3 Basic Operation
3-3-4 Configure Read Cycle Settings
Introduction
The handheld can operate in a number of modes from a presentation scanner to a triggered handheld.
The Read Cycle defines how it will operate. Setting up the read cycle type and parameters involves a
series of decisions based on your particular application:
1
Select the Cycle type: Presentation, Triggered, or Start/Stop. Select the number of codes to
be read in a single cycle. The handheld can satisfy this condition by reading one or more codes
in a single image frame or across multiple image frames. The handheld will indicate a pass if it
finds all codes, and indicate a fail if it does not. Note that the handheld will not read and count a
code if it is the same code type, and if it contains the same data as a previous code.
Note: The pre-configured "recipes" in Assisted Setup all default to Start/Stop mode.
2
Decide how the read cycle will start by choosing the cycle type. If you choose Presentation, the
handheld will start automatically. If you choose Start/Stop, you will need to pull the trigger to
start the cycle. If you choose Triggered, you can either pull the trigger or send a serial trigger
via WebLink
(Non-Delimited).
Note: The reader can be triggered by a PLC via Power over Ethernet (PoE).
Common Settings for all Read Cycle Modes
The following settings are common for all read cycle modes:
• Look for # of Codes – This is the number of codes that the handheld should find in each decode
cycle. If the handheld finds all codes, the decode cycle will pass. If it does not find all codes, the cycle
will fail, and only the codes it finds will be output. The remaining codes will be output as No Read.
The maximum number of codes is 100.
• Configuration Database – Enable or disable the Configuration Database as part of the read cycle.
The Configuration Database is described in detail in Setup > Configuration Database.
The different read cycle types are listed below.
Presentation
In Presentation mode, by default the reader is in a Continuous-One free-running state.
Parts can be presented to the reader at will, and the number of codes to look for will equal 1. During the
cycle, the reader will continuously acquire and process images until all symbols are found, or until the
Timeout is reached. If the timeout is reached, Nothing was output will be displayed in the output data.
A Green Flash at the end of a cycle indicates a successful read.
The cycle time includes the Capture, Decode, Overhead Time, and Green Flash Duration.
• Green Flash – The reader flashes green at the end of a successful read cycle. The green LEDs
remain on for the set time. (0 msec to 655350 msec. The default is 250 msec).
