Caution

Caution: The ValueCAN 4-1 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 ValueCAN 4-1 will also work

4.3. PC Connection

Connect the USB Type A/Type C to USB port on the PC. It is possible to use a powered USB hub to connect the ValueCAN 4-1, but performance varies due to the quality of the hub and its ability to provide power. Make sure to use a high-power USB hub and test the hub with the ValueCAN 4-1 before use.
