4.5 Good product, price and delivery. Wobbit | 09/09/2009 | See all Wobbit's reviews (12) I bought this to update the firmware of a DigiFusion FVRT145 freeview recorder via it's serial port using my Mac.On the downside this adapter feels cheaply made, a bit hollow and plastic but at just under a fiver it's reletively inexpensive and it works as it should which is very good. There's drivers included on the supplied mini-CD but they didn't work as both the Mac drivers were corrupt and wouldn't expand/decompress. However, alternatives were easily sourced from the web so it's no big deal.When used with a Null Modem Cable I managed to successfully update the DigiFusion firmware using my Mac (G4 iMac USB1 connection). The only hassles I had were realising I needed configuring the Mac's network settings for the device and correctly setting up a terminal app called ZTerm.For this job alone this adapter has done the business, so very happy for the minimal investment.
