Connecting the Sony Clié to a Serial Port

Sony has two sets of Clié models, and each uses different cables. The PEG-N Series and PEG-S Series use the same serial cable while the PEG-NR Series, PEG-T Series, PEG-SL Series. The PEG-SJ Series use a different serial cable.

These cables, available from Clié dealers, bring the Clié serial port out to a DB9 female connector, configured as a DCE device. This allows the cable to be connected directly to a PC's serial port, which is configured as DTE.

This family of Palm devices supports lines TD, RD, RTS and DCE in addition to a non-standard support of DTR. These signals work at RS-232 compatible signal levels of ±5 volts. A USB cradle or cable for a Clié handheld cannot control another USB peripheral device. The Clié Hotsync® cradle is configured as a DCE device. Most likely, the device you are connecting to is also configured as DCE, so you will need to make a male to male null modem connection.
