FEASA LED ANALYSER
FUNCTIONAL VERSION
Sequence Capture Mode
IdentifySequence - Identify the current sequence pattern
Transmit Receive
identifysequence ##
Where:
## represents the number of a stored sequence pattern and is a value in the range 00
– 20 which compares to the current sequence capture executed.
Description
This command compares the current sequence pattern with a stored list of patterns and
identifies it. The pattern is identified by a number in the range 00 – 20. Up to 21 patterns can
be stored. This feature allows the Analyser to identify patterns by comparing them against
patterns stored in memory.
The setsequencemode#, setsequencechannel@@, setsequencenumber###,
sequencecapture###, sequencenumber, sequencethreshold#####,
sequencestartdelay### and sequencewait### commands must be executed before this
command takes effect. Also, a capturesequence command must be issued before the
identifysequence command.
Example:
The PC transmits identifysequence to the LED Analyser to instruct it to identify the current
pattern and return its identity number.
