用法上，该设备为工业级CAN转光纤转换器，安装便捷，采用导轨式固定即可。接线时，CAN总线端接入CAN_H、CAN_L、EARTH端子，光纤端根据需求选择SC/ST/FC接口，搭配单模/多模、单芯/双芯光纤。通过拨码开关可灵活配置CAN波特率（5Kbps~1Mbps），并选择是否启用120Ω终端电阻，成对使用即可实现CAN与光纤信号透明无损互转，无需复杂调试，微秒级转换时延保障通信实时性。其中GCAN-208-1可同时延长两条CAN总线，GCAN-208-2支持光纤级联，适配不同组网需求。
In terms of usage, this device is an industrial grade CAN to fiber optic converter, which is easy to install and can be fixed with a guide rail. When wiring, the CAN bus end is connected to CAN-H, CAN_L, and EARTH terminals, and the fiber end is equipped with SC/ST/FC interfaces according to requirements, paired with single-mode/multi-mode, single core/dual core fibers. By using a dip switch, the CAN baud rate (5Kbps~1Mbps) can be flexibly configured, and whether to enable a 120 Ω terminal resistor can be selected. Paired use can achieve transparent and lossless conversion between CAN and fiber optic signals, without the need for complex debugging. The microsecond level conversion delay ensures real-time communication. GCAN-208-1 can simultaneously extend two CAN buses, while GCAN-208-2 supports fiber optic cascading to meet different networking requirements.
