1.3. Connection - Video-Interface
The video-interface converts the connected after-market sources video signals into an RGB
digital signal which is inserted in the factory monitor using separate trigger options and it
reads vehicle’s digital signals out of the vehicle’s CAN-bus and converts them for the video
interface.
1.4. Settings of the 8 Dip switches (black)
Some settings have to be selected by the 8 dip-switches at the
video-interface. Dip position down is ON and position up is OFF.
See the following chapters for detailed information.
After each Dip-switch-change a power-reset of the Can-box has to be performed!

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 a final installation, we recommend a test-run to ensure the compatibility of the
vehicle and the interface. Due to changes in the production of the vehicle manufacturer
there’s always a possibility of incompatibility.

2.3.1. Warning notes, concerning the installation of ribbon cables
1) The contacting ends of ribbon cables always have to be installed in a straight and
precise 180° position to the connector. Each deviation from a perfect contact position will
curse faulty contact and even danger of short circuit
2) The ribbon cable’s contacting side always has to correspond to the contacting side of
the connector, concerning the mounting position.
3) Avoid cable contusion or cable injury caused by sharp-edged metal.

2.6. Connecting the Video sources
It is possible to connect two after-market Video-sources and one after-market rear-view
camera to the video-interface.
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.
Connect the female 12pin connector of the 12pin interface cable to the male 12pin
connector of the video-interface.
Connect the video RCA of the video source 1 and 2 to the female RCA connector
“Video IN1” and ”Video IN 2” of the 12pin interface cable.

2.6.1. Audio insertion
This interface is only able to insert video signals into the factory infotainment. If an AV-
source is connected, the audio insertion has to be done by the factory audio 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,
additional electronic is necessary to switch the audio signals.
2.6.2. 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 12pin
cable should carry +12V while the reverse gear is engaged. See the following illustration for
the according connection.
Note: Do not forget to set dip5 of the video-interface to ON before testing.

Version 30.01.2020 HW: CAM(V97) CI-RL3-UCON8-LV
Page16
2.6.2.1. Case 1: Video interface receives the reverse gear signal
If the interface delivers +12V on the green output wire of the 12pin interface cable while
reverse gear is engaged, the video interface will automatically switch to the rear-view
camera input “Camera IN” while the reverse gear is engaged.
The 12 V power supply for the rear-view camera (max 3A) should be taken from the
green wire of the 20pin cable to avoid an unnecessary permanent power supply to
the camera electronic.
For the operation, both green cables “Reverse IN” and “Reverse OUT” have to stay
connected.

Version 30.01.2020 HW: CAM(V97) CI-RL3-UCON8-LV
Page17
2.6.2.2. Case 2: Interface does not receive any reverse gear signal
If the video interface does not deliver +12V on the green wire 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.
Disconnect the green cable’s pre-connected male- and female connectors of the
20pin cable and connect the green input cable “Reverse-IN” to the output connector
(87) of the relay.
Note: Not least to avoid short circuits, the best solution should be, to crimp a male
4mm connector to the relay’s output cable and connect it to the green cable’s female
4mm connector. The output-cable “Reverse-OUT” remains disconnected as it’s out of
function.
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 “Reverse-IN” cable before.
Connect permanent power / 12V to the relay’s input connector (30).

2.7. Connection video-interface - keypad
Connect the keypad’s female 4pin connector to the video-interface’s male 4pin
connector.
Note: Even if the switching through several video sources by the keypad mightn’t be
required, the invisible connection and availability is strongly recommended.

2.8. Picture settings
The picture settings can be adjusted by the 3 buttons on the video-interface. Press the
MENU button to open the OSD settings menu. To switch to the next menu item, pressing UP
and DOWN will change the selected value. The buttons are embedded in the housing to
avoid accidental changes during or after installation. The picture settings have to be done
separately, AV1 and AV2 while the corresponding input is selected and visible on the
monitor.
Note: The OSD menu is only shown when a working video source is connected to the
selected video-input of the interface.
The following settings are available:

3. Interface operation
The interface’s enabled inputs can be switched by the external keypad.
Each press of the external keypad switches the input from factory mode to the inserted
video sources. If, by dip switch setting, all inputs are enabled, the order is the following:
Factory video  video IN1  video IN2  factory video  …
By dip switch deactivated inputs will be skipped. If an audio switch has been connected in
the system, also the audio signal will be switched when switching from video IN1 to video
IN2
