How you can use your IPAQ 5450 Carddle to connect anything to your IPAQ.

Connector Pin out:

V_ADP V_ADP V_ADP V_ADP Reserved RS232 DCD RS232 RxD RS232 TxD RS232 DTR GND RS232 DSR RS232 RTS RS232 CTS RS232 RING GND (NC) No Connect USB Detect NC USB - UDC + NC USB - UDC - GND

How to find the pin-numbers?

All you need is a DVM with Resistance Measurement and a small copper wire (with un isolated ends). The rest is precise work. To get the correct pin i used my digicam to photograph the wire, zoomed into the picture on my display and counted if the wire is placed correct. Then with the DVM you can find the corresponding pin on the other side.
