HS Series
Remote Control Decoder
Data Guide
Warning:
Some customers may want Linx radio frequency (“RF”)
products to control machinery or devices remotely, including machinery
or devices that can cause death, bodily injuries, and/or property
damage if improperly or inadvertently triggered, particularly in industrial
settings or other applications implicating life-safety concerns (“Life and
Property Safety Situations”).
NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE
SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY
SITUATIONS.
No OEM Linx Remote Control or Function Module
should be modified for Life and Property Safety Situations. Such
modification cannot provide sufficient safety and will void the product’s
regulatory certification and warranty.
Customers may use our (non-Function) Modules, Antenna and
Connectors as part of other systems in Life Safety Situations, but
only with necessary and industry appropriate redundancies and
in compliance with applicable safety standards, including without
limitation, ANSI and NFPA standards. It is solely the responsibility of any
Linx customer who uses one or more of these products to incorporate
appropriate redundancies and safety standards for the Life and
Property Safety Situation application.
Do not use this or any Linx product to trigger an action directly
from the data line or RSSI lines without a protocol or encoder/
decoder to validate the data.
Without validation, any signal from
another unrelated transmitter in the environment received by the module
could inadvertently trigger the action.
All RF products are susceptible to RF interference that can prevent
communication.
RF products without frequency agility or hopping
implemented are more subject to interference. This module does not
have a frequency hopping protocol built in.
Do not use any Linx product over the limits in this data guide.
Excessive voltage or extended operation at the maximum voltage could
cause product failure. Exceeding the reflow temperature profile could
cause product failure which is not immediately evident.
Do not make any physical or electrical modifications to any Linx
product.
This will void the warranty and regulatory and UL certifications
and may cause product failure which is not immediately evident.

Mode Indicator Output. This line activates
when a valid transmission is received, when the
decoder enters Learn Mode, Get Key Mode,
Create Key Mode, or Send Copy Mode, and
when the memory is cleared. This allows for the
connection of an LED to indicate to the user
that these events are taking place.
Learn Mode Activation Line. When this line
goes high and is then pulled low, the decoder
enters Learn Mode to accept permissions from
an encoder and store it in memory. If it is held
high for ten seconds, the decoder clears all
User Data from memory. If it goes high while
the SEND_COPY or CREATE_KEY lines are
high, then the decoder enters Send Copy Mode
or Create Key Mode, respectively.
Data Input Line. This line accepts the encoded
serial data stream from a receiver.

Description
Data Output Lines. These lines reproduce the
state of the encoder's data lines upon reception
of a valid packet.
Baud Rate Selection Line. This line is used to
select the baud rate of the serial data stream.
If the line is high, the baud rate is 28,800bps,
if it is low, the baud rate is 4,800bps. The
baud rate must be set before power up. The
transcoder will not recognize any change in the
baud rate setting after it is on.
Send Copy Activation Line. When this line is
taken high while the LEARN line is high, the
decoder enters Send Copy Mode and outputs
the User Data on the KEY_OUT line. When
taken high while the CREATE_KEY line is high
at power-up, Send Copy Mode is disabled.
Ground
I
Copy Input Line. This line is used to input the
User Data from another decoder.
Create Key Activation Line. When this line is
taken high while the LEARN line is high, the
decoder enters Create Mode and creates a
key and encoder ID. It then sends these to
the encoder through the KEY_OUT line. When
taken high while the SEND_COPY line is high at
power-up, Send Copy Mode is disabled.
Key and Transmitter ID Output Line. When the
SEND_COPY line is high when the LEARN line
is taken high, the decoder outputs the User
Data on this line. This line also outputs the
transmitter identity upon reception of the first
valid packet of each session.

None of the input lines have internal pull-up or pull-down resistors. The input lines must
always be in a known state (either GND or V
CC
) at all times or the operation may not be
predictable. The designer must ensure that the input lines are never floating, either by us-
ing external resistors, by tying the lines directly to GND or V
CC
, or by use of other circuits
to control the line state.
