Serial Data
Serial Data is effective in a highly controlled environment where the host
Usage:
knows precisely when the object is in the scan zone. It is also useful in
determining if a No Read has occurred.
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 Data and External Edge
Usage: Serial Data and External Edge is seldom used but can be useful in an
application that primarily uses an external sensing device but occasionally
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.
Definition: In this mode the scanner accepts either a serial ASCII character or an external
trigger pulse to start the read cycle.
