6.5. Rolling Buffer Mode
In this mode, the input data is first stored in the buffer of the decoder (up to 3K characters
maximum) and transmitted to the host system at a rhythm fixed by the inter-message time-
out selected on this page.
It can be useful when the data transmission speed to the host system is slow (specially in
Keyboard-Wedge mode) while a group of bar code labels has to be read very quickly
(example: carton on a conveyor…) or while a group of RS232 input messages has to be
first collected before transmission to the host system.
