Adapter som omvandlare RS232/422/485 till CAN Bus samt CAN Bus till RS232/422/485. 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. The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network by this converter. Programmable RS-232/422/485 devices can use the serial port to connect to the CAN network via this module. In order to use the CAN network with traditional RS-232/422/485 devices, we provide a way to achieve this purpose. The module is designed to unleash the power of CAN bus via RS-232 communication method. It accurately converts messages between CAN and RS-232/422/485 networks. This module let you to communicate with CAN devices easily from any PC or devices with RS-232/422/485 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.
