3.1 Тоног төхөөрөмжийн холболт

Connect the SH-C31G adapter to your computer using the provided USB-A to USB-B cable. Ensure the CAN-H and CAN-L terminals are correctly wired to your CAN bus network. The device features a Boot Switch and an R120 Switch for configuration.

• Boot Switch: Used for entering DFU (Device Firmware Update) mode. Set to OFF for normal operation (Work Mode) and ON for firmware updates.
• R120 Switch: Engages or disengages the 120 Ohm termination resistor for the CAN bus.

3.2 Драйвер суурилуулах

For Windows operating systems, the device typically uses standard USB drivers. In Work Mode (Boot Switch OFF), it should be recognized as a 'candleLight USB to CAN adapter' or similar in Device Manager. For DFU Mode, it will appear as an 'STM Device in DFU Mode'. No specific driver installation is usually required for basic operation with compatible software like Cangaroo.

3.3 Програм хангамжийн шинэчлэлт

The SH-C31G supports firmware updates. This process is typically performed to enable full CAN FD functionality or to update to the latest features.

4.1 Using with Cangaroo (Windows)

The SH-C31G adapter is compatible with Cangaroo software for Windows, allowing you to monitor and interact with CAN bus networks.

1. Ensure the adapter is in Work Mode (Boot Switch OFF) and connected to your PC.
2. Launch the Cangaroo software.
3. Navigate to the 'Measurement' menu and select 'Start Measurement' (or press F5).
4. In the 'Measurement Setup' window, select the appropriate driver (e.g., 'candleLight') and verify the interface details.
5. Configure the CAN bitrate and other settings as required for your CAN network.

The DSD TECH SH-C31G adapter is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:

• Төхөөрөмжийг цэвэр, тоос шороо, хог хаягдлаас хол байлга. Цэвэрлэхийн тулд зөөлөн, хуурай даавуу ашиглана уу.
• Төхөөрөмжийг хэт өндөр температур, чийгшил, нарны шууд тусгалд оруулахаас зайлсхий.
• Ensure all cable connections are secure to prevent intermittent communication issues.
• Regularly check for and install the latest firmware updates from the official DSD TECH or Canable webгүйцэтгэлийн сайжруулалт болон шинэ функцуудаас ашиг хүртэхийн тулд сайт.

7. Алдаа засах

If you encounter issues with your DSD TECH SH-C31G adapter, consider the following troubleshooting steps:

• Төхөөрөмжийг танихгүй байна:
  • Ensure the USB cable is securely connected to both the adapter and your computer.
  • Компьютер дээрээ өөр USB порт руу холбогдож үзнэ үү.
  • Verify the Boot Switch is in the OFF position for normal operation. If it's in ON, the device will be in DFU mode.
  • Check Device Manager for any unrecognized devices or driver issues. Reinstalling drivers or updating firmware might be necessary.
• CAN Communication Errors:
  • Confirm that the CAN-H and CAN-L connections are correct and secure.
  • Ensure the CAN bus termination (R120 Switch) is correctly set for your network configuration. Typically, the R120 resistor should be ON if the adapter is at one end of the bus, and OFF if it's in the middle or not required.
  • Verify that the CAN bitrate configured in your software matches the bitrate of the CAN bus network.
  • Check for any physical damage to the adapter or cables.
• Програм хангамжийн шинэчлэлтийн асуудлууд:
  • Ensure the Boot Switch is in the ON position before connecting for a firmware update.
  • Use the recommended flashing tool and follow the instructions precisely.
  • Хэрэв ашиглаж байгаа бол a web-based updater, ensure your browser and internet connection are stable.
