The can bus communications converter is called NE-CM320. It is used to help users to do the instruments’ design, which has CAN bus communication interface. This converter incorporates many things into it, for example, 8 bit micro-controller, CAN controller, the can transceiver, power supply circuit, isolation circuit, bus protection and etc.. All components are arranged in a miniature package module.
The embedded CAN bus converter can be installed to the device’s circuit board. It could be connected with the external control signal through the I / O or serial port. In many applications, the user only need to transmit the field I / O or UART data to the CAN bus network, the can bus communications converter is a reliable, rapid and convenient choice.
The NE-CM320 communications converter has the characteristics such as modular design, the compact size, a small quantity of interface pins and etc..The NE-CM320 module can make the device get CAN-bus communicate interface on the basis of not changing the original hardware structure. It makes it easy to use the NE-CM320 converter in the device, which has UART interface.Its main function is to realize the communication between the CAN bus network and the devices, which have UART interface.
The embedded CAN converter could achieve the setting of serial communication rate and CAN’s parameters. Thanks to the CAN bus advantages as below: development and maintenance of low cost, higher bus utilization, long distance transmission, high speed transmission rate, reliable error detection and handling mechanism and etc..All those advantages above make up for the deficiency of the traditional RS485 network. The Can bus communications converter helps user build the stable and efficient field bus control system. The CAN converter could be widely used on instrumentation, instrumentation, petrochemical, power monitoring, engineering machinery, automotive electronics and etc..
The Can bus communications converter includes a high performance micro-controller, the chips of Flash,RAM,EEROM and watchdog,bus driver. All these components are integrated in a 6.5 square centimeters module.
Users could operate the Can bus communications converter without knowing any CAN bus relevant knowledge. The converter helps to realize the data communications between UART equipment and CAN bus network. In addition, UART output to TTL level, the user can construct RS232 or RS485 net according to need external RS232 or RS485 transceiver.
The size of the embedded CM320 converter is only 32 mm × 20 mm x 9.5 mm, standard feet spacing 100 mil (2.54 mm), double row needles spacing 600 mil.The Can bus communications converter could be used as a DIP-28 integrated circuit. Its volume is small and function is all ready, therefore the users do not need to connect any peripheral components. This converter makes the equipment connect with CAN bus network through the UART port.
