Cables needed to flash your Eurov0x. If you have a PC/Laptop with a 9 pin serial socket then all you need is a Null Modem Cable, see pic below. If you have a PC/Laptop that doesn't have the 9 pin serial socket you will need a Null Modem Cable and a USB adapter, See pic below. Null Modem Com/Port setup Tutorial USB DB9 device coms/ports set up. Note: Some people experience difficulties with the USB adapter, most of the time it is purely a port assignment problem. To rectify this make sure you have downloaded your driver and follow below to assign a port: To see which port your USB adapter is connected to, connect your USB adapter and follow the following instructions: 1. Go to the Start Menu 2. Right click on "My Computer" 3. Select "Properties" 4. Click on the "Hardware" tab 5. Click on "Device Manager" 6. Click the + sign next to "Ports (COM & LPT)" 7. One of the listed ports should indicate which port your USB adapter is connected to (e.g. COM1, COM2, COM3, etc.) 8. Go back to loader, (UFL, dnupman, voxer) and make sure it is looking at the correct port. 9. You should be able to transfer data once the correct port is selected Follow my advice to step 7. Locate your USB Adapter (port *) Right click on that port and select properties. Then select port settings, then select advanced. At the bottom of that tab will be a drop down box with the port selected (port * in your case). Use the drop down to select another port (eg 1, 2 or 3). If the port you want to use is already allocated to something else, you can use the same procedure to reassign that port after you have finished. Save the selections in the usual way. The USB converter will be permanently assigned to the port you selected. This is based on Windows XP. Vista differs slightly in regards to device manager but the principle remains the same once you have a compatible device driver. And if you are still having problems with the USB adapter then its time to get a serial PCI card. If you have a PC and you are struggling with the usb adapter or you have Vista like me you could install a PCI serial card which is easily added to you PC and with this all you need is the null modem cable which gives you a direct link from your box to the pc.
