Microphone Firmware Upgrade (OTA Method)
Preparation
Several microphones to be upgraded (with power supply)
One wireless AP (for wireless microphone upgrade use), or one network cable
One Windows 10/11 computer
One web plugin (File Server\common\webPackage\DCSResourceServer_Setup_xxx.exe)
One microphone firmware xxx.bin (stored in File Server\massProduction\Microphone\Wireless (or Wired) Main Board\OTA Upgrade Firmware\)
Operation Steps
Install the web plugin
If connecting wireless AP, it is recommended to first set computer to turn off firewall, forget previous WIFI networks, otherwise after connecting AP for a period of time, inability to access internet may cause system to automatically switch network back to original WIFI, leading to upgrade failure
Connect Windows computer to wireless AP (account/password refer to here), or connect via network cable to main unit's EXT/LAN port, i.e., ensure computer and microphone are on same network
Power on microphone, wait for microphone to connect to network (running light flashing or display network connection icon showing signal)
Open the main unit web backend at http://192.168.10.111, go to "Microphone Settings" → "Microphone OTA Upgrade", select the upgrade firmware xxx.bin, and click "Upgrade"
Before upgrade, must ensure IP displayed in upper right corner is on same subnet as microphone. When computer has multiple network cards, it is recommended to turn off other network cards, keep only one network card before connecting to AP
If the microphone's "System Version" is earlier than 250708, use the "Console_20250708" or earlier console version to upgrade the microphone firmware; otherwise use the latest version
Note: Wired and wireless microphone upgrade methods are similar and are not repeated here First click "Cancel" (to prevent previous upgrade from not stopping), then click "Confirm" to start upgrade. At this time all microphones will enter upgrade page, and microphone boom indicator will light up If wireless microphone upgrade process network interrupts or exception occurs, following error prompt will display, and microphone boom indicator will change color. At this time as long as network is normal, click "Cancel" and click "Confirm" to restart upgrade If wired microphone upgrade process network interrupts or exception occurs or exceeds 5 minutes without upgrade success, please operate as follows: Set the computer IP to 192.168.10.110, open the main unit web backend → "System O&M" → "Wired Microphone Firmware Upgrade", select the firmware, and restart the upgrade service Turn off wired microphone power, hold microphone side button, then power on microphone. At this time microphone enters OTA mode, all indicators flash rapidly continuously After microphone enters upgrade state, indicators stop rapid flashing, wait for microphone upgrade to complete If upgrade successful, microphone will automatically restart. Click the microphone display "Settings" → "System Information" → view "System Version" on the system information page to check whether it has been updated to the latest version
If there are many microphones, the following methods are recommended for batch viewing:
- Open the main unit web backend → "Microphone Settings" → "Switch to Information Page" (recommended for a moderate number of microphones, can be viewed one by one);
- Open the main unit web backend → "Microphone Settings" → "Scan", and observe the microphone version in the scan results (the main unit must be online; suitable for a large number of microphones that cannot be viewed one by one);
Microphone Display Firmware Upgrade (OTA Method)
Preparation
Previous version display firmware (assumed to be private_20250620)
Latest version display firmware (stored in File Server\Production Materials\Customization\Display Firmware\Microphone_xxx\private)
One genLcdFirmwareDiff.sh script
One mobaxterm software
Others same as "Microphone Firmware Upgrade" chapter
Operation Steps (Recommended for Manufacturer Service Personnel)
Open microphone display, photograph "Settings" → "System Information" page to manufacturer service personnel for confirmation
Please confirm whether display specifications of microphones to be batch upgraded are consistent (brand, model, size, etc.). If inconsistent, consult service before operating
Open computer, place private_20250620, private_20251028 in same directory as genLcdFirmwareDiff.sh script
Open mobaxterm, create new terminal
Enter the following commands (assuming the genLcdFirmwareDiff.sh script is in D:\dcs):
$ cd /drives/d/dcs/
$ ./genLcdFirmwareDiff.sh ./private_20250620 ./private_20251028
After running, upgrade folder private_private_20250620_20251028 will be generated in current directory
Following same as most steps in front of Microphone Firmware Upgrade
Computer should preferably forget previous WIFI networks, otherwise after connecting AP for a period of time, inability to access internet may cause network switch back to original WIFI, leading to upgrade failure
Open the main unit web backend at http://192.168.10.111, go to "Microphone Settings" → "Interface OTA Upgrade", click the "Upload Upgrade File" dialog, and select private_20250620_20251028 from the steps above
