Barcode
Barcode-input-only fields are special entry fields that only accept input from a bar
code reader. The application program distinguishes an entry field as barcode-input-
only by preceding the field with a special character.
The range for this parameter – 0 to 127 – represents the decimal values of ASCII
characters. A value of 0 (zero) disables this feature.
Entry Line
This parameter contains the number of the first line displayed if there is no entry
field in the upper-left portion of the screen, and if an entry field is at or below
this line.
The Entry Line parameter allows an automatic offset within the host screen, so that
the area displayed by the terminal includes an entry field that would normally be out
of bounds. Normally, Teklogix terminals only display the upper-left corner of the
application screen because of their smaller display size.
Field Overhead
This parameter contains the maximum number of characters allowed between two
fixed fields which still allows the 9150 to join them into one field.
Sometimes the 9150 will join two adjacent fixed fields and then send them as one
field. This reduces the overhead on the radio link.
For example, if two fields were 4 characters apart and this parameter was ‘5’, then
these fields would be joined into one.
Command Region
This parameter defines a region of the host screen which the 9150 will examine for
the presence of reserved commands.
The four numbers in the Command Region textboxes represent the row and column
addresses of the upper left corner and the lower right corner of the command region.
The first textbox of each pair contains the row number; the second contains the
column number. The range of row values is 0 to 24; column values are 0 to 80.
To define the last two lines of the host screen as the command region, for example,
enter the values 23, 1 and 24, 80.
