If you have macOS Catalina 10.15.5 or newer, the Mac drivers are not needed.

(DO NOT connect cable to your computer yet. Only do this when you're instructed below.)

The driver for the TK503/TK504 programming cables are installed in two steps:. Pre-installation of the drivers on your PC using the programTK503TK504Installer.exe. Installation of the new hardware in Windows after the TK503 programming cable or TK504 programming cable is plugged in for the first time. Pre-installation routine 1. The TYT cable is a 'dumb' cable with no FTDI chip (it's built into the MD380). There was a warning somewhere some months back about trying to use a Baofeng-style FTDI cable with the Tytera; it doesn't work, and may damage the radio. Otherwise I'd recommend (as you have noted) plugging into a USB port on the computer.

• Windows Vista/7/8/10: Control Panel » System » Device Manager
• Windows XP: Control Panel » System » 'Hardware' tab » Device Manager

Expand 'Other devices' or 'Ports (COM & LPT)'. Whichever contains 'USB Serial Port'.

Next to 'USB Serial Port' — you'll see a number.

If the COM port number is between 1-4, then everything is fine. Move onto Step 3.

If the COM port number is above 4, then we'll have to change it so it's between 1-4. Here's how...

Cable should be plugged into computer.

1. Start VCDS-Lite software.
2. Click 'Options' button.
3. You will see 'Select COM Port' box. Select the 'COM Port' number as explained in Step 2.
4. Click the ‘Test’ button.
5. If everything is good, it should display 'Interface Status: Found!'.
6. You can now connect other end of cable to car. Turn on ignition. And you're ready to start diagnosing!

If test is not successful — check the following:

1. Other software or devices using USB ports or that same COM Port could be conflicting. You should uninstall the suspected software or device for troubleshooting this problem.
2. It should be noted that VAG-COM 409.1 KKL cable does not work on vehicles running on CAN-BUS System.
3. Cable must be plugged into the vehicle with ignition ON.
4. Test the cable with each COM Port from 1 to 4 in Windows Device Manager.
5. Make sure that the driver is installed and configured as explained in Step 1.

• Only Audi, Volkswagen, Skoda and Seat vehicles are supported. Other brands will only work for generic OBD-II functions.
• If VAG-COM 409.1 KKL cable doesn't connect — or if you get the error message 'Can't Synch Baud Rate' — then go to Options and set Start Baud to 9600. If 9600 doesn't work, try 4800 and 1200. Turn the vehicle's ignition OFF and back ON after each failed attempt to connect.
• If you have installed VCDS software before or from another source, uninstall all versions of VCDS software right now, and delete directory 'C:Ross-Tech'. Then install latest version of VCDS-Lite software by clicking here.
