HP49G+ I/R-Problems Message #1 Posted by Andre Koppel on 13 Aug 2004, 12:25 p.m. I am a long time user of a HP48GX. Today I have received a brand new HP49G+. Playing around with the beast I was absolutely unable to transfer anything via I/R. I have defined the flags to use I/R transfer. No way to transfer data to/from the HP49G+ to the HP48GX. The same problem while trying to print from the HP49G+ to a HP 82240B (I/R-Printer). The HP49 shows the printing symbo, but nothing happens on the printer (it works well with the HP48). Any ideas?

Re: HP49G+ I/R-Problems Message #2 Posted by James M. Prange on 13 Aug 2004, 3:09 p.m., in response to message #1 by Andre Koppel The 49g+'s IrDA doesn't work with the "old" 48 series "Serial IR". To transfer between them, you'll have to use your computer as a go-between. You should be able to print to the 82240B as long as flag -34 is clear (Print via IR), but the range has been drastically reduced. About the best I've been able to get from my 49g+ is 3 inches. Try it really close to the printer's IR window. Regards, James

Re: HP49G+ I/R-Problems Message #5 Posted by Tim Wessman on 1 Sept 2004, 10:52 a.m., in response to message #4 by mouezapeter It is IrDA. So it won't connect with older hp calculators. It will however, connect with any IrDA enabled device such as a cell phone. The sending range is only effective up to 3-4 cm away though.
