Serial Commands
Binary Dip Switch
Some registers are what Microscan terms a 'Binary Dip Switch' where the value of each bit
of the data string switches on or off some part of the behavior of that register. The bits are
numbered from least significant to most (right to left). Each bit can be on or off (1 or 0).
An example of this is register 0B, 'Codabar Checksum'. The following settings are possible:
Bit (R to L)
0
1
Given the settings above, the binary string turns Codabar Checksum ON and strips it from
output.
Thus, the command to implement the settings above would be:
P(48)3
or
P(48)#03
Field of Interest
The reader optics are typically split into two separate fields - Field Of Interest 0 (FOI0) and
Field Of Interest 1 (FOI1). In certain circumstances, these fields can be customized to the
requirements of the user. In the default configuration of these fields FOI0 is the High Density
(HD) field and FOI1 is the Wide (W) field.
At a given focus distance, the HD field is designed to read small, low-mil symbols while the
Wide field is designed to pick up large, wide symbols.
This document will refer to FOI0 as HD and FOI1 as Wide.
