Embedded CAN module CAN to RS232 RS485 TTL
CAN is recognized as stable and reliable mode of communication is widely used in fire safety and security, intelligent building, hotel door locks, mine communications, shipping and other applications.
The system uses automotive-grade CPU, better protect its stability.
Embedded CAN to CAN module UART can help users quickly achieve a CAN-bus communication interface apparatus, instrumentation, project design.
8bit microprocessor integrated module, CAN controller, CAN transceiver, the bus protection in one, all the components arranged in a miniature package within the module, the user only needs to know the RS232 communications can be realized CAN communication.
Provide PC designed to work in a transparent data transfer mode and transparent mode.
UART for TTL level output, RS232 or RS485, the corresponding order model CAN-module-ttl / rs232 / 485
1.1 Introduction
NE-CM320 is a cheap and efficient embedded CAN to RS232, RS232 to CAN devices. 1 Road CAN2.0A / B port, 1 RS232 port to achieve the CAN-bus and RS232 full-duplex bi-directional data between the port forwarding.
The product is modular in design, small size, the interface pin less, simple features, user-friendly embedded devices with UART interface, the hardware structure without changing the original premise of the CAN-bus communication device to obtain interfaces to achieve devices with UART and CAN-bus network between the data communication.
