USER MANUAL
TYPE ML-2012/13
Manufacturers of low power instruments
page 27
The modem inside the ML 2011 is equipped with the latest firmware-version available. There is no need
for upgrading the software, even in the near future we don’t expect this to be needed. But just in the
unlikely event of the need of a modem firmware, it is possible to do so. This can be done with the modem
mounted on the board (in circuit programming). The procedure of upgrading modem firmware is not
covered in this manual. For more information, consult your local YDOC dealer.
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. (This is because of the speed of the SD-card, and even the low power
performance can be affected by using a slower card). The contents of the card may be read on a PC by
using a card adaptor, or can be downloaded from the card, by using the menu-option “Data-download”.
We recommend not removing the SD-card from the logger.
4.11.1 Inserting an SD-card
At the factory, the SD-card is already installed, but when the cards need to be re-inserted, pay attention to
the orientation of it. It should be inserted with the (gold-plated) terminals up.
4.12 Data Format
The ML-2012/13 data format uses different records for data output. There are two types of data records:
- D-records
- S-records
Header:
In every log file, first a header is transmitted. This header contains all information about the data following
in the next records. The syntax of the header is;
<’L’> <’;’> [ <Parameter Code> <’;’> < Parameter Name > <’;’> < Parameter Unit> <’;’>]
This means that the line starts with an ‘L’ character, followed by a semicolon. Then the code, name and
unit of the parameter follow. These last 3 elements must be repeated for each logged parameter.
Example header:
So the header consists of these elements:
1. L
2. Parameter Code
3. Parameter Name
4. Parameter Unit
5. ;
L;RCi;Rest Capacity;%;PTi;Processor
Temperature;C;Vi;Voltage;V;AVGCi;Average Current;mA;OCi;Operating
Cycle;sec;S%;GSM Signal;%;MAXCi;Max Current;mA
