DIN rail. GCAN-208 series module PE is connected with the shell. If the cabinet or rail where the module is installed is fixed to a grounded metal component board, the module will be grounded automatically, and no external grounding wire is required. -
Page 8: Interface Definition And Function
CAN bus interfaces and one standard optical fiber interface (single-mode, multi-mode, SC, ST, single-core, dual-core optional). The power interface of the GCAN-208-1 module is led out by a 3 PIN plug-in terminal (orange). The position of the power supply and optical fiber interface and... - Page 9 Table 2.2 GCAN-208-1 fiber interface definition The CAN bus interface of GCAN-208-1 module is led out by two 3 PIN plug-in terminal blocks (green), which can be used to connect 2 CAN bus networks or devices with CAN bus interface. The interface position and interface definition are shown in Figure 2.4.

Page 12: Equipment Use
3.1.1 Configure the CAN bus baud rate through the DIP switch When the user uses the GCAN-208 module for the first time, if you already know the CAN bus baud rate, you can first open the device shell (unscrew the black screws on both sides) and directly use the DIP switch inside the device to adjust the corresponding CAN bus Baud rate. - Page 13 The specific usage method is as follows: 1. Turn all the baud rate dial switches of the GCAN-208 module to the digital side. 2. Correctly connect the GCAN-208 module to the CAN bus (ensure that the wiring is correct and the terminal resistance is correctly added).
- Page 14 Vhandy Technology GCAN-208 user manual recognized, and the recognized baud rate can be enabled when the module is powered on again. If the red light is always on after the strobe, it means that the recognition is not successful. The physical layer needs to be checked at this time.
- Page 15 The value in this file cannot be manually modified to change the baud rate of the device. 2. GCAN-208-1 has two independent CAN buses. During automatic identification, it will start with CAN1 first, and then CAN2 will be identified after CAN1 has been identified.

Page 16: Connect With Optical Fiber
CAN bus wiring terminals. 3.2 Connect with optical fiber The optical fiber interface type of GCAN-208 series module can choose SC and ST interface, and the transmission mode can choose single-mode and multi-mode. In actual use, users only need to select the corresponding optical fiber cable to plug and play. -
Page 17: Connect With Can Bus
Single-core optical fiber connection requires pairing of A and B devices. 3.3 Connect with CAN bus GCAN-208 series modules are connected to CAN bus by connecting CAN_H to CAN_H and CAN_L to CAN_L to establish communication. The CAN bus network adopts a linear topology, and the two farthest terminals of the bus need to be installed with 120Ω... -
