Wand Emulation
The Wand Emulation interface transmits decoded bar code data
to a decoding device by emulating the digital output of a wand.
Large messages are broken down into data blocks that are
transmitted as individual wand scans.
4.6.4.1
Characters per Data Block
This programming selection allows you to set the size of the data
block which will be transmitted as a wand scan.
4.6.4.2
Delay Between Data Blocks
This programming selection sets the effective delay between
sub symbols.
4.6.4.3
Effective Output Scan Rate
This sets the transmission rate of the digital output signal. The
available parameters assume a bar code density of .010 inches
(10 mil).
4.6.4.4
Digital Output Signal Polarity
This programming parameter allows you to set the output logic
convention for the digital output. The choices are White High
(Laser Output) and Black High. Default = Black High.
