5 Installation
5.1 Installing the Software
For the operation of the interface a driver is needed.
Windows
► Install the VCI driver (see Installation Guide VCI Driver).
Linux and Real-Time Operating Systems
► Observe information about supported operating systems and interfaces on www.ixxat.com.
5.2 Installing the Hardware
5.2.1 Connecting USB
Malfunction caused by extension cable!
According to the USB specification connect the interface directly or via an active USB hub
to the computer. Do not use an extension cable.
Insufficient power supply!
Connect the interface directly to the computer or to self-powered hubs to ensure
sufficient power supply.
The shield of the USB cable is connected to ground using a 100 nF capacitor. The shield of the
CAN connector is connected to CAN ground via a 1 MΩ resistor and a 10 nF capacitor. USB_shield
is connected to CAN_shield via a 4.7 nF capacitor. The shields of the CAN connectors of the
variants professional and automotive are connected directly together.
For non galvanic decoupled interfaces, fieldbus ground and computer ground are at the same
potential.
USB-to-CAN
Connector:
• USB cable with plug type A
• Assignment corresponds to USB 2.0 standard.
► Make sure that the VCI driver is installed.
► Plug the USB connector in the USB port of computer.
→ Windows automatically finds and installs the hardware.

5.2.3 Connecting the CAN Fieldbus
The assignment of the fieldbus connectors (D-Sub 9 and RJ45) is in accordance to CiA 303-1.
The shield of the CAN connector is connected to CAN ground via a 1 MΩ resistor and a 10 nF
capacitor. USB_shield is connected to CAN_shield via a 4.7 nF capacitor. The shields of the CAN
connectors of the variants professional and automotive are connected directly together.
For non galvanic decoupled interfaces, fieldbus ground and computer ground are at the same
potential.
For best noise immunity connect the shields of the CAN cables directly to the device ground.

5.2.4 Connecting the LIN Fieldbus
LIN functionality is exclusively available on the USB-to-CANV2automotive.
Power consumption is limited by a 1 kΩ resistor.
The LIN interface can receive and transmit LIN frames according to LIN specification V1.3 and
V2.0/2.1. The LIN interface can be configured as LIN master.
A 1 kΩ pull-up resistor is automatically activated in LIN Master mode and automatically
deactivated in LIN Slave mode. External pull-up resistors are not necessary.
► To use the LIN interface connect a voltage of 12 V DC (voltage range 8 to 18 V DC) to pin
VBAT
To ensure successful transmission of LIN messages:
► Connect external voltage before LIN messages are transmitted.
► Make sure, that the external voltage is not switched off and on during operating in LIN
mode.
