Extended Match Table and Counters
You can use the screen illustrated that follows to set up match code entries in
the Extended Match Code Table. You can define up to 128 entries here that
provide added flexibility in response to incoming data over the Primary
Match Codes described in the previous chapter.
Using Extended Match Codes you can compare all incoming data against
table entries that you create to meet your own unique needs. The decoder
can then count valid matches, and optionally fire one or more outputs.
Extended Match Codes provide a way to gather extremely detailed
information based on decoder activity, and to exercise an additional level of
control over decoder output activities.
The Extended Match Codes differ from the Primary Match Codes in a
number of ways
•
Extended Match Code counters appear on the same screen from which
they are controlled (the primary counters appear on a separate Status and
Primary Counters screen)
•
Extended Match Codes can activate multiple outputs, the duration of
which are defined in the Primary Match Code Table (Primary Match
Codes can each fire only a single output).
This screen displays the extended match code table in eight sets of sixteen
entries. Set one includes entries 1 through 16, Set 2 includes 17 through 32,
and so on. The entry numbers (1 through 128) appear on the left side of the
screen.
Screen Status
Parameters provide updates status, resetting
options, and access to all 128 extended
match code entries. Each set of 16 entries
can be individual enabled or disabled.
Extended Match Code Table
128 entries arranged in 8 screens of 16 each.

code symbology, as well as the 32-character
match table string are configured here.
Loading Counts
Individual counts and outputs are displayed here.
Each match can be simply counted, or may
additionally fire up to 8 discrete outputs. Outputs
may be fired together or in a round robin
sequence with each match.
