2.3 PEN EMULATION PARAMETERS
2.3.1
Minimum Output Pulse
This parameter sets the duration of the output pulse corresponding to the narrowest
element in the barcode. In this way the code resolution is controlled by the signal
sent to the decoder, independently from the physical resolution of the code read.
The shortest pulse (200 µs) corresponds to a high resolution code emulation and
therefore a shorter transfer speed to the decoder (for decoders able to work on high
resolution codes). Likewise, longer pulses correspond to low resolution code
emulation and therefore a longer transfer time to the decoder.
2.3.2 Overflow
This parameter generates a white space before the first bar and after the last bar of
the code. The selections are as follows:
narrow
= space 10 times the minimum output pulse.
medium = space 20 times the minimum output pulse.
wide
= space 30 times the minimum output pulse.
2.3.3
Conversion to Code 39 and Code 128
This parameter allows converting the decoded codes into either Code 39 format or
Code 128 format. It is not possible to disable conversion.
