Hi,
Measuring voltage with a mutltimeter
* CAN HIGH VOLTAGE- value should normally be in between 2.5 and 3.5 Volts. Measured on a machine that is running, it will usually range between 2.7 and 3.3 Volts
* CAN LOW VOLTAGE- value should normally be in between 1.5 and 2.5 Volts. Measured on a machine that is running, it will usually range between 1.7 and 2.3 Volts
If you find the right wire for CAN High and CAN Low you can scan the program number number using the autoscan feature, list of compatible program number will come on the list kindly check this link Scan1.jpg (1366×728) (teltonika-gps.com)
Please note that auto-scan feature is currently supported just with FMB140 device, which has built-in CAN adapter.
If you didn't find the correct wires please kindly contact with our Sales managers, please contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to [email protected]
