  • Vehicle-specific Assignments CAN-bus
    Consult the vehicle-specific assignments section to ensure proper configuration based on your vehicle make and model.

Product Features

  • Conversion of digital CAN-bus signals into analogue signals ACC, speed, lights, reverse gear, park distance control (optional cable CX-LS necessary)
  • Adaptation of vehicle-specific radio ports to female ISO-connectors (for some vehicles only a universal harness with open ends available)
  • Support/Starting of factory sound systems (not at all vehicles)
  • Steering wheel control for after-market devices (optional) Alpine, Blaupunkt, Clarion, Digitaldynamic, JVC, Kenwood, Pioneer, Zenec
  • With USB update-port for software-updates by consumer

Information
Changes/updates of the vehicle’s software can cause malfunctions of the interface. We offer free software-updates for our interfaces for one year after purchase. To receive a free update, the interface must be sent in at own cost. Labor cost for and other expenses involved with the software-updates will not be refunded.

Prior to installation

Read the manual prior to installation. Technical knowledge is necessary for installation. The place of installation must be free of moisture and away from heat sources.

Delivery contents
Take down the SW-version and HW-version of the CAN-box, and store this manual for support purposes

Check compatibility of vehicle

  • The CX-401 provides depending on the vehicle ignition (I), speed signal (S), reverse gear (R), lighting (L), acoustic signal of park distance control (PDC) as an analogue signal, it powers up an existing factory sound-system (SS), allows the using of on-board computer system control (OCS) and supports the control of after market devices by steering wheel (SWC).
  • The link to the table shows which harness CX-0xx can be used for which vehicles and which functions of the CX-401 will be supported for this vehicle. https://downloads.casgermany.com/can_bus_compatibility.pdf

Setting the DIP switches
To use the steering wheel control is dependent on the manufacturer of the after-market device a device-specific IR control cable ARC-1xx needed. The DIP sitches of the CAN-box CX-401 have to be set on the manufacturer/ port.

The following table shows the IR control cable and the DIP switch settings for the supported manufacturers.

Setting of internal switch for Pioneer devices (as of HW-VER V3.0)
When the steering wheel control with a Pioneer will not work (DIP1 OFF | DIP2 ON | DIP3 ON), then open the housing of the interface and change the switch position from 5V to 3.3V.

Installation

  • Switch off ignition and disconnect the vehicle’s battery! If according to factory rules disconnecting the battery has to be avoided, it is usually sufficient to put the vehicle in sleep-mode. In case the sleep-mode does not show success, disconnect the battery with a resistor lead.
  • Place of installation of the CX-401 is usually in the radio slot on the vehicle’s radio port.

Installation with vehicle-specific harness CX-0xx

  1. Persistent current, Ground, ACC signal (Z) and lights signal (L) are pinned in the female ISO-connector of the CX-0xx. If supported by the CX-401 connect speed signal (S) and reverse gear signal (R) to the corresponding pins of the after-market device.
  2. Depending on equipment/vehicle the grey cable is occupied with the analogue phone mute signal. Connect to the corresponding pins of the after-market device.
  3. Connect vehicle’s female radio connector(s) to the corresponding male connector(s) of harness CX-0xx.
  4. Connect harness CX-0xx to CAN-Box CX-401 via 12pin Molex.
  5. Connect female ISO-connectors of harness CX-0xx to the ISO-connector of the aftermarket device.
  6. Optional: Connect IR-control input of the after-market device to the 4pin Molex IRcontrol output of CAN-box CX-401 via the optional control cable ARC-1xx.

Note for CX-035 (Ford): ACC and illumination are not digital but analogue signals on some vehicles. In this case connect ACC (Quadlock, chamber A, pin 16; pink wire) and illumination (Quadlock, chamber A, pin 13; orange wire) between female 12pin MicroFit connector and female ISO connectors, using the plugs of the harness.

Installation with universal harness CX-010

  1. Connect universal harness CX-010 according to assignment of 12pin Molex on CX- 401 to harness of the after-market device and to vehicle harness.
  2. Optional: Connect IR-control input of the after-market device to the 4pin Molex IRcontrol output of CAN-box CX-401 via the optional control cable ARC-1xx.

Installation acoustic signal of park distance control with CX-PI200 (till SW 1.1.2)

  1. Connect the black and red cable of the CX-PI200 (Piezo LSP to CX-028/CX-030/CX- 033/CX-010) into the correlative pins of the female 12pin Molex connector of harness CX-0xx:Incar-Solution-CX-401-Steering-Wheel-Control-Interface-FIG- (6)Installation acoustic signal of park distance control with CX-LS (from SW 1.1.3)
  2. Connect the black and red cable of the CX-LS (LSP to CX-028/CX-030/CX-033/CX-010) into the correlative pins of the female 12pin Molex connector of harness CX-0xx:Incar-Solution-CX-401-Steering-Wheel-Control-Interface-FIG- (7)
