5.3 LSR116 illumination
The standard method of reading barcodes cycles the illumination on and off. You can control
illumination for various different applications using the commands in Table 4. For example, it is often
beneficial to turn off the illumination to prevent reflections from shiny surfaces, for example, mobile
phones.
Table 4. Illumination commands
Command
Description
Default
Parameters/Range
AISILL
Adaptive illumination mode (see page
21).
2
0 - Off (Phone only)
1 - Off (Paper only)
2 - On (Paper optimised)
3 - On (Phone optimised)
AISONT
Illumination on time.
Applies to AISILL modes 2 and 3 only
(adaptive illumination on).
Each unit is equivalent to 100
milliseconds.
8
0–200
AISOFT
Illumination off time.
Applies to AISILL modes 2 and 3 only
(adaptive illumination on).
Each unit is equivalent to 100
milliseconds.
8
0–200
AISONM
Illumination on mode.
When set to 0, the timing for the
illumination on period is set to a single
value, AISONT.
When set to 1, the illumination on period
cycles continuously (while triggered)
through the three AISONx values.
0
0 - Normal adaptive
operation; uses AISONT
timing
1 - Cycles through
AISON1 to AISON3
timings
AISON1
Illumination on time 1.
Applies to AISILL modes 2 and 3 only
(adaptive illumination on).
Each unit is equivalent to 100
milliseconds.
1
0–200
AISON2
Illumination on time 2.
Applies to AISILL modes 2 and 3 only
(adaptive illumination on).
Each unit is equivalent to 100
milliseconds.
2
0–200
AISON3
Illumination on time 3.
Applies to AISILL modes 2 and 3 only
(adaptive illumination on).
Each unit is equivalent to 100
milliseconds.
5
0–200
AISOFM
Illumination off mode.
When set to 0, the timing for the
illumination off period is set to a single
value, AISOFT.
When set to 1, the illumination off period
cycles continuously (while triggered)
through the three AISOFx values.
0
0 - Normal adaptive
operation; uses AISOFT
timing
1 - Cycles through
AISOF1 to AISOF3
timings
