The GCAN-305 is an embedded CANopen(Slave) to UART communication conversion
module .It is 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.

Module can support up to 12 RPDO and 12 TPDO of process data transmission, suitable for
a variety of the occasion. It has extremely small size, high-speed and real-time processing
capacity and flexible and diverse applications. Our company can provide users with
personalized customization services. We can provide customized EDS files and firmware to
help customer's product long-term update CANopen features to meet customer needs.

GCAN-305 provides one CAN interface which can connect 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. Development board use terminal blocks to connect with CAN bus.

Typical application                                                                                

GCAN-305 module is stable and reliable, through rigorous practice to verify. It has been widely
used in high-speed railway, subway, medical, wind power, frequency converter, elevator control
and other occasions.

Use CANopen device designed with GCAN-305 in the network is shown in the following figure.
The control of each CANopen slave station can be realized easily through the CANopen master
station device.
