I know it's been asked before, but this time I'm seriously looking. I wanna make an IRDA device to connect to my motherboard's header. With the USB devices costing around £20 at the cheapest from eBay, I think this way should be cheaper. There's 4 pins; +5v, 0v, IRTX and IRRX. So we have power, plus send and receive. Surely it can't be as simple as connecting up a 3-pin receiver (as used in serial receivers) and an IR LED could it? One thing is that the IR receiving modules generally available have built in decoders which the mb may do itself, I don't know. I'm assuming though, that you can buy ones with no decoding circuitry inside? If anyone has ANY info then it's welcome here!
Found this circuit: The pins 1 to 8 are on the Hewlett Packard HSDL-1001 module. C1: 4.7 uF C2: 100 nF C3: 220 nF C4: 470 nF R1: 10 ohm R2: 330 ohm Here's the guy's site who made this: http://www.daniel-hertrich.de/ir_dev/picirdev.html. This datasheet however, would tend to imply that the circuit is connected slightly wrong. Pins 2 and 7 seem a little mixed up. So, does anyone know where in the UK to get this module or a compatible model? Just for reference, I want this for my (soon to be received, Monday hopefully) Palm III (I know they're old, but hey) and Nokia 6510 since it's easier and with a bit of luck cheaper than a data cable. Plus this would allow no cables to be needed to connect PC->Palm, PC->Nokia or Palm->Nokia which would save a lot of clutter!
This one uses the TFDS 4500, RS sell it (code 286-1380, £2.73) http://www.infrarotport.de/tfds_plan.GIF RS also do your Agilent one, IR, link, datacomms, HSDL-1001-101, RS Stock No. 240-6977, Manufacturer AGILENT TECHNOLOGIES I'd be interested in using the IRDA header rather than a serial port for general remote control, not file transfer, so any info welcome.
Oooooooh!!! Very cool, thanks One little question now; do you have an RS code for connectors for motherboard headers? My IRDA header is arranged like this: O OO OO But the single pin at the top is the NC, so I only really need a 2x2 block, or 2 2x1's.
I take it you have an ECS motherboard Get the header from Mappers and they sell the pins individually. Buy a 3x3 header and that will work fine. The circuit cpemma suggests is similar to the one I make but I use some extra caps to make sure the supply is stable. It's more like this one (don't need JP1). Meblin
Cool, thx Meblin. I actually have an MSI board; the KT3 Ultra. When you say it's nearly the same as the unit you make, do you mean make and sell (eg Meblin's Mods)? You know I've got one of your serial receivers, just wondering if you make IrDA devices now too.
Yep I do make and sell the motherboard header IrDA devices too but have not put a like to buy them on my site 'coz they were not very popular when I first started. The sensor is quite pricey compared to the Serial connector so I don't like to have too many lying around. I sell them for £9 inc P&P Meblin
Hmm, I might be emailing you soon about getting me one of them Meblin Speak to you on MSN probably in fact.
Hi guys, ok I've looked at the site relating to the IR MoBo header and it looks easy enough to build. My only question is how I get my PC to recognise it. I'm building this purely to communicate with my new 7210 (phonebook entries mainly) but am unsure how XP will handle it. After I enable it in BIOS I'll obviously need to install a driver - but which one and where can it be found? I've never used any infrared devices with a desktop before so I'm in new territory here, just unwilling to spend £20 - £40 on a tranciever! Any advice / help / links greatly appreciated
The driver should install from your OS disk (win 2k/9x/etc...) Yout phone will be able to make a direct link to the puter but you'll need some software to transfer useful stuff like your phone numbers, logos, tones, etc.... Nokia have some software that you can get from their site to download/upload your address book. It cannot transfer logos and tones. You need something like Logo Manager. Meblin PS look at my site under Infrared and click on IrDA. I have a new page on creating a PCB version.
Excelent, exactly what I was after Thanks for that. I have all the Nokia software I'll need (got it before the phone I was so keen!) It should be really straightfoward, I was just overcomplicating it in my head. Ill let you know how I get on, thanks for the link again
