1.Overview

The GCAN-305 is an embedded CANopen serial port  (UART) communication conversion module developed by Shenyang Guangcheng Technology Co.,Ltd.The inside of this module has integrated CANopen slave station protocol stack code, which does not require the user to do secondary development. The protocol stack follows the CANopen protocol description document such as DS301, DS302, DS303 and DS305 of standard.By default, the CANopen slave station enables use a predefined connection and supports parameter storage.

The GCAN-305 is suitable for any systems with serial port communication capability. By carrying the module, the user's serial port communication devices can have CANopen communication capability  with the fastest speed and seize the market first. Users only need to use a simple serial port communication protocol can be achieved with the GCAN-305 communication, complete the module configuration and data exchange with the CANopen bus. Our company provides users with serial port communication protocol standard C files.

Module can support up to 12 RPDO and 12 TPDO of process data transmission, suitable for a variety of strong interference, high real-time requirements of the occasion, extremely small size, high-speed and real-time processing capacity and flexible and diverse applications. Making the GCAN-305 module very easy to embed into the user device, Let your device have powerful field bus function instantly.Our company can provide users with personalized customization services. Users can provide separately EDS files and firmware customization of products to help your product long-term update CANopen features to meet your customer needs.

GCAN-305 provides one CAN interface which can connetct with the CANopen network. In addition, GCAN-305 provides two UART interfaces - a communication UART interface (communication baud rate of 1200 ~ 115200bps), a debug UART interface (fixed baud rate of 115200bps).

Our company can also provide development board with GCAN-305. Users can use this development evaluation board to test GCAN-305 basic functions and pre-integration debugging. Users can use the serial port of the development evaluation board to connect GCAN-305,that use dial the code switch predefined module of baud rate and Node ID (the same as the actual usage). Development board use connection CAN bus terminal wiring way. All of above functions are readily available.
