After unpacking my Humax 9200T PVR and plugging it in the next geek thing to do is update the firmware. Humax supply a firmware update which is downloadable from their website. Alternatively it’s possible to receive the update OTA (over the air), but they don’t send those particularly regularly from what I can tell.
The firmware file is supplied with a couple of applications which can be run on a Windows PC to send it to the player. The player has a serial port on the back, so a null modem cable is required. I got a null modem cable and have an old laptop PC which has a serial port. My computers don’t run Windows though, so I thought I’d try using the Humax Windows firmware updating tools with WINE.
