1.4. Connection - Video-Interface
The video-interface converts the video signals of connected after-market sources in a factory
monitor compatible picture signal which is inserted in the factory monitor, by using separate
trigger options. Further it reads the vehicle’s digital signals out of the vehicle’s CAN-bus and
converts them for the video interface.

1.5.1. Enabling the interface’s video inputs AV1-R and AV2-L (dip 1-2)
Only the enabled video inputs can be accessed by switching through the interface’s video
sources. It is recommended to enable only the required inputs. Then the disabled inputs will
be skipped while switching through the video interfaces inputs.
1.5.2. Activating –front camera back-switching V3 Front (dip 3)
If set to ON, the interface switches for 10, 15 or 20 seconds from the rear-view camera to
the front camera input after having disengaged the reverse gear. In addition, a manual
switch-over to the front camera input is possible via keypad (short press) from any image
mode.
To power up the front cam, the video interfaces’ green wire „Reverse-Out“ will supply +12V
(max 3A) with engaging the reverse gear and additionally 10, 15 or 20 more seconds power
delay for the time of the front camera’s back-switching after the reverse gear has been
disengaged. Furthermore, the green wire’s power supply for the front cam becomes active
with manually front camera switching (short press of the external keypad).
1.5.3. Activation signal –video sources (dip 4)
For source activation via CAN, dip switch position ON must be selected.
For manual source activation via trigger wires, the switch position must be OFF.
1.5.4. Rear-view camera settings (dip 5)
If set to OFF, the interface switches to factory picture while the reverse gear is engaged to
display factory rear-view camera or factory optical park system picture.
If set to ON, the interface switches to its rear-view camera input while the reverse gear is
engaged.
1.5.5. Activating the guidelines (dip6)
If set to ON, the guide lines will be shown on the display.
If set to OFF, the guide lines won’t be visible on the display.
Note: The display of the guidelines only works with simultaneous PDC display (Dip8 = ON).
If there is no communication between interface and the vehicle`s CAN-bus (several vehicles
aren’t compatible), the reverse gear guide-lines can`t be shown during the vehicle’s
operation, even if they once appear after having switched the system to powerless!

1.5.6. Activating the factory PDC display (Dip-8)
Dip 8 is used to activate the factory PDC display (if available) when retrofitting an after-
market rear view camera. When dip switch is set to OFF, the factory PDC display is shown on
the right side of the display. With Dip switch position ON, the factory PDC display is not
shown.
Note: Dip 7 is out of function and has to be set to OFF.
After each Dip-switch-change a power-reset of the interface box has to be performed!
1.6. Settings of the 4 Dip switches (CAN function - red)
In contrast to the 8-dip switches
dip position up = ON and position down = OFF!
After each Dip-switch-change a power-reset of the Can-box has to be performed!
2. Installation
Switch off the ignition and disconnect the vehicle’s battery! The interface needs a
permanent 12V source. If -according to factory rules- a disconnection of the battery has to
be avoided, it should be sufficient to use the vehicle’s sleep-mode. In case, the sleep-mode
doesn’t succeed, the battery has to be disconnected with a resistor lead.
The Interface needs a permanent power supply! If power isn’t directly taken from the
battery, the connection’s power has to be checked for being start-up proven and
permanent.
Before the final installation, we recommend a test-run of the interface. Due to changes in
the production of the vehicle manufacturer, there’s always the possibility of
incompatibility.
2.1. Place of installation –video-interface
The video-interface is performed to be installed at the head unit’s rear side.

Version 03.05.2021 HW: BOT(V40)(V54) CI-RL4-NAC12
Page17
2.5.1. Audio insertion
This interface can only insert video signals into the factory infotainment. If an AV source is
connected, the audio insertion has to be performed by a factory aux input or an FM
modulator. The inserted video-signal can be activated simultaneously to each audio-mode of
the factory infotainment.
If 2 AV-sources shall be connected to the infotainment, for audio switching an additional
electronic part is required.
2.5.2. After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the video-interface
is not compatible with. Therefore, there are two different ways of installation. If the video
interface receives a signal of the reverse gear, the green wire “Reverse-OUT” of the 20pin
cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of the video-interface to ON before testing.
2.5.2.1. Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface carries +12V on the green wire “Reverse-OUT” of the 20pin cable
when reverse gear is engaged, it will also automatically be switched to the rear-view camera
input „V4 Reverse“while reverse gear is engaged.
The 12 V power supply for the rear-view camera (max 3A) has to be taken from the
green wire “Reverse-OUT”of the 20pin cable to avoid an unnecessary, permanent
power supply to the camera electronic.

Version 03.05.2021 HW: BOT(V40)(V54) CI-RL4-NAC12
Page18
2.5.2.2. Case 2: Video interface does not receive the reverse gear signal
If the video interface does not carry +12V on the green wire „Reverse-OUT“of the 20pin
cable when reverse gear is engaged (not all vehicles are compatible), an external switching
signal from the reverse gear light is required. As the reverse gear light’s power supply isn’t
voltage-stable all the time, an ordinary open relay (e.g AC-RW-1230 with wiring AC-RS5) or
filter (e.g. AC-PNF-RVC) is required. The diagram below shows the connection type of the
relay.
Connect the green input cable “Trig.-REAR”to the output connector (87) of the relay.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
Connect the output connector (87) of the relay to the rear-view camera’s power-
cable, like you did it to the green “Trig.-REAR” cable before.
Connect permanent power / 12V to the relay’s input connector (30).
Note: If, due to a missing CAN communication, interface has been connected the analogue
way, the green wire’s connection has also to be done as shown in the picture above.
For analogue connection, dont forget to set dip4 to OFF!

Version 03.05.2021 HW: BOT(V40)(V54) CI-RL4-NAC12
Page19
2.5.3. After-market front camera
To display the images from the front camera camera, the video interface also receives the
data from the vehicle CAN bus. If, due to missing CAN bus data (as not all vehicles are
compatible), the analogue power connection was previously made, the corresponding
manual input signal by „Trig-FRONT“wire is also required here.
For analogue connection, dont forget to set dip4 to OFF.
The green power supply output „Reverse-Out“ can be used to power a front camera.
If Dip 1 is set to ON (of the black 8 dips), the power supply output supplies +12V (max
3A) when the reverse gear is engaged …
and additionally 10, 15 or 20 seconds
delay after reverse gear is
disengaged for the front camera.
Note: In addition, a manual switch-over to the front camera input is possible via keypad
(short press) from any image mode. The power supply output supplies +12V then, too (if Dip
3 is set to ON and the front camera input is selected).

Version 03.05.2021 HW: BOT(V40)(V54) CI-RL4-NAC12
Page20
2.5.4. After-market mirror cameras
To display the images from the left and right mirror camera, the video interface also receives
the data from the vehicle CAN bus. If, due to missing CAN bus data (as not all vehicles are
compatible), the analogue power connection was previously made, the corresponding
manual input signals Trig-RIGHT/Trig-LEFT are also required here.
For analogue connection, dont forget to set dip4 to OFF!
Power is supplied to the mirror cameras via the red cable „ACC-out“.
Attention: To energize the mirror camaras, only continuous current-resistant cameras may
be connected to the red line „ACC-out“, as they would otherwise be damaged.
Our following cameras are among others resistant to continuous current:
CAM-E-B168
CAM-E-B180
CAM-E-b113
