1. Background

NS 1886 COFDM bidirectional transceiver natively supports50 मेगाहर्ट्ज – 6000 मेगाहर्ट्ज. तथापि, older menu boards ship with firmware capped at2500 मेगाहर्ट्ज (2.5 गीगा), 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 मेगाहर्ट्ज)
    • Cannot select 3000 MHz or higher

3. Upgrade Requirements

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

4. Hardware Connection

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

Serial AdapterMenu Board
GND (ज़मीन)GND (ज़मीन)
टेक्सास (संचारित) RX (प्राप्त करें)
RX (प्राप्त करें)टेक्सास (संचारित)

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

5. Firmware Upgrade Procedure

  1. Launch STC ISP आपके कंप्यूटर पर
  2. Configure Settings:
    • MCU Model: चुनना STC11F32XE
    • COM Port: Choose your adapter’s port (जैसे, COM3)
      💡 Tip: Verify port in Device Manager
  3. Load Files:
    • Program File: खुला RX_Pad.hex
    • EEPROM File: खुला eeprom.bin
  4. Initiate Programming:
    • क्लिक करें “Download/Program” (या “Re-program”)
    • Immediately power on the menu board
    • Observe progress bar → “Operation Completed” (10-30 सेकंड)
  5. Disconnect power after successful flash

6. Post-Upgrade Verification

  1. Reboot the menu board
  2. Access frequency settings:
    • Successful upgrade indicators:
      • मान “3” (3000 मेगाहर्ट्ज), “4” (4000 मेगाहर्ट्ज), “5” (5000 मेगाहर्ट्ज) चयन
      • Maximum value “5999” (5999 मेगाहर्ट्ज) confirmed
  3. Compare to pre-upgrade state (अधिकतम “2” विन्यास योग्य आरएफ आउटपुट पावर 2000 मेगाहर्ट्ज)

✅Success Criteria: Frequency adjustment range extends beyond 2500 मेगाहर्ट्ज से 5990 मेगाहर्ट्ज.

7. समस्या निवारण

Issueसमाधान
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 “डाउनलोड”
2. Replace serial adapter
Still capped at 2500 मेगाहर्ट्ज1. Reflash using correctRX_Pad.hex
2. Confirm MCU model STC11F32XE

Revision Notes:

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

Support Contact:
For unresolved issues, उपलब्ध करवाना:

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

⚠️चेतावनी: 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.
तथापि, the Menu configuration tool board has not updated its firmware in time and only supports 2500Mhz, 2.5गीगा.
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.
कैसे उन्नत करने के लिए?
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
खुला.
Select EEPROM file
choose eeprom.bin
Click Open, and select this one.
Re-program
After selecting here,
पावर ऑन.
Power on and look here.
the upgrade will start.
ठीक है, it will stop after the upgrade.
अपग्रेड के बाद, 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. देखने के लिए धन्यवाद.
