6. Equipment usage

The USB interface of ECAN-U01 conforms to the USB2.0 full-speed protocol specification, and can communicate with

PCs with USB1.1 and USB2.0 standards.

6.1.1. USB Bus Power Mode

The USB bus powered mode is suitable for most applications, for example, when the ECAN-U01 is the only device

connected to the USB port. Connect the PC and ECAN-U01 directly through the supplied USB cable, and supply +5V

power to ECAN-U01 from the USB cable . At this time, the indicators PWR and Work are on, indicating that the device

is working normally and is in the state to be connected.

External power supply mode

6.1.2.

The external power supply mode is suitable for the occasions where the PC uses a USB bus hub ( HUB ), or has

connected multiple USB terminal devices, so that the USB port cannot provide enough current to the ECAN-U01 .

Use an external power supply (DC8-28V) to connect to the power socket of ECAN-U01 , at this time the indicators

PWR and Work are on ; then connect the PC and ECAN-U01 through the supplied USB cable, ECAN-U01 can work

normally.

When ECAN-U01 is connected to the CAN bus, you only need to connect CAN_H to CAN_H and CAN_L to

CAN_L to establish communication.

The CAN-bus network adopts a linear topology, and the two farthest terminals of the bus need to be installed with

120 Ω terminal resistance; if the number of nodes is greater than 2 , the intermediate node does not need to be installed

with a 120 Ω terminal resistance. For branch connections, its length should not exceed 3 meters. The connection of

CAN-bus is shown in the figure.
