle of operation of a load cell) is a circuit, consisting of 4 resistors. Below a circuit is given: Given, all R’s are the same the output voltage will be 0 Volts. In practice, one of the resistors is replaced by a variable resistor (often a strain gauge) .
USER MANUAL TYPE ML-2012/13 4.6.6 Analog Differential input 5 Analog input 5 is a Differential input with a build-in user selectable input-amplifier. Therefore channel 5 has a user selectable range. The user can set the range of the input according to his preferences. This is done by adjusting the so called “port mode”...
Attention: The coil input of the ML2012/13 is so sensitive that a short piece of unconnected wire is enough to let the ML-2012/13 “pick up” signals from the environment. Be aware of this, and use a shielded cable. The reception of RF-signals can lead to problems with the performance of the system.
In some circumstances, normal data-logging is not sufficient for managing your process. For keeping track of certain, often critical, conditions, the ML-2012/13 is equipped with direct alarming options. Alarming-limits and hysteresis are used to manage these special events. The table below shows the different types of alarming-limits.
In time however, the need for additional features may arise. For example, a new serial sensor is introduced on the market and a customer wants to connect this sensor to the ML-2012/13. When YDOC has extended the firmware to support that sensor, a new version of the firmware is released. After the user has performed the firmware upgrade, his “old”...
Each driver can handle (collect or send) a number of parameters. The total number of parameters is limited to 64. So, theoretically, the ML-2012/13 can handle up to 16 sensors with each 4 parameters. But in this case there is no output possible. In most cases two or three drivers are needed for minimum operation (internal driver, tcp output-driver, or email-driver).
4.11 SD-card The SD-card used with the ML-2012/13 is a SANDISK 2GB type Card. It is formatted in FAT 32, and is compatible for use with a PC. Don’t use other cards than this type, because the performance of the data logger may be harmed.
USER MANUAL TYPE ML-2012/13 Parameter Code: The abbreviation of the full parameter name, it may be up to 7 characters long. Parameter Name: The name of the logged parameter, it may be up to 31 characters long. Parameter Unit: The unit representing the physical dimensions of the measurement, it may be up to 15 characters long.
USER MANUAL TYPE ML-2012/13 4.12.2 System-records The System-records are used to log system related information. System-records do not contain normal measurements. A system-record is made, when an awkward situation is encountered, for instance, when a sensor is not replying to a request from the logger. System-records are used for monitoring system- performance.
A warm up time of 5 minutes is possible and can be used in rare situations, but the battery-life will be shortened enormously. In such rare cases, consult your local YDOC-supplier for a calculation of battery-life, before exploiting your data logger.
USER MANUAL TYPE ML-2012/13 4.14.2 Digital Pulse Sensor Digital Pulse sensors like for instance rain gauges are based upon the “reed contact” principle. The rain gauge has an internal bucket with a very precise volume. It is constructed to tip over when it reaches a specified amount of water.
USER MANUAL TYPE ML-2012/13 i.e. when your rain-gauge has a tipping bucket with a size of 0.2 mm rain, it will take five buckets for 1 mm rain. So, in this case the value 5 has to be entered for the “pulses per unit”.
TYPE ML-2012/13 4.15 Power supply The ML-2012/13 PCB is designed to work with a power supply of minimum 0.8 to maximum 5V DC The ML-2012 can be powered with a D-size 3.7V Lithium cell or external supply of max 5V DC.

The battery of the ML-2012/13 Data logger is designed to last for the lifetime of the instrument. It should not be necessary to replace this battery. If it has to b replaced anyhow, it has to be done by an YDOC- certified dealer.
4AT fuse type TR5. 7.2 ESD The ML-2012/13 data logger is equipped with an ESD (Electronic Static Discharge) protection on all “outside world” leads. i.e. comports and analog inputs etc. Though it is designed to withstand a certain amount of electrical discharge (human body model) it is strongly advised to take precautions while operating or servicing the data logger.
Temp 10 .. 30 °C If the ML-2012/13 is delivered in its standard protecting enclosure, it is strongly recommended to use this case for all transportation, until the final location of operation. This enclosure is especially designed to protect the data logger from being damaged.

13 Trouble shooting If you encounter problems with the data logger, you can start checking the following. First try to set up a connection, via USB, and use the program, YDOC-terminal, to communicate with it. If that doesn’t work, you have to check the battery-power, so you have to open the case. Do this in a dry and clean environment, NOT in the field.
