4.2 PEN PARAMETERS
4.2.1
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 of the physical resolution of the code read.
The shortest pulse (200
μ
s) corresponds to 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.
4.2.2
Conversion to Code 39
When using these readers it is possible to convert all codes to Code 39. By disabling
this option the decoded codes will be transmitted in their original format; except for
the following codes which are ALWAYS converted into Code 39 format:
MSI, Plessey, Telepen, Delta IBM, Code 11, Code 16K, Code 49 and RSS Codes.
4.2.3
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.
