2. Installation
2.1 Power supply
GCAN-401 support 9~30V wide range of power supply, so it can be applied to most of the industrial field and the car interior, it is power supply terminals defined as shown in table 2.1.

2.2 Connect to CAN-Bus
GCAN-401 has one CAN-Bus by a plug type terminal leads, this CAN-Bus channels can connect to CAN-Bus network or devices. Terminal pin definition as table 2.2.

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.
