Appendix I
Handheld Data Format Requirements
This appendix provides application notes to describe the general format of data that can be accepted by the scanner
through the auxiliary port as transmitted from a handheld scanner.
Handheld Data Format Requirements General
• 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 trans-
mission, and de-asserted after label transmission is complete. No other flow control mechanisms are required
or supported.
• Symbologies requiring fixed lengths (UPC/EAN) will enforce length requirements for validation of the label.
• Handheld 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 validated).
• Standard Datalogic formats generally use a single prefix character. The specific formats are provided below.
