Note: Reflectance Threshold applies only to those MS-710 models that include an
MS-Sensor. See “MS-Sensor” on page A-24
.
To setup the MS-Sensor, select a number that is one or two numbers greater than the
value posted when nothing is in the scanner’s beam. See “MS-Sensor” on page A-

Scanner Type
Usage: Can be useful in certain application where extraneous objects in the field
of view might require a higher threshold.
Definition:
Determines the number of bar/space transitions that are sampled before
AGC can be resolved.
Serial Cmd: < KH symbol detect status, transition counter ,reflectance threshold>
Default: 14
Options: 3 to 255
Definition: The number is derived by testing the reflectivity of empty space.
Usage: Allows you to set the reflectance threshold—the level at which an object
is detected.
Serial Cmd: < KH symbol detect status,transition counter, reflectance threshold >
Default: 40
Options: 0 to 255
1. Reflectance can also be modified by sending the <KQ offset> test command which samples 50
scans for the highest reflectance value and adds a user-defined offset to this value.
Usage: This field is READ ONLY , and is set by a qualified technician during fac-
tory setup.
Definition: This field displays the current factory-set scanner density type.
Serial Cmd: < KPdensity >
Default: The default depends on the type of scanner that was ordered.
Options: 0 = Standard 1 = High Density
