USB Firmware Uploader and Instructions

This article will describe the USB firmware upgrade method for products that do not support the AVPro Edge ui with web interface updates.

You can use this along with firmware files (.fwm) found here on the knowledgebase or on https://firmware.avproedge.com.

Requirements:

- Device to be updated

- Windows PC
- USB data cable to connect the PC to the device to be updated
- Firmware FWM file

- Firmware Uploader software (see attachments at the bottom of this page)
- CH340 USB Serial Driver (direct download link here)

This example tutorial references updating an AC-SC-1X, but the process will be similar for all products.

1. If you have not already installed the CH340 USB Serial Driver: download and install the CH340 USB Serial Driver onto your PC using the link above.

2. Connect your PC directly to the USB-C POWER / CTRL port on the device using the USB data cable. 

3. Right-click on the Windows Start button and select Device Manager.

Then select the Ports (COM & LPT) drop-down menu and locate the port labeled USB-SERIAL CH340 (COMx) to confirm the device is connected to the PC.

4. Open the Firmware Uploader V1.25.

Select the correct COM, Baud: 57600, and select the Open button  to open the port.

The Status will now show as Connected in green text with COMx connect success under Messages.

5. Select the Get Version button to see the current firmware version on the device (note: screenshot below is only an example and may not display this exact version and may show other MCUs).

6. Select the file button  to load the firmware file. Make sure to select the correct firmware file for the device you are currently updating.

The firmware file will be loaded into the Open Firmware file field with the following information under Messages:

7. Select the Upgrade button to start the firmware update. The loading bar will pause at 99% for a few seconds while automatically rebooting the unit. Do not use the ForceUpgrade button. If the Uploader is not updating firmware for any reason, please contact AVPro Edge Tech Support to assist in troubleshooting your device.

8. Once the loading bar reaches 100%, use the Get Version button again to ensure the new firmware version is correct (note: screenshot below is only an example and may not display the exact version).

9. Select the Close button  to close the port, then select the X at the top to exit the Uploader. The device is now up to date on its firmware and is safe to disconnect from your PC and power.
