Crossed 10/100 Base-T Ethernet Cable
When testing, it may be convenient to connect the PocketPAD directly to a computer’s network
card without the use of a hub. This can be achieved using a crossed network cable wired as

Crossed Serial Cable
In order for a computer (or other device) to communicate with the PocketPAD’s RS232 serial
port, a simple 3-wire crossed cable is usually sufficient. (If hardware-based handshaking is
required then see Full Crossed Serial Cable.) The three wires should be connected as follows,
using either a 9-pin or 25-pin connector for the computer’s serial port.
