USB support for the 48GX?
Message #1 Posted by Matt Agajanian on 25 May 2012, 11:00 p.m.

Hi all,

I'd like to add the 48GX back into my collection. Although I've got the 50G which, although drops support for the 48 expansion cards, the 50G adds and a whole bunch more on top of the 48GX. But, would there be cabling and software support for USB and Macintosh running either OS 9.2.2 or OS/X (10.4.11)? That way, I could use a 48GX with data storage and archival capabilities?

I've used USB-serial adapters with the 48SX and 48GX without any trouble. I had best results with the adapters using the FTDI chipset, and certain models of Keyspan, and mixed results with the Prolific chipset.

I just used an ordinary terminal program. I'm not aware of any special software for MacOS.

Thanks for the Keyspan remind. I forgot about them.

Hi,

there exist several simple solutions for connecting an HP-48GX to a PC through USB using a serial-2-USB converter.
I use a Sitecom CN-116 with a normal HP serial cable, and the custom made USB cable from teknovo also works well.

These days, you can even hook up an HP-41 to a PC via USB using a PIL Box, thanks to J.F. Garnier and Christoph Giesselink:-)

I purchased an HP-48G to PC USB interface cable that works fine. I believe that I purchased it on eBay. eBay is currently showing a similar cable, although mine does not have LED indicators. Search eBay for what you want.

I run the HP Connectivity kit on my iMac in a Parallels partition for Windows 7.
