2.10. Connecting 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 the final installation, we recommend a test-run to detect a incompatibility 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.
Connect the video RCA of the Rear-view camera to the 12pin interface cable’s female
RCA connector „Reverse V4.

connector “Left (V1)” and ”Right (V2)”.
Version 25:11.2020 HW CANM(V100)/(V36) RL4-UCON8-CP
Page19
2.10.1. Audio-insertion
This interface is only able to insert video signals into the factory infotainment. If an AVsource 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 audiomode of the factory infotainment. If two AV sources shall be connected to the infotainment,
additional electronic is necessary to switch the audio signals.
2.10.2. 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 seconds delay after reverse gear
is disengaged.
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 25:11.2020 HW CANM(V100)/(V36) RL4-UCON8-CP
Page20
2.10.3. 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 dip5 of the video-interface to ON before testing.
2.10.3.1. Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface receives +12V on the green wire of the 20pin cable when reverse
gear is engaged, it will automatically be switched to the rear-view camera input “Camera IN”
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 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 remain
onnected.
Version 25:11.2020 HW CANM(V100)/(V36) RL4-UCON8-CP
Page21
2.10.3.2. ACase 2: Video interface does not receive the reverse gear signal
If the video interface does not receive +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 voltagestable 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 powercable, like you did it to the green “Reverse-IN” cable before.
Connect permanent power / 12V to the relay’s input connector (30).
Version 25:11.2020 HW CANM(V100)/(V36) RL4-UCON8-CP
Page22
2.11. Connection - external keypad
Connect the keypad’s female 4pin connector to the 12pin interface cable’s male 4pin
connector.
Note: Even if the switching through several video sources by the keypad mightn’t be
required, the keypad’s invisible connection and availability is strongly recommended.
Version 25:11.2020 HW CANM(V100)/(V36) RL4-UCON8-CP
Page23
3. Interface operation by external keypad
The interface’s external keypad can be used to switch the enabled inputs.
➢ Long press of keypad (2-3 seconds)
By long pressing the external keypad (2-3 seconds), the video interfaces witches the input
from the factory video to the inserted video sources.
Each press (approx. 2 sec) will switch to the next enabled input. If all inputs are enabled the
order is:
Factory video→ video IN1 → video IN2 → factory video →…
Disabled inputs will be skipped.
Note: The interface switches after releasing the switch (after long pressure).
➢ Short press of keypad (only if DIP 1 is set to ON)
By short pressing the external keypad, the video interfaces switches from the factory video
to the front camera input and back to factory video.

4. Picture settings
The picture settings are adjustable by the 3 push-buttons of the daughjter PCB’s menu
keypad. Press the 1. button to open the OSD settings menu or to switch to the next menu
item. By pressing the other both push buttons the selected value will be changed. To avoid
accidental changes during or after the installation, we recommend to disconnect the keypad
from the pushbutton cable after the adjustments are done. Adjustments have to be done,
while the selected input is 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.
