Pinout Palm V Pigtail:

Count pin numbers from front-connector left to right (like cradle front-view - Pin1/DTR left), looking at the back of your Palm device from right to left. Double check!!

Pin #	Palm V Signal	Colour
1	DTR (Out)	yellow
2	VBATT+ charging input for LiION cell	red (thicker wire)
3	ReceiveData (In)	green
4	RTS (Out)	blue
5	TransmitData (Out)	purple
6	CTS (In)	grey
7	GPI1 (In) -> HotSync button	no conection
8	GPI2 (In) -> Modem HotSync/ CradleDetect	brown
9	Unused	no connection
10	SignalGround / VBATT-	black (thicker wire)/orange/white

Colours on Palm V pigtail are different from Palm III pigtail!!

If you want to use pin7 for an external hotsync button, open the Palm V connector carefully with a knife around the edges and connect orange or white from pin10 to pin7.

Pin 2 (red) and pin 10 (black) are of thicker wire, because they carry the charging current for the internal LiION battery.
Be careful with this red wire if you leave the ends open or cut them - a good idea is to leave this wire slightly longer than the other cut / uneeded cable ends. A small pinpoint of glue to the tip of the cable end is also useful. Your Palm V won't like getting short circuited ...

Cable screen is not connected at all on PalmV side - if you want screening, connect it to physical ground at other cable end, e.g. to the connector frame on DB9 or DB25 connectors.

Don't blame me if you blow your Palm!
