Read Cycle
Serial Data
Note: In Serial Data , sending a non-delimited start serial character will start a read cycle;
however, a non-delimited stop serial character has no effect.
Serial Data and Edge
Note: In Serial Data , sending a non-delimited start serial character will start a read cycle;
however, a non-delimited stop serial character has no effect.
Continuous Read Auto
Usage: Serial Data is effective in a highly controlled environment where the host
knows precisely when the object is in the field of view. It is also useful in
determining if a No-Read has occurred.
Definition: In Serial Data , the reader accepts an ASCII character from the host or
controlling device as a trigger to start a read cycle. A Serial Data trigger
behaves the same as an External Edge trigger.
Serial commands are entered inside angle brackets, as shown here: <t> .
Serial Cmd: < K200, 4 >
Usage: Serial Data or External Edge is seldom used but can be useful in an
application that primarily uses an external sensing device but occasionally
needs to be triggered manually.
Definition: In this mode the reader accepts either a serial ASCII character or an external
trigger pulse to start the read cycle.
Serial Cmd: < K200, 5 >
Definition: Behaves identically to Continuous Read but maintains optimal self-adjusting
photometry parameters. As a result, the photometry parameters (Exposure
and Gain) in the <K541> command are continuously updated with the
optimal configuration. In this mode, the illumination does not strobe, but
instead is always active, as images are continuously captured.
Serial Cmd: < K200, 6 >
