1.1功能概述 
1.1 Function Overview 

GCAN-226-N模块模块作为一款高性能CAN总线环网控制器，集成了2路CAN接口。在构建CAN总线网络时，运用GCAN-226-N模块将CAN总线的首尾相连，能够组成环网拓扑结构。该环网具备显著的冗余特性，当线缆在任意位置发生断开情况时，凭借其内部独特的通信机制与冗余设计，总线通信功能不会中断，仍可维持正常的数据传输。 
The GCAN-226-N module, as a high-performance CAN bus ring network controller, integrates 2 CAN interfaces. When building a CAN bus network, using the GCAN-226-N module to connect the ends of the CAN bus can form a ring network topology structure. This ring network has significant redundancy characteristics. When the cable is disconnected at any position, with its unique communication mechanism and redundancy design, the bus communication function will not be interrupted and normal data transmission can still be maintained. 

GCAN-226-N模块是连接不同CAN总线网络的高性能工具，同时具有体积小巧、即插即用等特点，也是便携式系统用户的最佳选择。GCAN-226-N模块集成CAN接口电气隔离保护模块，双路CAN分别隔离，使其避免由于瞬间过流/过压而对设备造成损坏，增强系统在恶劣环境中使用的可靠性；双路CAN分别集成指示灯，用以展示对应CAN总线状态。 
The GCAN-226-N module is a high-performance tool for connecting different CAN bus networks, with features such as small size and plug and play, making it the best choice for portable system users. The GCAN-226-N module integrates a CAN interface electrical isolation protection module, with dual CAN isolated separately to prevent equipment damage caused by transient overcurrent/overvoltage and enhance the reliability of the system in harsh environments; Dual channel CAN integrates indicator lights to display the corresponding CAN bus status.
