==CHECKING CONNECTION (TACHOCHECK SMS)==
<br />
After successful connection “tachocheck” sms message can be sent to device for checking if
data presented on connected lines, by another words if connections were done correctly. It is
used for getting status information. SMS response is of such structure:
CAN_2:[TRC],[ABCD], K-Line:[K]<br />
[T] – Tachograph presence on bus:<br />
• 0 – Tachograph doesn’t respond on bus;<br /> • 1 – Tachograph responds on bus.<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).<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.<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. 7 [ABCD] – FMS data presence on bus:<br />
• 0000 – FMS data not present on bus<br />
• Non-zero – FMS data detected on bus.<br />
'''SMS answer which shows correct line connections looks like “CAN_2:[111],[ABCD], K-Line:[K]”.
'''Such SMS answer means DDD files can be downloaded from tachograph.'''
