Upgrade PVR800 HD Tool ~ Using a null modem cable
Connecting up
If you are using a PC with a dedicated RS232 serial ports, the port reference will usually be COM1 or COM2 depending on which port you connect to.
If you are using an USB to RS232 serial converter cable with the null modem cable, check that you have the correct COM port selected when you start the process.
Sometimes you need to reflash the USB/RS232 software on your PC to activate the com port. The software on the USB/RS232 converter usually selects COM3 or COM4. If you have the wrong port setting you will get a “can’t find port” error,
although, you don’t always get a port error every time you select the wrong port.
