Field Overhead
This parameter contains the maximum number of characters allowed between two fixed
fields which still allows the 9160 G2 to join them into one field.
Sometimes the 9160 G2 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 9160 G2 will examine for the
presence of reserved commands.
The four numbers in the Command Region textboxes represent the row and column ad-
dresses 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.
Currently, the only command supported is ALARM (refer to page 259 for details on this
command). When the word "ALARM" is placed anywhere within the command region, the
9160 G2 will send a TESS beep command to the mobile computer.
