Pages
This parameter determines the number of host screens (or pages) stored at
the terminal, to a maximum of 16.
The 9150 reduces data transmitted to the terminals by using the terminal’s capability
to store a page of data for each screen it displays. The 9150 maintains an image of
each page stored at the terminal. After receiving an application screen, the 9150 tries
to match the screen with a stored page.
If a similar page is already in the terminal’s memory, the 9150 instructs the terminal
to re-display its copy of the page; only the necessary changes are sent from the con-
troller. If no match is found, the complete page is sent to the terminal over the
radio link.
Note: There is a corresponding parameter on the terminal itself, and the actual
number of saved pages will be the smaller of the two values.
Transmit Line
When this feature is enabled, all modified data at the terminal will be automatically
transmitted when the operator enters data into a transmit-upon-entry field.
The value in this textbox specifies the line on the screen which is designated the
transmit line. The last entry field above or on the transmit line on the screen will be
identified as the transmit-upon-entry field. If any entry fields exist on lines below
the transmit line, no entry field will be designated as the transmit-upon-entry field.
A value of 0 (zero) disables this feature. A value of 24 will cause the last entry field
on each application screen to be defined as transmit-upon-entry.
AIAG
This parameter provides auto-locate and fill for input coming from bar code readers.
When bar code data is entered at a terminal, the terminal searches for “AIAG” fields
on the current page that can accept the bar code data. The data preloaded into the
“AIAG” field by the application program determines whether or not the bar code
data is accepted.
At the 9150 mini-controller, a decimal value of an ASCII character from 0 to 127
is set to match the “AIAG Field Identifier” set at the host. A value of 0 disables
this feature.
