Serial Data
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

trigger
behaves the same as an
External Edge
trigger.
Serial commands are entered inside angle brackets, as shown here:

trigger pulse to start the read cycle.
