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
w
arnings) 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).

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.
