4.2. Power and Vehicle Network Connections

The ValueCAN 4-4 is powered exclusively from the 5V USB connection.

The ValueCAN 4-2EL requires external power.

Network connections to vehicles or test benches are made through the OBD2-II, DB26HD, DB9 or DB25 connections. CAN termination is integrated into the ValueCAN4-X and can be enabled from the VSpy Hardware Setup/neoVI Explorer software interface.

Caution

Caution: The ValueCAN4-X can only be powered via the USB cable.

Caution

Caution: CoreMini scripts run when the device is powered and not connected to a PC’s USB port (that is, enumerated). Therefore to run a script stand alone, it is recommended to use a power-only USB cable to prevent enumeration. Using a charger or power pack to power the ValueCAN4-X will also work

4.3. PC Connection

Connect the USB Type A/USB C to USB port on the PC. A powered USB hub can be used to connect the ValueCAN4-X, but performance varies due to the quality of the hub and its ability to provide power. We recommend a direct connection to a native USB port unless unavoidable. If a USB hub must be used, make sure to use a high-power USB hub and test the hub with the ValueCAN4-X before use.
