4. What is the cradle?

• It is a cable with a fancy connector at one end and a button.
  Check the following table for pin assignments.
  

  DB9F	Signal	Cradle	Signal
  1	CD
  2	RXD	6	TXD
  3	TXD	8	RXD
  4	DTR
  5	GND	1	GND
  6	DSR	10	Gen.Purpose Output
  7	RTS	5	CTS
  8	CTS	7	RTS
  9	RI
  Shield	10nF capacitor to ground
  		4	HotSync switch
  		9	HotSync switch live (to 3.3V via 330 ohms)
  		3	Gen.Purpose Input
  		2	NC

OK. Now that you know pin assignments it is time to have some fun !

Pilot is very smart, try this:

Open a paper clip and insert it between holes 2 (RXD) and 3(TXD) of DB9F connector short-circuiting them.
Put Pilot on the cradle and press HotSync button.

Isn't it smart ?

" Here's something I've found:
Pin 4 (on the back of the Pilot) is the HotSync input; pin 9 is +3.3V. As you know, when they're connected, the Pilot starts a desktop HotSync. If Pin 3 (GP Input) and 4 are both connected to pin 9, the Pilot will do a Modem Hotsync.
On the PalmPilot one can change what the "Cradle HotSync button" and the "modem hotsync button" does; i.e., run something other than HotSync. So,depending on whether the GP Input is active or not, the Pilot can do two different things."

Thank you James on this tip !
