==CAN \ Tachograph==
'''CAN \ Tachograph''' are used to configure device when connection of CAN1 and CAN2 BUS lines are performed. <br>
Teltonika recommendations: <br>
* FMM650 CAN1 connected to vehicle's FMS(J1939) BUS line<br>
* FMM650 CAN2 connected to vehicle's Tachograph - Instructions can be found on [[FMB640_and_Tachograph_Solution|FMB640 and Tachograph Solution]] wiki page;
==Tachograph Settings==
<br />
'''In FMM650 configurator “CAN/Tachograph” section tachograph settings should be set in order to download files.<br />'''
<br />
DDD download source – to which CAN line tachograph is connected;<br />
<br />
Tachograph ignition source – which DIN is connected to vehicle ignition ("Ignition" parameter - tachograph ignition source will be the same as configured in "System" -> "Ignition Source");<br />
<br />

FMM650 can be wired to Tachograph using instructions provided in [[FMB640_and_Tachograph_Solution|FMB640 and Tachograph Solution]] wiki page.
==WEB Tacho Settings==
'''WEB Tacho Settings''' are used to configure Tacho WEB server to which device periodically connects.
WEB Tacho Settings:<br />
'''Status''' - functionality enabling;<br />
'''Domain''' – server domain where files will be send;<br />
'''Port''' – server port where files will be send;<br />
'''Start delay''' – delay after turning on ignition to start procedure of file sending.<br />

==FMS settings==
FMS settings is used to configure FMS source. <br><br>
If you have FMS wired to FMM650 CAN1, FMS source should be selected as CAN1.<br>
If you have FMS wired to FMM650 CAN2, FMS source should be selected as CAN2.

==CAN Termination resistor==
FMM650 has electronically controllable CAN termination resistor on CAN1 and CAN2 lines.
This means that CAN line 120Ω resistance can be switched ON or OFF.
[[image:CAN Terminator.png]]
In most cases - devices in CAN communication lines have 120Ω between CAN LOW and CAN HIGH lines. When connecting two CAN devices in parallel - overall resistance becomes 60Ω which is suitable for correct CAN communication.
<br>By default FMM650CAN Termination resistor is enabled - therefore when connecting to only one external CAN device - overall resistance will be 60Ω.
<br>If FMM650 has to be connected to CAN line where there already are 2 main devices with 120Ω resistance - <b>CAN termination resistor has to be turned off </b>. Then overall resistance of CAN line is left unchanged at 60Ω - therefore CAN communication is uninterrupted.
