Handheld Data Format Requirements

Handheld Data Format Requirements General

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 mechanisms are required or supported. The deasser-
tion of the RTS signal must occur no later than 50 milliseconds
from the complete transmission 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
characters for Codabar and Code 39 labels.
• Appropriate industrial length requirements will be enforced (if
configured) 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 val-
idated).
• Standard Datalogic formats generally use a single prefix char-
acter. The specific formats are provided below.
