5.3 Notion of read modes
During asynchronous read (or default read), the reader continuously tries to read
all tags in the RF eld. Several options can be applied that modify the reader’s
behavior during asynchronous read:
●
“Multiplexer”: If this mode is active, the reader uses the multiplexer instead
of the default RF configuration for reading. The multiplexer makes it possible
to dene a sequence of antennas, tag types and RF output powers that will be
automatically used during the reading process. For example, a user can congure
the multiplexer so that reader tries to read ISO15693 tags for 100ms on channel
1 at 1Watt, then ICode UID tags for 50ms on channel 1 at 2Watts, then ISO15693
tags for 100ms on channel 2 at 1Watt, then ICode UID tags for 50ms on channel
2 at 2Watts.
●
“Input triggered”: If this mode is active, the reader waits for GPIO Input #1
to become active in order to activate the RF eld and sta reading. When GPIO
Input #1 gets back to inactive state, RF eld is turned o and the reader stops
reading until input is active again.
