2.5. Reader Multiplex Mode
To enable more than one Reader to be used in close proximity, the RF operations executed by the
Readers must be multiplexed to prevent unwanted interference.
This is be achieved by using the Multiplex Mode.
In combination with Buffered Read Mode the Multiplex Mode allows maximum speed of operation. In
this case each Reader passes control to the next after it has completed its task. This is effectively a
round-robin control, but it is much faster than single host control since it is controlled at a Reader level.
To setup the Multiplex Mode the Buffered Read Mode must be enabled in the
3.10. CFG10: General
System Parameters
configuration block and the Multiplex Mode must be selected in the SYNC setting
in the
3.11. CFG11: Buffered Read Mode
configuration block. The Reader that should trigger the
multiplex chain must be configured as MASTER in the SYNC setting in the
3.11. CFG11: Buffered
Read Mode
configuration block.
In the Multiplex Mode the signal input IN1 and the signal output OUT1 are reserved for synchronization
cable connections. Please note that the signal input and the signal output are isolated and must be
supplied with external DC voltage. Please refer the manual “Mounting Instructions ID ISCLR200.x-x”
(M00601-xde-ID-B / M00602-xde-ID-B) for details.
Note:
Multiplex Mode will only be available in Buffered Read Mode.
