Appendix G
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
•
RS232 - 9600 bps, 8 data bits, 1 stop bit, no parity.
•
RS-232 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 com-
plete.
No other flow control mechanisms are required or supported.
There must be a delay of at least 2 bit cell times (approximately 208 microseconds)
following the transmission of the last character before de-assertion of the RTS signal.
The de-assertion of the RTS signal must happen in less than 50 milliseconds after the
last character is transmitted.
•
USB handhelds enumerate as a CDC ACM serial device.
•
USB devices should also bracket the data with the RTS equivalent.
•
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 will be required to transmit start and stop characters for Codabar and
Code39 labels.
•
Appropriate industrial length requirements will be enforced (if configured) for valida-
tion 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. see specific formats
section.
•
Maximum label size allowed including identifiers is 2714 bytes
•
Recommendations:
•Handheld should not be configured for audible label read indication.
•Handheld should not be configured for visual label read indication.
•Handheld should not be configured for continuous label read mode.
