1 Introduction
This document is applicable to the FM 36xxi, FM 37xxi and FM 38xxi series
of on-board computers. These products are collectively referred to as FM
3617i/FM 3717i/FM 3817i.
The FM unit is a comprehensive fleet management solution, comprising
of an in-vehicle on-board computer as well as an easy to use web
interface, MiX Fleet Manager, which enables access to fleet management
information anytime, anywhere.
The FM3717i/38171 range supports 3G and 3.5G HSPA+, 3-Axis
Accelerometer (up to 16 G) and GLONASS.
The FM3617i range supports 3-Axis Accelerometer (up to 16 G) and
GLONASS.
Please note: This document will use the word “vehicle”, referring to vehicles and all other types of electrical
equipment where these units may be installed.
1.1 Analogue/Digital Inputs
The FM 3617i/FM 3717i/FM 3817i is equipped with eight analogue/digital inputs (I1-I8), which can be used to
monitor either digital or analogue signals. The eighth Analogue/Digital input (I8) is shared with the fourth
frequency input (F4). Input signal voltage range and resolution is selectable from the MiX Fleet Manager
software. For digital type input signals, switching thresholds can be defined in the software, which, when
crossed, trigger an event that records the specified data. Other actions (including the switching of relays and
warnings) can also be defined. Please refer to the “Specifications” section, of this document, for more details.
1.2 Frequency Inputs
The FM 3617i/FM 3717i/FM 3817i has three frequency inputs, which can be used to record frequency type
signals. The fourth frequency input (F4) is shared with the eighth Analogue/Digital input (I8). Provision is made
for a wide range of signal types on F1 and F2. F4 will only read TTL signals, or signals that span at least 0V
to 5V, e.g. -5V to +24V. F3 is no longer a frequency input, but it is connected to the internal GPS and acts as
a GPS output (9600 baud).
2 System Requirements
The FM 3617i/FM 3717i/FM 3817i is designed for use in vehicles. Special vehicles and working machines with
a 24 to 110 volt DC battery system will require a voltage converter to facilitate the required 12V to 24V power
supply input. MiX Fleet Manager is required to complete the installation process.

Note that the product is rated IP 54, on condition that the connectors are facing downwards when installed.
Thus, if there is a possibility of water ingress, care should be taken to mount the product with the connector
facing downwards.
3.1.7 Installation of Wiring
The FM 3617i/FM 3717i/FM 3817i is compatible with all FM300 harnesses.
Note the product’s wire gauge cross-sectional area. If the wire gauge cross-section is reduced, current density
increases which may cause the wiring to overheat.
Cables should be routed in existing channels and should not be routed parallel to ignition cables or
other cables subject to high current (including cigarette lighter socket wires).
Cables should be fixed with cable-ties or adhesive tape.
Do not route cables over moving parts.
Do not fix cables on the steering column.
Ensure that the cables are not exposed to pulling, pressure or shearing deformation.
If the cables are routed through drilled holes, rubber grommets or similar protection should be used.
Suitable cable-strippers should be used to strip insulating material from cables and cable-strippers
should be adjusted to avoid damaging or separating the wire strands.

6 | P a g e
Cables should only be connected using a soldering iron or suitable crimping lugs.
A proper crimping tool should be used on all crimping lugs.
Careful attention must be paid to the manufacturers’ safety regulations for all tools used.
Insulate all exposed wires to prevent short-circuits. Use good quality adhesive tape or heat shrink
(provided).
Connections to vehicle power supply must be installed with a fuse.
Be aware that short-circuiting may be caused by faulty connections and crushed or damaged cables.
Short-circuiting the vehicle’s electrical system may result in fire, explosion of the battery and/or
damage to other electrical systems. To prevent this, all connections carrying current must be soldered
and insulated correctly. Other connections such as the speed signal, RPM signal, brake light or clutch
switch can be made with crimping lugs.
Incorrect connections can lead to short circuits. Connections should only be made in accordance with
the vehicle’s wiring diagram.
Current and voltage should be measured with a multi-meter or diode test lamp.
The use of inadequate test equipment may result in damage to control devices or other electrical
systems.
Route the harness in such a way to prevent water condensation formed on the cable to run into the
unit. This can be achieved by having the harness at a lower point just before it connects to the unit.
Shortening of antenna wires:
It would be better to circle/coil excess wires. Avoid sharp bends at the zigzags. Take
care not to tie coax wires too tight. The coax should not be squeezed or pinched.
Using the broadest possible cable tie.
The best place to circle/coil the wires is about 300 mm in line from the antenna.
If the GSM and GPS antennas are both coiled, they should be spaced apart.
Do not mount the GSM antenna against a metal surface. This affects GSM reception
and transmission.

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 3rd 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.

10 | P a g e
4.5 Connection
The CAN wires are designated by a yellow and a green wire, connected to pins 7 and 14 on the Main Harness.
If they are not already twisted, they should be twisted together.
Colour coding of the wires are shown in the tables below:

4.5.1 Wire lengths
The CAN wires between the FM 3617i/FM 3717i/FM 3817i and the vehicle’s bus should be no longer than 300
mm. Excessive wire length may cause interference with the vehicle’s normal operation.
4.5.2 CAN jumper settings
Warning: It is very important to ensure that these jumper settings are correct at installation time. If these
jumpers are set incorrectly it is possible that when a new configuration or script is downloaded to the FM
3617i/FM 3717i/FM 3817i, it could bring down the CAN bus of the vehicle and interfere with the operation of
the vehicle. Conduct ESD precautions as described in section 3.1.4

4.5.3 General Rules for CAN Jumpers
If connectivity is to the vehicle CAN FMS “firewall” then both jumpers are normally in as shown in
Figure 3. Some FMS gateways requires an “acknowledgement” message on the hardware layer in
order to send any messages and therefore the FM must be in the “read/write” mode. Check that the
resistance is 60 Ohms after connecting the FM unit and then remove the “Termination Jumper” if
necessary as shown in Figure 4. Sometimes a terminating resistor or other telematics equipment may
already have a terminating 120 Ohm resistor fitted; in this case the terminating resistor can be
removed and the “read/write” resistor can be left in as shown in Figure 4
.
If there is no FMS “firewall” fitted, then connectivity will be to the vehicle CAN “hot side” – only with
customer’s permission –then both jumpers must be removed as shown in Figure 1. Prior to
commencing the installation, check that the vehicle CAN resistance is 60 Ohms, if it is not, e.g. 40
Ohms or 120 Ohms, inform the customer as this should be corrected prior to commencing the
installation. If a reading of 40 Ohms is present, prior to connecting the FM unit, this could indicate that
another telematics system may already be present with a terminating 120 Ohm resistor fitted and this
will distort the CAN resistance reading and may cause CAN errors to be seen.
4.6 Inserting of SIM card
In order to insert the SIM card, the following steps must be followed:
Observe ESD precautions as prescribed in section 3.1.4
Remove the front panel
The SIM card holder is located under the pc board
If required the pc board can be slid out of the housing to access the SIM card holder
Insert the SIM card as indicated below
4.7 Beep and flash codes
