CAN (Controller Area Network) is a serial bus system especially suited to structure intelligent industry devices networks and build smart automatic control systems. The I-7565 is a cost-efficient device for coupling the CAN-bus to the PC using the standard USB interface by the MS-Windows 98, Me, 2000, XP, Win 7 and Win 10 operating systems. If you establish the connection between the I-7565 and the PC during the runtime of the computer, the PC automatically loads the relevant device driver (hot plug & play).

    The following figure shows the application architecture for I-7565 modules. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by the I-7565 Converter. This module let you to communicate with CAN devices easily from PC with USB interface.

    3000V isolation on CAN side
    The CAN port of I-7565 is an isolated with 3000V isolation. This isolation can protect the local devices from the damage signal coming from CAN network.

    Watchdog inside
    The I-7565 Watchdog is a hardware reset circuit to monitor the I-7565’s operation status. When working in harsh or noisy environment, the I-7565 may be down by the external signal. The circuit may let the I-7565 to work continuously and never halt.

    Power and Error indicator display
    There are two indicators on the I-7565.The power indicator can help user to check whether the I-7565 is standby or transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the I-7565.
