Correct connection must be observed as shown in the figures below:
It is necessary to navigate the red or white strip on the cable and the
cutout on the socket, which should be on one side!
If connected correctly, after on ignition, the “Status” LED on the MotronicRT
board should light up.

Connect to PC
USB-Version
MotronicRT (USB) is connected to a PC using a USB type-B cable.
MotronicRT can only be connected to a PC, i.e. There is no need to install
(connect) the emulator in the ECU, or connect a separate power source.
Connection setup
After connecting, you should have a new device in the Device manager. After
that, you need to install the USB driver.
Installing the USB driver for revisions R1.3-R4.3 (see on the device board)
Drivers can be downloaded on our website:
https://cobrartp.com/en/downloads, by selecting an item for the appropriate
version of Windows.
After downloading the driver archive, you must also select the appropriate
installer, depending on the bit depth of your operating system x86 (x32) or x64.
Drivers tested on Windoes XP, Windows 7, Windows 10. Official website of the
driver provider: https://www.silabs.com/products/development-

If there is no installer in the folder (Windows 10/11), the driver must be
installed through the Device Manager: By device (MotronicRT), right-click -
Properties - Driver - Update driver. Next, select the folder with the downloaded
drivers.
After the driver installation is successfully completed, a virtual COM port
should appear in the device manager, if there is a connected emulator:
View of the device in the device manager upon successful driver installation.
After installing the drivers, you can use the emulator with the configuration
software, and also check it in the CobraRTP Utility.
Note: COM port number may be different from the one shown above.
Installing the USB driver for R5+ revisions (see on the device board)
For revisions R5 and later, the driver is not required in the case of Windows
10/11. If you have Windows XP, Vista, 7, 8.x driver installation is required. The
driver can also be downloaded from our website:
https://cobrartp.com/en/downloads.
To install the driver, use the installer for the appropriate version of Windows:
After the driver installation is successfully completed, a virtual COM port will
appear in the device manager, if there is a connected emulator:

Bluetooth connection
To do this, your PC must have a built-in Bluetooth or a USB-BT adapter.
The range of the Bluetooth network is up to 10m (without obstacles), so you
should consider how far the PC is from the emulator. Recommended distance
up to 3m.
To connect, power must be supplied before pairing with a PC. To do this, the
emulator must be connected to the ECU with power supply.
Attention! When working via BT, the emulator must not be connected
via USB, otherwise a conflict is possible!
Connection setup
After you have made sure that the emulator is turned on (Red (BT) indicators
should be blink) and the emulator is in a stable range, you can proceed to
configure the first connection of the emulator via Bluetooth.
Connection settings will be made using the example of Windows 7 (similarly
also in Win XP, Win 8, Win 10).
1. Find the Bluetooth icon in the taskbar, click and add a new Bluetooth
device.
2. Select the device found (initially it can be displayed as unknown):

3: Select pair with password
4. Enter password - 1234:

5. Successfully complete the connection setup:
After that, 2 COM ports should appear in the device manager.
It is worth paying attention to the fact that the system defines 2 virtual COM
ports. To work with the emulator, only the “Outgoing” COM port number is always
necessary. In TunerPRO and CobraRTP Utility, the required COM port is
automatically selected.
Note:
1. Before connecting the device in the software, make sure that the
device and the PC are ready to connect, i.e. power is supplied to the
device (ignition is on) and it is in range.
2. After each power loss (ignition off) for the BT version, it is necessary
to reconnect in the program (it is not necessary to turn off and on
the bluetooth in the PC). For TunerPRO RT, just press the connect
button again:

Connection check
To test the functionality of all MotronicRT variants, you can use the CobraRTP
Utility.
You can download the latest version on our website in the "Downloads"
section.
The number of the required COM port will be selected automatically and
displayed in the status bar of the program:
1. – emulator software version.
2. – number of the active (used) COM port.
Attention! If the emulator is not recognized in TunerPRO RT, CobraRTP
Utility or other software, check if the emulator is currently connected in
another program! The emulator port can only be connected in one program
at a time, so before connecting, make sure that the device is not currently
connected in another program (process).
