Datalogic Handheld Data Format Requirements

Product Reference Guide
This appendix provides application notes to describe the general format of
data that can be accepted by the scanner through the auxilliary port as
transmitted from a handheld scanner.
• 9600 bps, 8 data bits, 1 stop bit, no parity.
• RTS is used to "bracket" the data received from the handheld: RTS
must be asserted high during data transmission, and de-asserted
after label transmission is complete. No other flow control mecha-
nisms are required or supported. The de-assertion of the RTS signal
must occur no later than 50 milliseconds from the complete trans-
mission of the last character of the transmitted data.
• The time between character transmission can be no longer than 50
milliseconds.
• Symbologies requiring fixed lengths (UPC/EAN) will enforce length
requirements for validation of the label.
• Handheld scanner will be required to transmit start and stop charac-
ters for Codabar and Code 39 labels.
• Appropriate industrial length requirements will be enforced (if con-
figured) for validation of the label.
• Maximum label lengths will be enforced for label validation (i.e.
labels longer than the maximum label size will not be validated).
• Standard Datalogic formats generally use a single prefix character.
The specific formats are provided below.
The following sections describe label transmission formats that are typi-
cally observed in factory configurations of Datalogic handheld scanners.
