1 Introduction
The EyeCAN cable is a one channel USB interface for CAN bus. It is used for installation and
calibration of Mobileye systems, as well as CAN-bus analysis purposes (sniffing) and Mobileye
firmware upgrades.
The EyeCAN uses USB 2.0 and handles messages with 11-bit (CAN 2.0A) and 29-bit (CAN
2.0B) identifiers. The EyeCAN can transmit* and receive remote frames.
The Mobileye EyeCAN also has the following features:
EyeCAN is a reliable low cost product developed and manufactured by Mobileye.
The EyeCAN supports full speed USB interface for CAN with high performance.
Loss free transmission and reception of standard and extended CAN messages on
the CAN bus is transmitted with a time stamp precision of 100 microseconds.
The low current consumption, 70 mA, reduces the power drain from your laptop.
Application Areas: Mobileye Setup Wizard (from v2.1.7), CANsee (from v1.8), AM
QC Application (from v2.8)
2 Device Components
The Mobileye EyeCAN cable kit is composed of 3 components:
1 - The EyeCAN USB cable
2 - EyeCAN / LOG Y-cable (CAB000091)
3 - EyeCAN Sniffer Cable (CAB000092)
123
Items 1 and 2 are used for Mobileye system Calibration and updating Firmware versions (using
the AM QC Application).
Item 1 and 3 are used for CAN sniffing (using the CANsee application).
More detailed information can be found in the chapters ahead and in the connections schemes
in chapter 10.
* EyeCAN does not transmit CAN messages to the vehicle CAN bus in Silent mode (default)

3 Power
The EyeCAN is powered through the USB connector. The host must supply 5V DC, as per
the USB specification.
4 LEDs
The EyeCAN has four LEDs. Their functions are shown in Table 1.

5 USB connector
The EyeCAN may be connected to any free USB socket on the host computer. Power does
not have to be turned off before inserting or removing the device. It is good practice,
though, to exit all applications using the CAN hardware before removing the EyeCAN.
The USB cable included with the delivery is approx. 140 centimeters long and is
permanently attached to the EyeCAN. If a longer cable is desired, use a standard extension
cable with a type ―A‖ receptacle (Figure 4) at one end and a type ―A‖ plug (Figure 5) at
the other end. Do not extend the cable to more than 5 meters without an active extender.
With an active extender, the maximum length is 25 meters.

7 EyeCAN Sniffer cable (CAB000092)
7.1 EyeCAN Sniffer Cable (OBDII)
The EyeCAN Sniffer cable (CAB000092) is an additional cable Mobileye provides for CAN
Sniffing proposes. The cable is equipped with a multipurpose OBDII connector to allow a
quick connection to the vehicle’s OBDII connector and a connection to the vehicle’s CAN
interface for the following CAN-bus options:
Pins 6 and 14
Pins 3 and 11
Pin 1 (GMLAN)
The cable also has 2 free CAN cables to allow connection to vehicle’s CAN-bus wires which
are not in the OBDII connector:
White cable –CAN_H
Yellow cable –CAN_L
These cables are routed to the 6 pin Nelron connecter labeled (A 6H14L CAN A H L).
