Read Cycle

Number of Symbols

Usage: Commonly used in shipping applications where an object contains individual

symbols for part number, quantity, and other values.

Definition: This feature allows one trigger event to decode all symbols present.

Conditions: The following conditions apply:

• When Number of Symbols is set to Single, the read cycle ends when

one symbol is decoded and output.

• When Number of Symbols is set to Multiple, all decoded symbol data

(for both the same and different symbols) is output while the read cycle

is active and/or no timeout has occurred.

• If set to Multiple and Time Between Identical Decodes is less than

the decode time (typically about 4ms), the same symbol data can be

output multiple times.

Definition: Number of Symbols is the number of different symbols that can be read in

a single read cycle.
