So, a TagType of 3 (011
decimal
) indicates that the reader is looking only for
"Quark" and "Omega" tag types. Similarly, a TagType of 7 indicates it is looking
for all Class 1 / Gen 1 tag types, and a TagType of 4 indicates it is only looking
for "Lepton" tags. To enable Class 0 tags only, ensure bit #4 is on, which
corresponds to a TagType of 8. Similarly, TagType of 16 enables Class 1 / Gen 2
tags.
The allowable range of values for TagType depends on the capabilities
of the reader. For the ALR-9780, 8780, and 9640 the range is 1-7. For
the ALR-9770 the range is 1-15, and for the ALR-9800 the range is 1-31.
The ALR-8780 is only designed to read Lepton tags, so a TagType of 4
should be used for this reader.

AcqCycles takes a single integer parameter between 1 and 255. It is the number
of acquisition cycles that are performed each time the reader scans for Class1 /
Gen1 tags.
Note: While this attribute has a maximum value of 255 (as do the other
acquisition settings), setting them to high values can result in very long
acquisition times, which may cause the reader to appear non-responsive. For
example, setting both AcqCycles and AcqCount to 255 causes the reader to
perform more than 65,000 acquisitions when it is directed to look for Class1 /
Gen1 tags. The default value for AcqCycles is 1.
An acquisition cycle consists of a sequence of repeated wakes, reads, and
sleeps, depending on the AcqEnterWakeCount, AcqCount, and AcqSleepCount
parameters (below).
The AcqCycles parameter controls the "outer loop" of the acquisition cycle,
described in the "Tag Reading Fundamentals" chapter. Its value has a significant
impact on the time the reader takes to perform each scan for Class1 / Gen1 tags.
NOTE: Changes made with this command will take effect immediately.
