Learning About the Terminal 1

Use the following guidelines to achieve a successful scan:

•Hold the terminal so that the scanner is pointing toward the bar code label. Tilt the terminal up or down slightly (20 degrees).

•Optimum scan angles vary with the type and print quality of the bar code label, the distance of the scanner from the label, and the lighting in the area.

•Do not scan the bar code label “straight on.” In a 2-degree conical “dead zone” directly above the label, the laser beam may reflect back into the scanner window and prevent the terminal from reading the label. At certain angles and straight on, you may not see the laser beam.

Learning About the Connector Modules

The 243X has two different connector module options.

	Serial/Power		Serial/Power
Input device	connector	Input device	connector
connector		connector
	Standard		Serial
	Connector Module		Connector Module
	243XU009.eps		243XU007.eps

Standard Connector Module The input device connector on the standard connector module supports non-decoded input devices. For a list of these input devices, see “Input Devices and Cables” in Appendix A.

Serial Connector Module The input device connector on the serial connector module supports decoded input devices. For a list of these input devices, contact your local Intermec sales representative. You can also use the input device connector to connect to a serial device. For help, see “Connecting to a Serial Device or Network” on page 1-24.

Note: The serial/power connector and the input device connector lead to the same serial port, COM1. Do not connect more than one serial device to the 243X.

The 243X supports different bar code symbologies depending on the type of input device connected to the terminal. For a list of these symbologies, see “Bar Code Symbologies” in Appendix A.
