99 Decoder HD field (FOI0) Y Offset 0
Valid Range: 0 to 959 pixels
Decoder uses the pixels after the specified
pixel offset in the HD field (FOI0).
Also see registers: 53, 54, 98
9A Decoder Wide field (FOI1) X Offset 0
Valid Range: 0 to 639 pixels
Decoder uses the pixels after the specified
pixel offset in the Wide field (FOI1).
Also see registers: 9B, C7, C8
9B Decoder Wide field (FOI1) Y Offset 0
Valid Range: 0 to 959 pixels
Decoder uses the pixels after the specified
pixel offset in the Wide field (FOI1).
Also see registers: 9A, C7, C8
9D Target Tolerance (percent) 640 (#1600)
Valid Range: 0 to 7FFFFFFF Percent
For the Reader to accept a code, the
target dot must be within the code rect-
angle or in proximity to the symbol. The
nearness is defined as this percentage
of the code’s smaller dimension. For
example, with a 10 x 20 mm code and
a setting of 150 (%), the target dot must
be within 15 mm of the code.
Any value over 1000 is considered infi-
nite tolerance, and no target checking
is performed.
A2 Default Event Delay (ms) 64 (#100)
Valid Range: 0 to 7FFFFFFF Millisec-
onds
The Reader will pause for this amount
of time between each posting of the
default event (used with “continuous
read” mode).
Also see register C4
A7 Beep Pulse Separation (ms) 64 (#100)
Valid Range: 0 to 7FFFFFFF Millisec-
onds
The spacing in milliseconds between
beeps.
Also see registers: 26, 59
AC
Wide field (FOI1) Picture Window Left
Position
0
Specify left edge of window used with
“take picture.” The position and size
are relative to the virtual image (i.e.,
not the rotated physical image).
Note: Overall image is 960 pixels by
1280 pixels. Upper half is Wide field
(FIO1); lower half is High Density
(FOI0).
Also see registers: 36, 43, AD, AE, AF
