Re: HP 48 cannot communicate with HP 49/50 via IR Message #12 Posted by Michael de Estrada on 2 Mar 2009, 11:21 a.m., in response to message #11 by Tim Wessman
Now you're talking! This is what I really wanted to do in the first place. The price of this cable is about the same as one of those USB to RS232 serial adapters with the fancy Prolific chipset. I already have the RS232 serial cable for my HP 48SX, so I'm set, and there's no need to load new software on my computer. This reduces the 2-step procedure (HP48SX to PC to HP50g) down to a 1-step direct procedure (HP48SX to HP50g).
After checking out the hpcalc.org site, I learned something else about my HP 50g. I can save the batteries, by powering it from the PC with the USB cable. Apparently, the HP 50g has the smarts to do this, similar to other USB devices like my mpeg player.
Thanks for the help!
Michael
