2.8. 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.

Connect the front camera’s video RCA connector to the 12pin interface cable’s female
RCA connector „Front V3“.

Connect the video RCA of the AV source 1 and 2 to the 12pin interface cable’s female RCA

connector “Left (V1)” and ”Right (V2)”.

Version 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP

2.8.1. 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 2 AV sources shall be connected to the infotainment,
additional electronic is necessary to switch the audio signals.

2.8.2. 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 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP

Page18

2.8.3. After-market rear-view camera:

Some vehicles have a different reverse gear code on the CAN-bus which doesn’t
communicate with the interface’s CAN. In this case there are two different ways of
installation. If the interface’s CAN is able to detect an enabled vehicle’s reverse gear, the
green wire of the 6pin to 12pin cable should carry +12V while the reverse gear is engaged.

Note: Do not forget to set dip5 of video-interface to ON before testing.

2.8.3.1. Case 1: Interface receives the reverse gear signal

If the interface receives +12V on the green 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) has to be taken from the
12pin interface cabl’s green wire “Reverse-OUT” to avoid an unnecessary,
permanent power supply to the camera electronic.
Both green cables “Reverse IN” and “Reverse OUT” have to remain connected.

Version 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP

Page19

2.8.3.2. Case 2: Interface does not receive the reverse gear signal

If the video interface does not receive +12V on the green wire of the 12pin interface 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
12pin 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 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP

Page20

2.9. 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 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP

Page21

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.
