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.

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.

Download and save both below to your PC/Laptop.
