Adapter som omvandlare USB till CAN Bus. CAN bus är ett seriellt gränssnitt som oftast används i fordonsmiljö men ibland även i industriella sammanhang. Denna adapter gör det enkelt att ansluta en modern utrustning till CAN bus interface.
CAN (Controller Area Network) is a serial bus system especially suited to structure intelligent industry devices networks and build smart automatic control systems. This adapter is a cost-efficient device for coupling the CAN-bus to the PC using the standard USB interface. Nowadays the interface is present in every new PC and is supported by the MS-Windows 98, Me, 2000 and XP operating systems. If you establish the connection between this module 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 this modules. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by this 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 this adapter is an isolated with 3000V isolation. This isolation can protect the local devices from the damage signal coming from CAN network.
Watchdog inside
This adapters Watchdog is a hardware reset circuit to monitor the modules operation status. When working in harsh or noisy environment, the adapter may be down by the external signal. The circuit may let the adapter to work continuously and never halt.
Power and Error indicator display
There are two indicators on this module.The power indicator can help user to check whether the module is standby or transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the module.
