Chapter 23: Mini-Controller Configuration
5250 Emulation
The 9160 G2 reduces data transmitted to the mobile computers by using the mobile com-
puter's capability to store a page of data for each screen it displays. The 9160 G2 maintains
an image of each page stored at the mobile computer. After receiving an application screen,
the 9160 G2 tries to match the screen with a stored page.
If a similar page is already in the mobile computer's memory, the 9160 G2 instructs the
mobile computer to re-display its copy of the page; only the necessary changes are sent from
the controller. If no match is found, the complete page is sent to the mobile computer over
the radio link.
Note: There is a corresponding parameter on the mobile computer 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 mobile computer 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 mobile computer, the mobile computer 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 ac-
cepted. At the 9160 G2 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.
The format of the preloaded data is as follows:
<mode> <AIAG prefix(data)>
The mode character used with the command allows for different operating modes to suit
various application operations. The automatic locate and fill operation applies only to data
received from a bar code reader. Descriptions of the modes and AIAG prefix are listed in the
table below. These modes are set at the host.
