Reader Multiplex Mode (Syncronisation)To enable more than one Reader to be used in close proximity, the RF operations executed by theReaders must be multiplexed to prevent unwanted interference.This is achieved by using the Multiplex (Sychronisation) Mode.In combination with Buffered Read Mode the Multiplex Mode allows maximum speed of operation. Inthis case each Reader passes control to the next after it has completed its task. This is effectively around-robin control, but it is much faster than single host control since it is controlled at a Reader lev-el.To setup the Multiplex (Sychronisation) Mode the Buffered Read Mode must be enabled in the 4.2.CFG1: Interface and 4.12. CFG11: Read Mode /Scan Mode – Read Data configuration block and theMultiplex Mode must be selected in the SYNC setting in the 4.19. CFG18: Reader Synchronisationconfiguration block. The Reader that should trigger the multiplex chain must be configured asMASTER in the SYNC setting in the 4.19. CFG18: Reader Synchronisation.In the Multiplex Mode the signal input IN and the signal output OUT on connector X5 are used forsynchronization cable connections. Please refer the manual “Mounting Instructions IDISC.LR(M)2000” (M51001-xde-ID-B.pdf / M51101-0de-ID-B.pdf) for details.Note:Multiplex Mode will only be available in Buffered Read Mode, Notification Mode and ScanMode.MultiplexReader 1MultiplexReader 3MultiplexReader 2IN1IN1 IN1OUT1 OUT1 OUT1
