Psion Teklogix 8525/8530 Vehicle-Mount Computer User Manual
Note: This operation is only performed on screens received from the host. Data sent
to the host remains unaffected.
Passthru Printing
Setting this parameter to ‘Y’ allows the host to send data directly to the 8525/8530
serial port. This option is most commonly used for printing.
AIAG Character
This parameter is used to enter a decimal representation of the ASCII character code
of the AIAG character. A value of 0 (zero) disables this feature.
When a bar code data is scanned, the 8525/8530 searches for AIAG fields on the
current page that can accept the bar code data. The application program
distinguishes an entry field as AIAG by preceding the field with this special mode
character which indicates the existence of AIAG fields.
Barcode Character
Barcode-input-only fields are special entry fields that only accept input from a bar
code reader. The application program identifies a barcode-input-only entry field by
preceding the field with a special character.
This parameter is used to enter a decimal representation of the ASCII character code
of the barcode-input-only character. A value of 0 (zero) disables this feature.
Serial IO Character
Serial I/O fields are special entry and fixed fields that accept input from and output
to a serial port. The application program distinguishes this field as Serial I/O by
preceding the field with a special character. If this character precedes a fixed field,
the data will be sent to the 8525/8530’s serial port. If it precedes an entry field, the
field accepts data from the 8525/8530’s serial port.
This parameter allows you to enter a decimal representation of the ASCII character
code of this special character. A value of 0 (zero) disables this feature.
Fixed Field Ovrhd
This parameter defines the maximum number of characters allowed within two
adjacent, fixed fields that can be sent as a single field. For example, if two fields are
4 characters apart and this parameter is set to 5, these fields are joined into a single
field of data. The allowable range for this field is 0 to 80.
This feature affects fields with the “Normal” display attribute only.
