Questions on working with controllers over the web interface

How to start working with the controller over the USB?


CCU Proxy program connects your PC to the controller. To work with the controller over the USB you need:

  1. Download the ccuproxy.zip file at ccuproxy.zip and extract its contents into a separate folder.
  2. Connect the controller to the USB port of the computer. If the Internet access is available, the required driver will be installed automatically. If the driver is not automatically installed, you need to install it manually specifying the CCU_USB_driver.inf file in the folder with the extracted ccuproxy.zip. After the driver is successfully installed, the USB LED will turn orange.
  3. Start the CCU Proxy program with the ccu_shell.bat file. If there is the request to allow to make changes to your device upon starting program, you must accept it. CCU Proxy has no graphical user interface and looks like black window with text. Never close this window while you are working with the controller over the USB. Run "ccuproxy.exe -h" at the Windows Command Prompt to see all CCU Proxy startup options.

    Run the bat files from the standard Windows File Explorer only!

  4. After starting the CCU Proxy with ccu_shell.bat, a browser window will open prompting to enter the username and the password. After specifying the username and the password you log in to the CCU Shell to configure the controller.

    When starting CCU Proxy with ccu_shell.bat, the default Windows browser is used. If the default browser is not from the list of compatible, specify a compatible browser as the default Windows browser, and restart CCU Proxy.

    To avoid unauthorized access it is not recommended saving the username and the password in a browser on a shared computer.

  5. After completing the work in the CCU Shell, you must click “Log out” at the top right corner and close the browser.
  6. Close the CCU Proxy program.

How to manually configure the controller using the USB to work over the Internet?


  1. Log in to the CCU Shell over the USB connection.
  2. Open the "Common connections parameters" page.
  3. Set max session duration in the "Internet" group. Click "Submit". If the value is "always online", the controller will immediately start connecting to the Internet.
  4. Open the "Connections" page and select desired connection.
  5. Set the username and password. Check the "Admin rights" checkbox!
  6. Set your own phone number.
  7. In the "Incoming call reaction" group in the drop-down list select the required item. For example, if control with voice assistant is not required, select "Reject call (DTMF not available)". Check the "Connect to the Internet using https://ccu.su" checkbox.
  8. Click "Submit".
  9. Take note of the username and the IMEI code displayed at the top right corner of the CCU Shell as admin@012345678901234, which will be required later to log in to the CCU Shell over the Internet.

How to automatically configure the controller without the USB to work over the Internet?


Auto-linking allows you to start working with the controller over the Internet without using the USB connection at all and done only with the factory configuration. To auto-linking:

  1. Insert the SIM card in the controller and connect the power. The PIN code protection on the controller's SIM card must be disabled. Internet and caller ID must be enabled on the controller's SIM card plan.
  2. Call the controller’s SIM card number from your own phone. The caller’s phone number will be saved into the first connection. After that, the controller will be connected to the Internet for 30 minutes. If required, you can reconnect the controller to the Internet by calling from the previously linked phone number.
  3. Take note of the IMEI code printed on the label at the bottom of the controller, which will be required later to log in to the CCU Shell over the Internet.

How to bring the controller online?


If the controller is not configured to be always online, bring the controller online in one of the ways:

  • by a phone call to the controller from the previously saved phone number;
  • by sending to the controller the "/pass online !" SMS message.

How to log in to the CCU Shell over the Internet?


  1. If the controller is not configured to be always online, bring the controller online in one of the methods described above.
  2. Start the browser and open https://ccu.su. Then you will be prompted to enter your username and password.
  3. In the "Username" field, enter the username and the IMEI in the format: user@IMEI, where user is the username specified in the connection settings, and IMEI is the 15-digit IMEI code of your controller. For example: admin@012345678901234. In the "Password" field, enter previously set password.

    To avoid unauthorized access it is not recommended saving the username and the password in a browser on a shared computer.

  4. After completing the work in the CCU Shell, you must click "Log out" at the top right corner and close the browser.

What to do if the username or password for login the controller is lost?


In case of losing the username or password, you need to reset the controller to the factory settings. Connect the controller to the USB port of the computer and run reset.bat in the ccuproxy folder. After 30 minutes, all the controller settings will be reset, and the default username and password will be set: admin and password.

How to run CCU Proxy program under Linux and macOS?


After downloading ccuproxy, it is required to set the execute file attribute. For example, this can be done in the terminal using the command:

chmod +x ccuproxy

All ccuproxy running options can be viewed using the command:

./ccuproxy -h

In most cases, for local use it is enough to run without parameters:

./ccuproxy

After which the controller will be available at http://localhost:8080.

What are the features of running CCU Proxy under Linux on the Raspberry Pi platform?


To increase the stability of working over the USB in the Raspberry Pi, add dwc_otg.speed=1 to /boot/cmdline.txt. Then restart the Raspberry Pi.
