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.
Note: You should 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.
Scanning Options
You can set several configuration command parameters to configure the laser scanner to
meet your needs. There are several ways to set the scanner commands on the terminal.
For help, see Chapter 3, “Configuring the Terminal.” For help using the scanner
configuration commands, see Chapter 9, “Configuration Command Reference.”
The parameters available are:
Decode Security Defines the security level to use when decoding bar codes. When you
select a lower decode security level, the terminal can decode bar codes with poorer print
quality.
Scan Ahead Allows you to scan a number of bar code labels at one time. The labels are
held in a stack until the terminal can process the data.
Scanner Mode Defines how the scanner operates when you press the Scan button or
activate a cabled laser scanner. In One-Shot mode, the laser turns on and stays on until
you release the button or scanner trigger, or a label is decoded. In Automatic mode, you
can continuously scan bar code labels without having to release the button or scanner
trigger between labels.
Scanner Redundancy Defines the number of scans (voting) the scanner takes of the
same label. When set, voting requires the terminal to decode the same bar code label
multiple times during a single scanner event, and compare the decoded information for a
match before signaling a good read.
Scanner Selection Identifies the type of scanner you have connected to the TRAKKER
Antares terminal module for cabled scanners. The terminal can optimize the scanning
performance by using the scanner you define in this command. If you have a long range
or high density scan module, Scanner Selection lets you configure the spotting beam.
Scanner Timeout Defines the maximum length of time the scanner stays on each time
you press the Scan button or activate the cabled laser scanner.
Scanner Trigger Allows you to set the triggering to level or edge triggering. With level
triggering, you activate the scanner and the laser turns on and stays on until you release
the Scan button or the trigger on a cabled scanner. In edge triggering, you activate the
scanner and the laser turns on and stays on until you activate the scanner a second time,
or the scanner timeout turns it off.
