Batch Mode - Baracoda USB Plug User Manual

2.4 Batch mode

The batch mode can be used with scanners supporting it:
- Roadrunners (CPU firmware version 3.20 and higher)
- BaracodaPencil2 (firmware version 1.10 and higher)
This functionality is only available for USB Plug&Scan dongles with firmware version 3.10 and higher (see
§6.3 for how to get the firmware version).
When this mode is set, all the scanners (supporting the functionality) working with the dongle are in batch
mode: all scanned data is stored in the flash memory.
The stored barcodes can be discharged by scanning the following barcode:
The upload process consists in switching temporarily the scanner into Real time with "no data loss mode"
ON (all the barcodes in memory will be sent using the no data loss protocol). Then the scanner switches
back to batch mode when all the barcodes are properly sent.
NOTE:
The barcode upload process can stress the host and, depending on the host type, the below barcodes
may be necessary.
Indeed, the USB Plug&Scan dongle emulates a Keyboard. Thus, it has to send characters with a minor
delay between them. If the delay is too short or if the host is too slow or too busy to process the incoming
characters, some data can be lost by the host.
To avoid that phenomenon, the USB Plug&Scan can handle different keyboard emulation speeds:
Keyboard emulation speed : SLOW
Intercharacter delay = 20ms
