The GCAN-205 is a CAN-Bus and RS485/Ethernet converter. GCAN-205 converter integrated Modbus RTU/TCP protocol. This module can convert the data between CAN-Bus and Modbus. With this converter, equipment that used Modbus protocol can connect to CAN-Bus without changing the hardware structure, this makes multi-Bus interconnection very flexible, and extends the application scope of CAN-Bus.
CAN Features ? Integrated 1 CAN-Bus interface with terminal ? CAN-Bus signals CAN_H, CAN_L, CAN_GND ? CAN-Bus supports CAN2.0A and CAN2.0B frame format, conform to ISO/DIS11898 standards ? CAN-Bus baud rates range from 5Kbps to 1Mbps ? CAN-Bus isolation converter insulation voltage DC 1500V

Working mode Trace mode When Modbus master writes corresponding address data of Modbus with a 06 instruction.If the data changes,it will trigger the corresponding data transmission of CAN. Timer mode Users can set interval time in "Send Timer",transmit CAN frame data circularly.Input the decimal number,the unit is milliseconds.For example,input "1000" can trans_x001f__x001f_mit once at intervals of 1000ms.
