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.
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 imager 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.
An auxiliary terminal can be connected to the auxiliary port so the user can
send the serial trigger character through the imager to the host.
Definition:
In this mode the imager accepts either a serial ASCII character or an external
trigger pulse to start the read cycle.
Serial Cmd:
< K200,5 >
