DESCRIPTION OF FUNCTIONS
3.1
Master Transmitter
In learning mode the decoder can be set up so that the
first transmitter that is learned becomes the master
transmitter. The master transmitter will not be erased
when more than the maximum transmitters are learned.
The master transmitter can be used to implement
higher privileges in a system such as activating learn-
ing. When the master transmitter is activated the asso-
ciated function outputs as well as the MASTER output
are activated. To implement a master learn the MAS-
TER output can be inverted to control the LRNIN input.
3.2
Delayed Mode
The delayed mode can be used to implement a function
associated with activating a transmitter for an extended
period of time such as panic. Delayed mode is handled
differently for encoders with delay mode transmission
commands (NTQ106, HCS360/361) than encoders
without delay mode transmission commands (HCS200/
300/301). The DELAY output is activated when a “delay
transmission command” is received or when the same
transmissions are received consecutively for 4 sec-
onds.
3.3
Repeat
The REPEAT output is activated for 50 ms every time a
repeated code is received. The REPEAT output is also
used to indicate successful learning. The transmitter
should be activated during the first and second steps of
learning until the REPEAT output goes high.
3.4
Latched
The F1L (Function 1 latched) output can be used to
implement a nonvolatile latch function. F1L will change
state every time F1 is activated and return to the state
it was in after power loss.

OUTPUT MAPPING
The HCS509 supports the NTQ109’s output format.
These are: F1, F2, F1L, F3, REPEAT, MASTER, and
DELAY outputs. Additional to these outputs the
HCS509 also supports a binary output of the function
code [S3 S2 S1 S0] which allows the decoder to use all
the button codes of the new HCS encoders (Table 4-1).
