1.3. Boxes and connectors –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.

2. Installation
To install the interface, first switch off the ignition and disconnect the vehicle’s battery.
Please read the owner`s manual of the car, regarding the battery`s disconnection! If
required, enable the car`s Sleep-mode (hibernation mode)
In case the sleep-mode does not succeed, the disconnection of the battery can be done
with a resistor lead.
If the necessary stabilized power supply for the interface is not taken directly from the
battery, the chosen connection has to be checked for being constantly stabile.
The interface needs a permanent 12V source!
2.1. Place of installation
The interface is supposed to be installed at a suitable location behind the vehicle`s head-
unit.

2.5. Connection - video sources
It is possible to connect an after-market rear-view camera, an after-market front camera and
two more video sources to the video-interface.
Before a final installation of the video sources, we recommend a test-run to ensure the
compatibility of vehicle and interface. Due to changes in the production of the vehicle
manufacturer there’s always a possibility of incompatibility.
Connect the 12pin interface cable’s female 12pin connector to the male 12pin connector of
the video-interface.

2.5.1. 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.
2.5.2. After-market front camera
The red power supply output ACC/front cam out 12V (max 3A) can be used to power
a front camera. If Dip 1 is set to ON (black 8 dips), the power supply output gives
+12V (max 3A) when reverse gear is engaged …
incl. 10, 15 or 20 seconds delay after reverse gear is
disengaged (refer also to chapter “picture settings).
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 gives +12V then, as well (if Dip 1 is set
to ON and the front camera input is selected).
Attention: A long press of the external keypad push button will switch the interface to the
next source.

Version 27.08.2021 HW: CAM(V100)/(V20) RL4-MIB100
Page18
2.5.3. 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 video interface’s dip5 to ON before testing.
2.5.3.1. Case 1: 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 “V4 Reverse”while the reverse gear is engaged.
Additionally, the +12V (max. 3A) power supply for the rear-view camera can be taken from
the green wire of the 12pin interface cable.

Version 27.08.2021 HW: CAM(V100)/(V20) RL4-MIB100
Page19
2.5.3.2. Case 2: Interface does not receive the reverse gear signal
If the video interface does not deliver +12V on the green wire of the 12pin 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-
stabile 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 preconnected male- and female connectors of the 12pin
interface cable and connect the green input cable “Reverse-IN” to the output
connector (87) of the relay.
Note: Last but not lot 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 stabile and permanent +12V to the relay’s input connector (30).

Version 27.08.2021 HW: CAM(V100)/(V20) RL4-MIB100

2.6. Connection - video-interface and keypad
Connect the female 4pin connector of the keypad to the male 4pin connector of the
12pin interface cable.
Note: Even if switching through several video sources by the keypad mightn’t be
required, the invisible connection and availability is strongly recommended.
