3.3. USB and optional IR-remote control set

Connect USB-connector of USB-installation socket USBC-EXT to USB-socket of USB­Box USBC-M511 and install the USBC-EXT socket in a well accessible location, e.g. the
glove-box. Make sure there is enough space to load USB-media.

Installation socket for the connection of USB-media.

The USB-IRSET consists of the external C3C-SENSOR IR-sensor and the USBC-RC IR­remote control and can be used to control the usbLOGiC’s internal USB functions
additionally to the control through the navigations buttons. Connect the C3C­SENSOR to the female black/red/blue 3pin AMP connector of harness C3C-AVIR and
locate the sensor in an accessible place.

3.4. Connecting peripheral devices

It is possible to connect an after-market AV-source and rear-seat-entertainment to the
usbLOGiC, as well as to code the Comand’s rear-view camera input for an after-market or
factory rear-view camera.

Before final installation of the peripheral devices, we recommend to test-run the usbLOGiC
functions to detect incompatibility of vehicle, navigation, factory accessories or peripheral
devices as soon as possible.

Version 22.12.2011 USB-NTG25

Page8

3.4.1. AV-source

The usbLOGiC has the possibility to connect and remotely control by navigation buttons a
pre-programmed device. The device list in the device control table (Appendix A) shows the
pre-programmed remote channels and the related IR-remote cables STA-xxx which must be
ordered separately for the control of the device.

Using the respective STA-xxx IR-control cable, interconnect the yellow female 3pin
AMP connector of harness C3C-AVIR and the IR-port of the AV-source.

Using an RCA-cable, interconnect the female RCA-port AV-IN of the USB-box
USBC-M511 with the AV-output of the AV-source.

The pink ACC-output wire (+12V max 1A) of harness C3C-MBN25 can be connected to
the ACC-input wires of the connected device to switch it on. It carries +12V when the
Comand is running.

3.4.2. Installing AV-source’s IR-sensor additionally

Additionally to the control via OEM navigation, it is possible to install the original IR-sensor
of a connected device. By using the respective Y-adapter (e.g. STA-Y35MM or STA-RJ12) for
the IR-Port of the connected device, the controls of navigation AND device’s IR-sensor can be
connected and used simultaneously. Installation of the IR-sensor is recommended as the
controls via navigation are limited, and not all functions may be covered.

3.4.3. After-market rear-view camera

Connect the video RCA of the after-market rear-view camera to the female
RCA- connector of optionally available adapter CAB-TVAS20.

Connect female Fakra of adapter CAB-TVAS20 to green male Fakra of Comand.

Connect the green wire of C3C-MBN25 to the camera power supply (+12V max 1A)
The green wire is high (+12V) when reverse gear is engaged.

3.4.4. After-market rear-seat-entertainment

Using RCA-cables, connect the rear-seat-entertainment to the female RCA-connector
VIDEO OUT of USB-box USBC-M511.

Note: As the output is a full output, not shared with the video signal for the
navigation system, splitting the video with an RCA Y-cable might give a good enough
picture for two rear-seat-entertainment monitors. If not, or if connecting more than
two monitors, use a video splitter.
