1. фон

The 1886 COFDM bidirectional transceiver natively supports50 МГц – 6000 МГц. аднак, older menu boards ship with firmware capped at2500 МГц (2.5 Ггц), displaying “2” as the maximum frequency setting (≈2000 MHz). This guide details the firmware upgrade process to unlock full 6 GHz support.

2. Pre-Upgrade Verification

  1. Power on the menu board
  2. Navigate to frequency settings
  3. Confirm limitation:
    • Maximum displayed value: “2” (2000 МГц)
    • Cannot select 3000 MHz or higher

3. Upgrade Requirements

апаратныя сродкіSoftware/Files
• 1886 Menu Board
• USB-to-RS232 Serial Adapter
• Computer		• STC ISP Programming Tool
•RX_Pad.hex (Main firmware)
•eeprom.bin (EEPROM data)

4. Апаратнае падключэнне

⚠️ Perform all connections BEFORE powering on
Connect the serial adapter to the menu board:

Serial AdapterMenu Board
GND (Зямля)GND (Зямля)
Тэхас (Перадаваць) RX (Атрымлівайце)
RX (Атрымлівайце)Тэхас (Перадаваць)

📌Critical Note: TX and RX must be cross-connected. Incorrect wiring will prevent communication.

5. Firmware Upgrade Procedure

  1. Launch STC ISP на вашым кампутары
  2. Configure Settings:
    • MCU Model: Выберыце STC11F32XE
    • COM Port: Choose your adapter’s port (напр., COM3)
      💡 Tip: Verify port in Device Manager
  3. Load Files:
    • Program File: Адкрыты RX_Pad.hex
    • EEPROM File: Адкрыты eeprom.bin
  4. Initiate Programming:
    • націсніце “Download/Program” (або “Re-program”)
    • Immediately power on the menu board
    • Observe progress bar → “Operation Completed” (10-30 сек)
  5. Disconnect power after successful flash

6. Post-Upgrade Verification

  1. Reboot the menu board
  2. Access frequency settings:
    • Successful upgrade indicators:
      • Каштоўнасці “3” (3000 МГц), “4” (4000 МГц), “5” (5000 МГц) па выбары
      • Maximum value “5999” (5999 МГц) confirmed
  3. Compare to pre-upgrade state (макс “2” максімальная магутнасць перадачы адрозніваецца 2000 МГц)

✅Success Criteria: Frequency adjustment range extends beyond 2500 да МГц 5990 МГц.

7. пошук няспраўнасцяў

IssueРашэнне
Connection failed1. Verify TX/RX cross-connection
2. Try different USB port
3. Reinstall serial drivers
Programming stalls at 0%1. Power on EXACTLY after clicking “спампаваць”
2. Replace serial adapter
Still capped at 2500 МГц1. Reflash using correctRX_Pad.hex
2. Confirm MCU model STC11F32XE

Revision Notes:

  • 2025-06-07 v1.0: Першапачатковы выпуск
  • Required files: RX_Pad.hex, eeprom.bin
  • Tool version: STC ISP v6.88+ recommended

Support Contact:
For unresolved issues, забяспечыць:

  1. Screenshot of STC ISP error log
  2. Hardware revision code (bottom of menu board)
  3. Serial adapter model

⚠️папярэджанне: Using incorrect firmware files may brick your device. Verify file compatibility before flashing.

how to upgrade firmware of 6Ghz COFDM wireless Ethernet transceiver module?

How to upgrade the 1886 menu board firmware to support 6 GHz transmission frequency.
Because our 1886 COFDM bidirectional wireless transmission transceiver supports from 50Mhz to 6000Mhz.
аднак, the Menu configuration tool board has not updated its firmware in time and only supports 2500Mhz, 2.5Ггц.
Let us first take a look at the situation before the upgrade.
Look here.
The maximum setting is 2
This means that the maximum transmission frequency is 2000Mhz plus and cannot reach 3000Mhz.
Now we will upgrade this board.
and it can reach 6000Mhz 6Ghz.
як абнавіць?
Don’t connect the power firstly.
This menu board is connecting to RS232.
USB to RS232 serial port tool
Then connect Ground to the Ground of the menu button board
Then connect TX to the RX of the menu button board
the RX of RS232 is connected to the TX of the menu button board.
After connecting like this,
Then operate on the computer
Run the tool STC ISP
Open the tool.
Select MCU type here.
MCU model.
Then find it here.
select STC11F32XE
Then select the serial port tool.
According to the actual port of your device
After selecting here,
open the code file
choose RX_Pad.hex
Адкрыты.
Select EEPROM file
choose eeprom.bin
Click Open, and select this one.
Re-program
After selecting here,
Уключэнне.
Power on and look here.
the upgrade will start.
Добра, it will stop after the upgrade.
Пасля абнаўлення, we will operate the menu configuration board to see if it supports 6Ghz.
We press the menu to verify the menu.
We could only adjust it to 2000Mhz plus before.
Now we can adjust it to three, four, five.
and the maximum can be adjusted to five hundred ninety-nine.
This means the upgrade was successful. Дзякуй за прагляд.
