1 Introduction
Thank you for purchasing an Inventure product. Your new Inventure CL-J1708 device is a
carefully engineered, high quality durable product with modern features. It is designed to give
you the quality and convenience you expect from an automotive measuring instrument.
To familiarize yourself with all the features of your unit, please read the following instructions
carefully. Retain this guide for future reference.
2 Function, application fields
Most modern (personal and commercial) vehicles are equipped with communication system,
such as J1708 system. The Inventure CL-J1708 device is designed for capturing vehicle data
from such communication system.
The Inventure CL-J1708 device is a contactless J1708 bus reader applying non-intrusive
technology to acquire vehicle specific data. The usage of the device eliminates any vehicle
warranty issue since avoids galvanic connection to vehicle communication wires.
Inventure CL-J1708 device can be useful for any aftermarket device that requires vehicle
J1708 data such as:
•Automatic Vehicle Locating system
•Fleet Management System
•Vehicle status display
•Fuel control
•Etc.

3 Notices
•Before starting the installation please read this document carefully! Appropriate
operation of the device depends on proper installation.
•Do not remove the silicone rubbers from the cover of the contactless unit during the
installation!
•Usage of the device is permitted for industrial purposes only. It must not be used in
situations in which human lives depend upon the operation of this equipment.
•The installation of the device may eventually be in conflict with a country’s regulations
or the vehicle manufacturers (OEM) instructions. The conformance shall solely be the
Customer’s responsibility. Improper device installation may have an effect on vehicle
warranty.
•Inventure takes no responsibility for any damages originated in device installation.
•Aftermarket installed devices connected to J1708 bus may affect negatively the
operation of CL-J1708.
•Exceeding maximum allowable power supply may impair the device.
•Vehicle ignition must be off at the start of installation.
•Misuse and/or physical damage on device may lead to loss of warranty.
•Vehicle J1708 wires must not be cut, pierced, or soldered. J1708 wires must be intact
for undisturbed vehicle J1708 communication. Inadequate connection to vehicle J1708
wires may affect vehicle operation and may cause safety issues.
•Fix Inventure CL-J1708 device properly to avoid hitting to vehicle elements, or rattling!
•Device should be installed away from direct heat and moisture. Installation in cabin is
recommended.
•Avoid installation at steering column and above pedals!
•Although device contains (Multi)fuse, application of a 1…3 Amp fuse at power source
is highly recommended.
•Inventure CL-J1708 device must be installed by professional skilled in automotive
electronics.
•Avoid damaging, polluting or scratching sensor surfaces! Also ensure clean wire
surfaces (use isopropyl-alcohol for cleaning if necessary)!
•The AVL system input must not transmit any J1708 message, only receiving devices
are allowed to connect to CL-J1708 output, (e.g. FMS Gateway).

4 Installation
4.1 Connection ports of the Inventure CL-J1708 device
•Signal input. Contactless J1708 sensor surfaces (horizontal, High and Low stripes)
•Power supply. Black: GND, Red: power (constant power or ignition)
•J1708 output. Brown: J1708B, Amber (Orange): J1708A
Figure 2. Internal view of CL-J1708
4.2 Installation steps
1. Mount output connector to Inventure CL-J1708 device matching to the AVL input!
2. Check voltage level of vehicle J1708 A and B wires! (A is more positive than B.)
3. Make sure ignition is off
4. Provide power supply connection (7…32 V). Recommended to use free points of fuse
box. (If not available tap a low amperage, not safety-critical battery or ignition wire with
3M UB2A - or similar - IDC tap splicing connector!)
5. Inventure CL-J1708 output installation.
a. For Inventure FMS Gateway device: connect the 2x4pin Minifit connector
b. For other telematic device: use the appropriate connector
6. Turn on ignition (optional)
7. Place cover of CL-J1708 device under vehicle J1708 wires! Ensure vehicle J1708 wires
not to be strained and/or bended sharply, but run straight in the indicated High and Low
slots! Please do not remove the silicone rubbers from the cover!

8. Place the cover to match the CL-J1708 device. The hole on the cover must be aligned
with the status LED.
9. (Optional) Check status LED (section 6)! If ignition is on the red light changes to green
indicating proper vehicle J1708 polarity
10. Screws must be fixed tightly. Make sure vehicle J1708 wires are not pinched!

5 Checking the proper operation
•Turn ignition on
•LED must light green (see section 6, LED status!)
•Green light indicates data reception. To make sure data received correctly check
Inventure FMS Gateway LED status / your telematic device function connected with
Inventure CL-J1708.
•Output data can be checked with any PC J1708 Tool (optional)

6 Operating states
The Inventure CL-J1708 has a status LED on the back of the enclosure which indicates the
current operational mode.
Table 1. The states of the status LED:
Status
Status LED
Standby (in case no J1708 communication for at least 2 seconds)
red
No communication, or no power supply
no light

Figure 5. Short explanation of color signs, printed on the device label.
6.1 Description of the states
•Standby (red light):
•The device goes to this low consumption mode 2 seconds after ending communication
on vehicle J1708 bus, or after power on.
•No light on LED:
•No communication (up to 2 seconds then device goes to standby mode)
•No power supply, or incorrect power polarity.
•J1708 polarity error (orange LED):
•Reversed J1708 High and Low wires
•Overheating (alternating orange/green or orange/red)
oTemperature is too high inside the box (75°C)
Possible reasons:
▪Heat in the environment
▪Bus overload or multiple terminating resistor or short circuit on Inventure CL-
J1708 output
