===Tachograph Counter related elements===
+
Newly added IO elements (AVL ID 10504-10517 from 01.02.12 firmware version) include data reading from Tachograph Counter functionality – displaying daily/weekly remaining driving and rest times on tachograph menu.<br>
+
Note that these parameters can be optional on your tachograph - meaning that by default not all the tachographs have this feature enabled/supported from the factory.<br>
+
For example – VDO DTCO tachographs support the Counter functionality from version 2.0, however in OEM tachograph versions – non universal tachograph – meant specifically for truck manufacturer i.e. Mercedes/DAF – Counter functionality can be disabled from the factory.<br>
+
'''In order to properly read these IO elements with FMX640 – Counter functionality has to be enabled.'''<br>
+
VDO DTCO 2.1 tachograph can be updated via “DTCO VDO Counter Update Card” – '''P/N A2C5951660366'''<br>
+

Newer DTCO versions can have the Counter functionality enabled by entering the license key provided by the manufacturer.<br>
+
To see if new IO elements will be read from your tachograph, we recommend contacting your local workshop, specifying the tachograph part number and following the workshop instructions if any are required.<br>
