I have been beating myself up over this for the longest (including doing some searches on here) and was wondering if it is possible.

When I had my old DSM, the closest that I got was building my own cable and then logging with the iiic.

I then had a seperate cable that plugged into the cigarette lighter for charging the palm when it ran out.

I am a bling kind of guy when it comes to my car, like it or hate it, that is just me. This is why I am asking.

I want it on all the time without fail.

I am also an electonics and IT guy so I guess that I could really go deeper in my investigation and find out.

I just didn't want to reinvent the wheel if one of you has managed to log and charge at the same time.

Thanks you for any thoughts.

I'd like to do this as well. Annoying having to re-sync my PDA everytime my batteries go dead.

Yes, well I think that we want the same thing for different reasons.

I found this BTW.

When I get around to it, I am confident that I can make this happen!

Palm M515 serial pinout..? - 3000GT/Stealth International Message Center

Yes It can be done.
I did it on my PALM IIIc.
Just opened the connector (palm side) and soldered a pair of wires to the power connections and then to a cigarrete lighter charger.

The palm serial cable I had had a kind of connector that can be disassembled, not shure if the one You have is one piece or what.

So why not use the 12v power source and ground the cable picks up from the fuse block and diag. port. Then just tap them into the battery terminals?

Because the palm uses 5v instead of 12v basically haha

Ah gotcha... was thinking you were just using the cig lighter as a plug and running 12v through it. Good idea, I'll give it a go.

It's been a while since I wired it, but it works nicely. You can get a cable for the IIIc that has a 12V charger plug built into it. You just modify that and wire it directly to 12V inside the console or wherever.

I built a mounting bracket for mine that bolts to the side of the console, and the cable runs into the console through the coin holder into the console and under the dash to the diagnostic port. The power is spliced into the cable out of sight in the console. Palm is always on and charging when the car is running.

Works great...although now I rarely have it hooked up (usually a laptop with Link)
