I realized the other day that i had the guts of one and a half Toshiba
Satellite 400cdt notebooks lying around, built one working notebook, got that up
and running, and noticed that in the leftover flotsam i had a toshiba irda
Small board, marked KS-192 and FV2IR2 and P0101 and 536073651.0.14A -- not that
i expect anyone to recognize those numbers. Has a 4 pin connector and cable,
appears to have power supply components on the board.
I desoldered the shield finally, hoping to learn what exactly this module is,
because I'd like to fill the irda header on the motherboard of my freevo system
with something that can be used to receive signals with lirc.
The module itself is simply marked "HP 1000" and has date code 9526.
I'm at a loss. I tried google, and all I found was a pdf of a magazine article
about how to add irda capability to an 8051-based device using a max3100 chip,
"If necessary, the maximum 115 kbaud is easily attainable with high-quality
optical components such as the HP-1000 IrDA module."
But doesn't really go into detail, instead providing a schematic for how to
implement 2400bps irda with an led and detector.
It's an 8 pin module, 14mm in length, which looks like it was originally
packaged as a DIP but had all the pins on one side cut off. I can post pictures,
when i get around to taking them.
The fact that the magazine article referred to it so nonchalantly gives me some
hope that it was a common part or uses a common interface.
Anybody here recognize it? or have some advice on what i should do to simply
reverse-engineer the 4 pin interface on the board - I mean, I'm guessing it's
vcc, gnd, tx, and rx - in some order - but what order, and how do i figure out
