Metrologic Instruments IS1000 manual Rolling Buffer Mode

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.
