Read Cycle Differences in the MS-3 CCD

Important: With the MS-3 CCD, symbol data is output as soon as it is decoded. There
is no "end of read cycle" option. Because of this limitation, multisymbol operations can
only be emulated by controlling the read cycle duration and the time allowed between
identical consecutive decodes.
In read cycle timing, the MS-3 CCD differs from standard Microscan readers in the fol-
lowing ways:
1. In Single symbol mode, a read cycle ends only on a decode, falling trigger or a
timeout.
2. In Multiple symbol mode, the read cycle begins upon a triggered event, but
starts over after any symbol has been decoded.
3. There is no "new trigger" feature.
4. There is no timeout for level trigger read cycle mode.
In general, read cycle timeout and end of read cycle outputs are determined by
