4.3 Overview
Installation of FM 3617i/FM 3717i/FM 3817i should only be carried out by trained installers.
Improper connection of the FM 3617i/FM 3717i/FM 3817i to the
vehicle’s CAN or J1708 bus may
cause interference with the vehicle’s normal operation.
The FM 3617i/FM 3717i/FM 3817i is already loaded with compatible device drivers.
The unit still needs to be configured for the vehicle in which it will be installed, and the vehicle ID
and odometer still need to be configured. Specifically the FM 3617i/FM 3717i/FM 3817i may not
record any CAN or J1708 data until it is configured.
It is important to select the correct mounting location for the FM 3617i/FM 3717i/FM 3817i. Do not
mount close to air ducts that can channel cold or hot air directly onto the unit.
Do not twist the FM 3617i/FM 3717i/FM 3817i unit if mounted on an uneven surface.
The GSM antenna is to be mounted more than 20cm away from the human body under normal
operating conditions.
After installation, verify that no interference is caused to the vehicle’s electrical system. Check dashboard
warning lights and error messages. Should any error conditions exist, remove the FM installation and contact
MiX Telematics for assistance.
4.4 Tools and inspection
Supporting tools
Multi-meter
Oscilloscope
Laptop with CAN to USB interface (for example Vector CANcaseXL)
Identify possible CAN busses by looking for twisted pair wires in the vehicle.
With the vehicle’s ignition turned on, measure the voltages relative to ground on each of the wires using a
multi-meter.
For CAN, the voltage readings of the two wires should be very similar (usually 2.5V), with CAN-H likely to
read only slightly higher than CAN-L.
Using an oscilloscope, the actual data signal can be probed.
With a properly configured 3
rd
party CAN tool, like the Vector CANcaseXL, the actual data can be recorded.
CAN Baud rates of 250kb/s (SAE J1939) and 500kb/s are the most common.
