    I am looking for pinout / functionality info for the Treo connector so that I can play around with adding solar panel charging, tapping into the audio to feed to the car's audio system, constant backlight at night in the car etc. Any help in locating this info appreciated.

    You can find Handspring's Technical Reference Guide here:

    http://www.handspring.com/developers...chRef_Treo.exe

    It has the pinouts in it.

    Thanks for the link Druce! The tech manual has lot's of info that I should find interesting read to learn more about the "nuts and bolts" of the Treo. Too bad audio and backlight control is not brought out to the 15 pin connector. So, it's either through the earphone jack or inductively pickup the speaker if I want Treo audio through the car's sound system.

    I have one of those clamp-on generic phone->radio things. They sell them by the pair for < $20. Doesn't sound so good.

    Not sure if you are going to have any luck with the solar charger. I hooked up one of those hand crank hand-e-chargers and I don't believe it puts out enough current to effectively charge. Seems almost like it drains the Treo even though the charge light goes green. Weird.

    iSun should do the trick on the solar theme. I don't think they do a Treo plug but shouldn't be too difficult to sort that out.

    You can rewire the headset so it would connect to the main connector - still can't understand HS for not doing it so, not even in the T600.
    (They clearly don't think in Car-Hands-Free sets language)

    As to lighting, that's another trivial Cell phone issue, which HS forgot all about (peripheral equipment codes in HW, which allows diffrent usage modes and settings according to device used)

    Great ideas, when you make something of it, don't forget us :-)

    After PalmOne bought Handspring they shut down the handspring.com web site, and they apparently didn't bother to put a copy of the Treo TechRef onto their "plugged in" web site (at least I can't find it, and they didn't answer my email). So when I finally found a copy of the Treo TechRef I put it on my web server, here:

    http://www.burtonsys.com/handspring_treo_techref.html

    It covers the Treo 90, 180, and 270. The Treo 300 isn't mentioned, but it is similar to the 270, except that it is for Sprint CDMA/PCS instead of GSM.

    What about the 650? I can't find a pinout for that anywhere. I have a plugged in login too and it didn't get me far.

    It's in the SDK 4.0 docs.

    register and get a plugged in account

    http://developers.palmone.com/pe/Rep...ectId=10127113

    hopefully that "objectid" in the url isn't just tied to my session.

    Otherwise:
    http://pluggedin.palmone.com/regac/pluggedin/login.jsp
    and look for: palmOne_SDK_4_0_BETA_Docs_Developer_Guide.pdf
    about 6 links down from the top.

    page 134 & 135

    It says "confidential" on the top of every page so I guess no one smart is going to host a copy that's more convenient. I have doubts about even pasting the table from a page that has a confidential watermark right on the same page.

    There is no drawing right there, but the 3 side-by-side columns that number all the pins by just power, just data, and all, tells you which way the pins are numbered because you know which side the power pins are on.

    Thank You for finding this Mark!

    Hi,

    Have you successfully made the serial cable to use wired GPS with Treo 650 ? If you do, can you show me how to do it ?

    Thanks

    I finally nailed down the correct wiring as far as what pin goes to what pin, but it doesn't work. The shield is counted as a PIN, usually "off by one" errors are a software thing but I managed to do it in hardware. I had a serial line connected to the hotsync init pin and if the gps was plugged in the treo would just try to hotsync over & over no matter how much you pressed cancel. But, that experience, and looking at my usb sync cable where the digital-gnd pin sticks out further so it contacts first, really made it sure which pins are the ones I want.

    I think what I need to do now is inject a couple of optoisolators or op-amps to turn the treo's 3.3v signal into a 5v.

    You're right that the 3.3v TTL signals need to be converted to RS-232 somehow. Have you seen this from Shadowmite's site?

    strange... I always thought "ttl" meant 5v. rs232 is really 12v. The slip of paper that came with my sgr-300 claims that it can use serial from ttl up to full rs232 levels.
    I just checked and 3.3v is right in the middle of the range for ttl.
    this chart:
    http://www.twysted-pair.com/74xx.htm
    shows that the typical output-high v is 3.5 but the minimum that is still within spec is only 2.4! There should not be any problem!
    I think it won't be too hard to amp the signal to 5v though seeing as there is 5v supply handy. It's worth a try.
    I don't know what "weak pull up" means in the treo docs though. I mean I know roughly what a pull-up resister is and does, but I don't know what a weak one is or what it means in english when it comes to trying to use this serial signal.
    Gawd and I had a ham radio licence when I was 11 (back when you had to know electronics and radio and morse and pass tests on all of it) and took 2 years of electrical engineering in college. I guess electronics is not like riding a bike.

    Hi,

    I am very interested in this subject. I real all the document, but I am still some how confused, basically, I would like to know which pin (Treo 650 connector side) is

    1) TX
    2) RX
    3) ground
    4) Audio
    5) Mic

    If you have all the information for all pins will be greatly appreciated.

    It's all in the section titled "Pinout of the multi-connector" in the Developer Guide.

    1) TX = pin 10
    2) RX = pin 11
    3) ground = pin 4 and pin 18 (shield ground)
    4) Audio = pin 14 (left), pin 15 (Right)
    5) Mic = none... the microphone is not accessible via the connector.
    .

    Hi Mark

    The pin number is based on Treo 650 connector ? not the syn cable connector ?

    Thank you so much for the help. I am going to make one cable to see it works or not

    The Developer Guide lists those pin assignments under Pin # on Device/Multi-Connector.

    Don't forget you'll need some sort of TTL-RS232 converter to make it work. I've attached an old schematic I used to make a serial cable for my Visor Deluxe using a few simple components. It was powered from the serial port so I don't know if it will work for connecting standalone serial devices to the 650. On the Visor, pin 1 = RXd, pin 8 = TXd, pin 4 = GND, pin 2 = HotSync interrupt.
