3. התקנה

3.1 חיבור חומרה

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 התקנת דרייבר

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 עדכון קושחה

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

1. הגדר את Boot Switch אל ה ON מַצָב.
2. Connect the adapter to your computer via USB.
3. Your computer's Device Manager should show an 'STM Device in DFU Mode'.
4. Use a compatible flashing tool (e.g., STM32CubeProg or the web-based updater at canable.io/updater/canable1.html) to flash the desired firmware (e.g., slcan with FD support).
5. After flashing, disconnect the device, set the Boot Switch חזרה ל כבוי, ולהתחבר מחדש.

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.

4.2 CAN Bus Communication

The adapter facilitates communication between your computer and a CAN bus network. Data sent from your computer can be accepted by specific CAN nodes, while other nodes may ignore it based on their configuration. Similarly, data from CAN nodes can be received and processed by your computer.

6. תחזוקה

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

• שמרו על ניקיון המכשיר, ללא אבק ולכלוך. השתמשו במטלית רכה ויבשה לניקוי.
• הימנע מחשיפת המכשיר לטמפרטורות קיצוניות, לחות או לאור שמש ישיר.
• 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 webהאתר כדי ליהנות משיפורי ביצועים ותכונות חדשות.

7. פתרון תקלות

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

• התקן לא מזוהה:
  • Ensure the USB cable is securely connected to both the adapter and your computer.
  • נסה להתחבר ליציאת USB אחרת במחשב שלך.
  • 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.
• בעיות עדכון קושחה:
  • 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.
  • אם משתמשים ב- a web-based updater, ensure your browser and internet connection are stable.
