Trigger Mode
Serial Data
Definition: In Serial Data, the scanner 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 corner brackets, such as <t>.
Usage: Serial Data is effective in a highly controlled environment where the
host knows precisely when the object is in the scan zone. It is also use-
ful in determining if a noread has occurred.
Serial Cmd: <K200,4>
Serial Data or External Edge
Definition: In this mode the scanner accepts either a serial ASCII character or an
external trigger pulse to start the read cycle.
Usage: Serial Data or External Edge is seldom used but can be useful in an
application that primarily uses an external sensing device but occasion-
ally needs to be manually triggered.
An auxiliary terminal can be connected to the aux port so the user can
send the serial trigger character through the scanner to the host.
Serial Cmd: <K200,5>
