2.5 Installing in a System

Notes:

 Exercise caution at all times when working with AC-powered equipment.

 Turn off your devices before installation.

 Because of the special pin-out of the connectors, use the cables supplied by

the manufacturer.

 Do not modify the cable provided by the manufacturer. If you need a special

cable for some cases, contact your supplier to purchase the right cables or

technical support.

System Connection (Data Communication)

The PA series portable data terminals let you link to a host terminal through the CRD-22

cradle for data communication.

The CRD-22 cradle provides two methods for data transmission: through an RS-232 cable (9-

pin connector for PC and 9-pin connector for terminal) and through a USB cable.

Figure 2-9 System Connection

Notes:

 When both RS-232 and USB cables are connected between the CRD-22

cradle and host terminal, PA-20 can assign either USB or RS-232 interface for

data transmission.
