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.
