Serial connections require a 9-pin serial communications (COM) port on your
desktop PC. If the 9-pin serial port is in use by another device, or if your
desktop PC has no 9-pin serial port, obtain an adapter from your computer's
manufacturer.
Connecting by cradle
If a cradle was not included with your HP Jornada 540 Pocket PC, you can
purchase a serial or USB cradle as an optional accessory. For more
information, see the HP Jornada Accessories Guide.
To connect by cradle
1. Connect the DC plug from the AC adapter to the DC jack on the
cradle cable, and plug the AC adapter into a wall outlet.
2. Connect the cable from the cradle to a serial or USB port on your
desktop PC.
3. Slide your HP Jornada into the cradle. Your HP Jornada should start
automatically and establish a connection to the desktop PC.
