2 Installation

This chapter describes how to connect the USBCAN adapter with a computer and the precautions when connecting the USBCAN adapter with a computer for the first time.

2.1 Driver and software installation

USB power supply mode is suitable for the most applications, such as: when USBCAN-OBD is the only device in USB port.

2.2.2 External power supply mode (only the USBCAN-II Pro support)

External power supply mode is suitable for the USB port using an USB HUB and have already connect multiple USB device, this will lead to the adapter lack ofelectricity supply.


2.3 Connect to CAN-Bus

USBCAN-OBD has one CAN-Bus by OBD-II port, this CAN-Bus channels can connect to CAN-Bus network or devices. OBD-II pin definition as Table 2.1 below.



Note: In practical use, most of the time just connected the CAN_H to CAN_H and CAN_L connected to CAN_L then communication can be realized
