Step-by-Step Instructions



Step 1 - Installing the program on a computer or tablet

Install the software from the manufacturer's website: quantexlab.com/ru/download.html
(according to the type and bit depth of the operating system).

ScanDoc for Android (minimum version 6) can be downloaded from the official Google Play store.

The ScanDoc program for iOs (minimum version 10) can be downloaded from the official App Store.

App Store

Step 2 - Getting the latest firmware for the interface

Launch the new ScanDoc software on your computer or mobile device using the desktop shortcut.

Scanner serial number input form

When you first launch the program, a form for entering serial numbers will appear. Enter your scanner's serial number.

If you have multiple scanners, enter their serial numbers separated by commas, for example: 25478, 1230.

The program will then automatically download the firmware files and the vehicle make files from the internet for your scanner.


Step 3 - Program update

Options section
  1. In the program, click the button at the top of the window, an additional side menu will appear.

    Select the communication channel you want to use to connect to the interface. The selected channel will be shown at the top of the menu.

    On a computer, three communication channels are available: WLAN, BLE and USB. On mobile devices, only WLAN and BLE are available.

Connecting via WLAN

Connecting via WLAN
  1. On your computer or smartphone, open the list of available WLAN networks and connect to your interface's network.

    The network name matches the scanner's serial number, and the password is the word scandoc followed by the serial number without the letter.

    For example, if your scanner has serial number s/n: N17008, the network will be named N17008, and the password will be scandoc17008.
    Note: This configuration is set in the device's WLAN module by default.

Connecting via BLE

Connecting via BLE 1 Connecting via BLE 2
  1. Unlike WLAN, the interface does not appear in the list of BLE devices on your computer or smartphone until the ScanDoc software itself initiates the connection. There is therefore no need to look for it in the BLE settings.
    This is done for security reasons: the interface stays permanently in the vehicle, and this approach prevents outsiders from discovering it and connecting via BLE.

    BLE pairing happens during the first connection to the device. During step 4, when updating the firmware, select the BLE connection. After a few seconds, a window will appear on the screen asking for the pairing password — the password must be entered in that window.

    The password (PIN code) is the scanner's serial number without the letter.

    For example, if your scanner has serial number s/n: N17008, the password will be 17008.
    Some devices (in particular Mac OS) require a password of exactly 6 digits. In that case, simply add a leading zero.
    For example, for the scanner s/n: N17008, enter the password as 017008 (zero + 17008).

Connecting via USB

Connecting via USB 1 Connecting via USB 2
  1. The USB connection is available only in the desktop version of the ScanDoc software. On mobile devices (Android and iOS) this communication channel is not supported — use WLAN or BLE instead.

    Connect the interface to your computer with a USB cable. The first time you plug it in, the operating system automatically detects the interface as a Virtual COM Port and installs the required drivers. On modern versions of Windows 10/11, macOS and Linux the drivers are installed automatically, no further action is needed.

    Once connected, open Device Manager and find the name of the port the interface is attached to:

    • On Windows, open Device Manager → Ports (COM & LPT) and look for an entry like COM4, COM4, etc. If multiple ports are listed, unplug and reconnect the cable — the correct port will appear last in the list.
    • On Linux, run ls /dev/ttyUSB* or dmesg | tail in the terminal right after plugging in the cable. The port name typically looks like /dev/ttyUSB0.
    • On macOS, run ls /dev/tty.usb* — the port name will look like /dev/tty.usbserial-XXXX.

    Enter the port name you found in the ScanDoc software settings, in the corresponding field of the selected device.

Options section
  1. In the program, click the button at the top of the window, an additional side menu will appear.

    Click the "Settings" button in the side menu, you will be taken to the program settings window.

Saving firmware to scanner
  1. In the options window, click the Update firmware on the interface button

    The firmware will be written to the scanner. The device is now ready for use.

    Updating via WLAN or USB takes approximately 30 seconds, while via BLE it takes about 5 minutes.

    If you're not yet familiar with the ScanDoc software, you can read the detailed user manual.


Step 4 - Get familiar with how the interface works

A few important features that are useful to know about when using the interface on a daily basis.

Single active communication channel

When powered on (connected to the OBD-II port), the interface is ready to accept connections over all available channels — WLAN, BLE and USB. As soon as the first connection is established, the other channels are automatically disabled, and the interface operates only on the selected channel until the power is cut off.

To switch to a different communication channel, unplug the interface from the OBD-II port and plug it back in.

Limited number of paired devices

The number of devices that can be paired with the interface is limited and is defined in its settings. By default, the interface remembers only one device — so even after the power is cycled, other phones and computers will no longer be able to connect.

To remove a previously paired device or to increase the maximum number of pairings:

  1. Connect to the interface via WLAN.
  2. Open the interface settings page in your browser at http://192.168.12.3.
  3. Make the necessary changes and save them.

Automatic sleep mode

If there is no communication with the program for more than 3 minutes, the interface enters sleep mode to avoid draining the vehicle's battery.

The interface wakes up automatically when the engine is started and continues to operate on the same communication channel it was using when it went to sleep.

The time after which the interface enters sleep mode can be changed on the same settings page at http://192.168.12.3.
Note: when connected via USB, the interface does not go to sleep — sleep mode applies only to the wireless communication channels (WLAN and BLE).
