Learning About the Terminal
1-23

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.

Connector Module
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.
