I'm talking about the data connector on the Treo 650. Even the Hotsync cable uses only 5 of the 13 pins on the data portion of the connector (the power side has 3 pins).

Who/what uses the other 8 pins on the data connector? For what?

[KRamsauer]

A couple of them are for audio out.

[alokeprasad]

Any device uses these (off of the Universal connector, or whatever it's called)?

Most external speakers use the headset jack ...

[KRamsauer]

I don't know. It seems silly to have the headset jack down on the bottom along with the audio out of the universal connector, but that's Palmone for ya. The new connector was partly justified by them because it has audio out. Hahah, jokes on us.

And come to think of it, it may have a microphone on there too.

They are there to force you into buying only palm connectors LOL

I still don't know why palm or other pda don't use USB. it's faster,

The Multi-Connector supports both serial and USB....

Isn't that the "universal" (600) pin-out?

ok

but who really uses Serial, plus they have usb to serail adapters.

the treo should have a mini USB port, a seperate adaptor "barrel" slot, and Ear phone out.

[ERicJ]

Isn't that the "universal" (600) pin-out?

If so, it's coincidence. That table may (or may not ) have come from the P1 Developer Guide, Multi-connector spec.

[ERicJ]

Me. And most everyone else who syncs their Treo to a UNIX box.

USB to Serial adaptors don't work in that direction. They only work if the computer side is USB and the PDA side is Serial.

You're right. I get them mixed up. 600 had 15 pins. Once I noticed the "Shield" I realized you were right.

[khaytsus]

Me. And most everyone else who syncs their Treo to a UNIX box.

Yikes.. What are you syncing against, a really old Unix? Solaris, FreeBSD (and other BSDs), Linux, etc, all support USB perfectly.

My Clie before, and my 650, both synced against USB just fine in Linux using pilot-tools and jpilot. I got tired of the cable, so I set up BlueTooth, which again works great.

The Sun Ultra60 workstation (running Solaris8) doesn't have any USB ports.

Folks,

Serial is key for anyone that uses a Serial GPS unit with a Y cable in your car that also acts as a charger :-)

Personally I think you are absolutely right about that one. There is no other logical reason for them to have changed the connector from the Treo 600 to the Treo 650.

I still don't know why palm or other pda don't use USB. it's faster,

Actually the PalmOne Tungsten-E has a mini USB connector on the PDA. Which is what should have been on the Treo 650, that is if they had to change connectors from the Treo 600.
