5.2.2 Peds in DZ and Peds FCW and FCW On
Type: bool, unsigned int
Meaning: Peds in DZ (Danger Zone)
1= Pedestrian in DZ/warning on pedestrian/waning (FCW) on vehicle
0= Pedestrian not in DZ/no warning
5.2.3 Time Indicator
Meaning:
When value is “00” Day is indicated.
When value is “01” Dusk is indicated
When value is “10” Night is indicated
5.2.4 Error Valid & Error Code
Type: bool, unsigned int
Meaning: When Error Valid bit is on, the Error Code filed will contain an error code, as indicated in
the User Manual.
5.2.5 Zero speed
Type: bool
Meaning: Host vehicle is stopped
5.2.6 Headway Valid
Type: bool
Meaning: When CIPV is detected Headway Valid is ON (bit=1)
5.2.7 Headway measurement
Type: unsigned char
Unit: 0.1 s (unit value is presented in Hex –ex: 1.0 = 0A)
Range: 0 … 9.9
5.2.8 LDW Off
Type: bool
Meaning: Lane Departure Warnings are disabled when the value is equal 1 (due to low speed or
configuration).

5.2.9 Left/Right LDW On
Type: bool
Meaning: Indicator of Left/Right LDW event.
Note: The LDW will be ON for 5 consecutive frames, no matter how long the event really is
5.2.10 Maintenance
Type: bool
Meaning: Indicator of internal error. See User Manual.
5.2.11 Failsafe
Type: bool
Meaning: Indicator of one of the internal Failsafe modes (blur image, saturated image, low sun,
partial blockage, partial transparent)
5.2.12 FCW On
Type: bool
Meaning: Indicator of FCW event.
Note: The FCW will be ON for the entire warning length.
5.2.13 TSR Enabled
Type: bool
Meaning: TSR feature is ON.
5.2.14 HW Repeatable enabled
Type: bool
Meaning: HW Repeatable feature is ON if configured (1=ON)
Note: HW Repeatable configuration is possible only during system Configuration/Installation process
(via Mobileye Setup Wizard).

5.2.15 Headway Warning Level
Type: unsigned char
Unit: HW Level (0-2).
Note: changes according to warning scheme setup. Default values:
oWhen no CIPV is present, HW Level = 0
(When NO vehicle is detected “0” is indicated).
oWhen a CIPV is present with HW > HW Config, HW Level = 1
(When HW Distance is > then the configured HW “1” is indicated. This indicates a Green Car Icon on
the Display unit).
oWhen a CIPV is present with HW ≤ HW Config, HW Level = 2
(When HW Distance is ≤ then the configured HW “2” is indicated. This indicates a Red Car Icon on the
Display unit).
oWhen a CIPV is present with HW < 0.6, HW Level = 2 ()
When HW Distance is < 0.6 HW seconds “2” is indicated. This indicates a Red Car Icon on the Display
unit (regardless of your HW configuration).
5.2.16 TSR Warning Level
Every time the vehicle speed is greater than the Legal Speed limit Sign by 5 (km/h or mph) then a BIT
will turn ON and will grow by +1 with every 5 (km/h or mph) growth. This is limited up to 35 (km/h or
mph)
When Speed <= road speed, TSR Warning level= 0
When Speed > road speed + [0-5kmh], TSR Warning level= 1
When Speed > road speed + [5-10kmh], TSR Warning level= 2
When Speed > road speed + [10-15kmh], TSR Warning level= 3
When Speed > road speed + [15-20kmh], TSR Warning level= 4
When Speed > road speed + [20-25kmh], TSR Warning level= 5
When Speed > road speed + [25-30kmh], TSR Warning level= 6
When Speed > road speed + [25-30kmh], TSR Warning level= 6
When Speed > road speed + [30-35kmh], TSR Warning level= 7
When Speed > road speed + 35, TSR Warning level= 7

5.2.17 Tamper Alert
Type: bool
Meaning:
When 0 = No Tamper Alert
When 1 = Tamper Alert is ON
Note: Tamper Alert will be activated if there is no vehicle or lane detection for duration of 10
minutes. Tamper Alert is active above 15 km/h (9 mph).
Details:
Tamper Alert will function when:
-If speed >= 55 km/h, and there is No Lane and Vehicle detection for a duration of 10 minutes.
If a Lane or Vehicle are detected in any Frame during the 10 minutes duration, the 10 minutes
duration will be prolonged by a factor of the “Time past until the detected Frame divided by 2.
For example, if there was no detection for 9 minutes and then a Lane was detected in 1 frame,
the 10 minutes duration will resume from 4.5 minutes, meaning the time left for receiving the
Tamper alert is now 5.5 minutes.
-If speed >= 15 km/h, and there is No Vehicle detection of any kind for a duration of 10 minutes.
From the moment Wipers are active, the 10 minutes duration will be multiplied by 2 to 20 minutes.

6 Connection Schematic

7 Test phase - Optional
The purpose of this section is to test and validate the data output from the CAN to RS232
converter.
We have 2 options for testing the data output:
1) Using a basic application such as Termite (V3.2) which is available online for free.
2) Via the existing mini USB port at the CAN to RS232 converter
7.1 Connection Schematic –via RS232 to USB adapter

7.2 Application Settings
1. Download and install the Termite application
2. Download drivers
3. Open the application
4. Change to the default baud rate of the Mobileye CAN to RS232 converter to 115200
click "OK" to save the settings
5. The following window will appear and show a ASCII code reflect the CAN message
id 0x700
Check the CAN output according to the table in section 5.2

7.3 Connection Schematic –via existing Mini USB plug
For application setting see section 7.2 and follow the instruction at this section.
