Hello.
I'm planning on upgrading the firmware on My Humax 5400 to the latest version.
Can I use the serial cable that came with my modem, or do I need a different type of cable to connect my PC to the Humax?
If you used it for a modem or similar then it is probably the wrong type. Go to any PC store (no PC World, very expensive and they don't know what they're talking about) or Maplin and ask for a Nulmodem cable.
