4.1 Boot Switch and R120 Termination Switch

The SH-C30L adapter features two important switches:

• Boot Switch (Programming Switch): This switch controls the device's operating mode.
• ӨЧҮРҮҮ абалы: Normal Work Mode. The adapter operates with its currently loaded firmware (e.g., Candlelight).
• ON позициясы: DFU (Device Firmware Upgrade) Mode. This mode is used for flashing new firmware onto the device.
• R120 Switch (Termination Resistor Switch): This switch enables or disables the built-in 120Ω CAN bus termination resistor.
• ON позициясы: Activates the 120Ω termination resistor. This is typically required at the ends of a CAN bus network to prevent signal reflections.
• ӨЧҮРҮҮ абалы: Deactivates the 120Ω termination resistor. Use this if the adapter is not at the end of the bus or if termination is provided externally.

4.2 Using with Cangaroo (Windows)

The SH-C30L adapter, preloaded with Candlelight firmware, integrates seamlessly with Cangaroo software on Windows. Follow these general steps:

1. Ensure the Boot Switch is in the OFF (Work Mode) position.
2. Connect the SH-C30L to your computer and the CAN bus.
3. Launch the Cangaroo software.
4. Navigate to the 'Measurement' menu and select 'Start Measurement'.
5. In the 'Measurement Setup' window, select 'candleLight' as the driver and configure other parameters as needed for your CAN network.
6. Click 'Start' to begin monitoring CAN bus traffic.

4.3 Firmware Flashing (DFU Mode)

To update or change the firmware on your SH-C30L adapter, use the DFU Mode:

1. Disconnect the SH-C30L from your computer.
2. Set the Boot Switch to the ON (DFU Mode) position.
3. Connect the SH-C30L to your computer via USB. Your computer should recognize it as an 'STM Device in DFU Mode'.
4. Open a compatible firmware flashing tool or visit the online updater at canable.io/updater/canable1.html.
5. Select the desired firmware (e.g., different versions of Candlelight, SLCAN) and follow the on-screen instructions to flash the firmware.
6. Once flashing is complete, disconnect the adapter, set the Boot Switch back to the OFF position, and reconnect it for normal operation.

6. Техникалык тейлөө

To ensure the longevity and reliable operation of your DSD TECH SH-C30L adapter, follow these maintenance guidelines:

• Сактагыч: Адаптерди салкын, кургак жерде күндүн тике тийген нурунан жана экстремалдык температурадан алыс сактаңыз.
• Тазалоо: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners or solvents, which can damage the electronics.
• Колдонуу: Handle the adapter with care. Avoid dropping it or subjecting it to strong impacts. Do not pull on the cable to disconnect the device.
• Байланыштары: Ensure all connections are secure but do not overtighten terminal block screws. Regularly inspect cables for any signs of wear or damage.

7. Кыйынчылыктарды

If you encounter issues with your SH-C30L adapter, consider the following troubleshooting steps:

• Түзмөк таанылган жок:
• Ensure the USB cable is securely connected to both the adapter and your computer.
• Verify that the necessary drivers are installed for your operating system. Refer to the DSD TECH webдрайверлерди жүктөө үчүн сайт.
• Check the Boot Switch position. If it's in DFU Mode, the device will appear differently in Device Manager. Switch it to OFF for normal operation.
• No CAN Bus Communication:
• Confirm that the CAN_H, CAN_L, and GND connections to your CAN bus are correct and secure.
• Check the R120 Termination Switch. Ensure it is set appropriately for your network topology (ON if the adapter is at the end of the bus, OFF otherwise).
• Verify that your software (e.g., Cangaroo) is correctly configured to use the adapter and the correct CAN bus parameters (baud rate, etc.).
• Ensure the CAN bus itself is active and functioning.
• Микропрограмманы жаңыртуу маселелери:
• Make sure the Boot Switch is in the ON (DFU Mode) position before attempting to flash firmware.
• Use the recommended flashing tool or online updater from canable.io.
• Ensure a stable USB connection during the entire flashing process.
