Before connecting tachograph wires, it is required to measure CAN line resistance
Before connecting tachograph wires, it is required to measure CAN line resistance
while tachograph is switched off:<br />
while tachograph is switched off:<br />
#Turn off the vehicle ignition;<br />
#Measure resistance between the C5 (CAN2 H) and C7 (CAN2 L) contacts;<br />
#If the multimeter shows ~120 Ohms, skip the next step;<br />
#If the multimeter shows kilo Ohms resistance then it is needed to connect tachograph C8 (CAN-RES) and C7 (CAN2 L) contacts with wire and then perform further actions;<br />
#Re-measure the resistance of the line – it has to be ~120 Ohms.<br />
#Connect CAN2 L and CAN2 H wires to tachograph (C5 (CAN2 H) and C7 (CAN2 L))<br />
* All of the same level CAN-L and CAN-H wires must be interlaced with each other.<br />

used for getting status information. SMS response is of such structure:
used for getting status information. SMS response is of such structure:
[T] – Tachograph presence on bus:<br />
[T] – Tachograph presence on bus:<br />
* 0 – Tachograph doesn’t respond on bus;<br />
* 1 – Tachograph responds on bus.
*0 – Tachograph doesn’t respond on bus;<br />
*1 – Tachograph responds on bus.
[R] – Response to Open Remote Session validity check:<br />
[R] – Response to Open Remote Session validity check:<br />
* 0 – Wrong or unknown response (failed to open Remote Session);<br />
* 1 – Tachograph responds positively (Remote Session opened successfully).
*0 – Wrong or unknown response (failed to open Remote Session);<br />
*1 – Tachograph responds positively (Remote Session opened successfully).
[C] – Response to Close Last Authentication Session validity check:<br />
[C] – Response to Close Last Authentication Session validity check:<br />
* 0 – Wrong or unknown response (failed to close last authentication session);<br />
* 1 – Last authentication session closed successfully, device is ready to open new authentication session.
*0 – Wrong or unknown response (failed to close last authentication session);<br />
*1 – Last authentication session closed successfully, device is ready to open new authentication session.
[K] – K-Line data presence on bus:<br />
[K] – K-Line data presence on bus:<br />
* 0 – K-Line data not present on bus;<br />
* 1 – K-Line data present on bus.
*0 – K-Line data not present on bus;<br />
*1 – K-Line data present on bus.
[ABCD] – FMS data presence on bus:<br />
[ABCD] – FMS data presence on bus:<br />
* 0000 – FMS data not present on bus;<br />
* Non-zero – FMS data detected on bus.
*0000 – FMS data not present on bus;<br />
*Non-zero – FMS data detected on bus.
'''SMS answer which shows correct line connections looks like “CAN_2:[111],[ABCD], K-Line:[K]”.'''
