Security Overview
The HS Compact Handheld transmitter uses the
®
HS Series encoder, which is based on CipherLinx™
technology. CipherLinx™ is a high-security encryption
algorithm and wireless protocol designed for remote
CipherLinx
control and remote keyless entry applications. It
Technology
provides a much greater level of security and many
more features than older technologies on the market,
Figure 4: CipherLinx Logo
such as fixed address or “rolling code” systems.
Additionally, the CipherLinx™ transmission protocol is much more
advanced than the simple PWM method employed by many systems. By
utilizing an advanced serial protocol for data, CipherLinx™ is able to offer
superior noise immunity, greater range, and increased link reliability, all of
which are key factors in a wireless system.
In addition to this high level of security, CipherLinx™ also offers a number
of features that are unique among remote control products. These include
a large number of data lines, internal key generation, “button level” control
permissions, an optional encoder PIN, as well as the ability for the decoder
to identify the originating encoder. Please refer to the HS Series encoder
and decoder data guides for full details.
CipherLinx™ never sends or accepts the same data twice, never loses
sync, and changes codes with every packet, not just every button press.
CipherLinx™ encryption is based on the Skipjack cipher developed by
the U.S. National Security Agency (NSA), and is widely considered one of
the most secure ciphers available. There have been no known successful
attacks on the full Skipjack algorithm. Skipjack is a block cipher that has
80-bit keys and 64-bit data blocks. Since each packet is longer that 64
bits, Skipjack is employed in an encryption mode. The particular encryption
mode chosen for CipherLinx™ is based on the CMC encryption mode, so
that the resulting cipher is a special kind of function known as a “strong
PRP” (sPRP). The encryption mode uses several invocations of Skipjack to
encrypt the 128 bits in each message.
The Skipjack algorithm used by Linx has been proven secure and is
not modified to avoid any compromise of strength. CipherLinx™ is far
more than just a Skipjack implementation. CipherLinx's patent-pending
technology combines multiple calls to the encryption algorithm with a
proprietary mixing algorithm. CipherLinx™ encryption, as implemented
in the Linx HS Series, has been independently evaluated by Independent
Security Evaluators (ISE), a respected security firm that is widely
recognized for its expertise in electronic security. They concluded that “the
CipherLinx(TM) protocol in the HS Series is well-designed and is an excellent
choice for applications requiring a secure unidirectional link.” ISE’s full
evaluation report can be found at www.linxtechnologies.com. In summary,
CipherLinx™ is a powerful, independently verified, secure encryption
technology that is well-suited to a wide range of applications.

Typical System Setup
The HS Series Compact Handheld Transmitter is intended to make user
setup straightforward while ensuring the highest possible security. This
inherent ease of use can be illustrated by a typical user setup. The Typical
Applications section of the HS Series Decoder Data Guide shows the
circuit schematics on which the receiver examples are based.
1. Create an exchange a key from
GET_KEY Button
a decoder to the transmitter.
The handheld transmitter includes
an on-board infrared receiver
MODE_IND
designed to optically receive
Window
the decoder’s key transmission.
Sending the key in this manner
CREATE_PIN
preserves security while
Button
avoiding the need for a hardwire
connection.
Figure 5: Button Access Holes
The high security key is created and exchanged by placing the decoder
in the Create Key Mode. The decoder’s MODE_IND LED lights to
indicate that the decoder has entered Create Key Mode. The decoder’s
CREATE_KEY button is then pressed ten times to create the key. After
the tenth press, the MODE_IND LED turns off and the decoder outputs
the key via a 900nm infrared diode on the KEY_OUT line. A paper clip
is used to press the GET_KEY button on the back of the transmitter.
Hold the back of the transmitter near the decoder’s infrared diode
within twenty seconds. Once the key has been transferred, the MODE_
IND LEDs on both the transmitter and decoder illuminate to indicate
success.
2. Establish Control Permissions
Next, the user defines which buttons on the transmitter should be
acknowledged by the decoder. The HS Series Control Permissions
allow each transmitter in a system to activate different data lines.
This is especially useful in applications where differing user access or
activation capabilities are desired.
Consider this example: a three-door garage houses Dad’s Corvette,
Mom’s Mercedes, and Son’s Yugo. With most competitive products,
any keyfob could open any garage door as long as the addresses
match. In an HS-based system, the keyfobs could easily be configured
– 6 –
to open only certain doors (guess which one Son gets to open!).
Setting the control permissions is intuitive. The user presses the
decoder’s LEARN button. The decoder’s MODE_IND LED starts
flashing and the user simply presses the handheld transmitter buttons
that should be recognized. Control Permissions are stored when
the LEARN button is pressed again or automatically after seventeen
seconds.
There are other powerful options, such as programming a user PIN or
copying a decoder, but these two steps are all that is required for a
typical setup.
Using the Optional Keypad Pin
For higher security applications, the HS Series encoder has the option to
set a Personal Identification Number (PIN) to control access to the encoder.
This PIN is a four-button combination of the eight buttons which must be
entered before the transmitter will send any commands. It needs to be
re-entered after fifteen minutes of inactivity. If no PIN is created, then the
transmitter activates as soon as a button is pressed.
Creation of a Keypad PIN
1. Use a paper clip to press the CREATE_PIN button on the back of the
transmitter. The MODE_IND LED begins flashing until either a PIN is
successfully entered or fifteen seconds has passed.
2. To enter the PIN, press a sequence of any four buttons. The MODE_
IND stops flashing and the PIN is created.
3. To cancel Create PIN Mode prior to the fourth entry, either wait for the
fifteen second timeout to pass or press the CREATE_PIN button. The
MODE_IND LED stops flashing and no PIN is created.
4. If a new KEY is created, the PIN is automatically erased.
Using the PIN
1. The PIN is entered by pressing each button until all four entries have
been made. There is a maximum two-second time limit between
entries, after which the PIN must be re-entered in its entirety.
2. Once the PIN is successfully entered, the transmitter is operational
unless it is inactive for fifteen minutes, in which case the PIN must be
re-entered.

Contention Considerations
Assembly Diagram
It is important to understand that only one transmitter at a time can be
activated within a reception area. While the transmitted signal consists
of encoded digital data, only one carrier of any particular frequency can
occupy airspace without contention at any given time. If two transmitters
are activated in the same area at the same time, then the signals will
interfere with each other and the decoder will not see a valid transmission,
so it will not take any action.

IC: 5840A-CPMSXXXA
Battery Replacement
The remote unit utilizes a standard CR2032 lithium
button cell. In normal use, it provides 1 to 2 years of
operation. To replace the battery, remove the access
cover by pressing firmly on the label area and sliding
it off. Once the unit is open, remove the battery by
sliding it from beneath the holder. Replace it with
the same type of battery while observing the polarity
shown in Figure 6.

The Decoder Board
The decoder board has six main sections of interest: the decoder area, the
RF area, the USB area, the key exchange area, the power supply and the
prototyping area.
The Decoder Area
Figure 9 shows the decoder area of the development board.
There is one function switch to the left of the CREATE button. BSEL0 is
used to set the baud rate of the decoder as described in Figure 10. The
transmitter is set to 4,800bps, so this switch must be in the down position.

The Decoder Board RF Area
Figure 11 shows the RF area of the development board.
Figure 9: The Decoder Area
The decoder is located in the center beneath the Linx logo. To the left are
LEDs which are connected to the decoder data lines. These light up when
the decoder receives a signal from the encoder to take the data line high.
LED D0 corresponds to data line D0, and so forth.
Beneath the decoder is an LED that is connected to the MODE_IND line.
This lights up as described in the HS Series Decoder Data Guide.
Figure 11: The Decoder Board RF Area
This board is populated with the LR Series receiver. The ANT1 connector is
provided for attachment of the included antenna.
Beneath the LED are three buttons. The one on the left labeled HS_SEND_
KEY is connected to the SEND_COPY line on the decoder. The one in
the middle is connected to the LEARN line, and the one on the right is
connected to the CREATE_KEY line. The HS_SEND_KEY button causes
the decoder to begin sending a copy of its User Data when pressed at the
same time as the LEARN button. The LEARN button is used to learn the
Control Permissions from the encoder and, with the other two buttons, to
make the decoder enter special modes. The CREATE_KEY button causes
the decoder to create a new key when pressed at the same time as the
LEARN button. All of these functions are described in detail in the HS
Series Decoder Data Guide.

– 11 –
The Decoder Board USB Area
The decoder development board has a Linx SDM-USB-QS-S module for
use with the included development software. This module is powered by
the USB bus, so it does not pull any current from the battery. Figure 12
shows the USB area on the decoder board.
The Power Supply
The power supply consists of a 9V battery and a power jack connected to
a 3.0V voltage regulator. The regulator can provide approximately 500mA of
current to the prototyping area. If the added circuitry needs more than this,
then an external supply must be added. If the circuit consistently draws
more than 100mA of current, it might be better to use the power jack, as
the battery will run down fairly quickly, reducing testing and development
time.
The jack accepts a standard 5.5mm plug with the tip ground and the outer
shell 7 to 16VDC positive supply. A reverse voltage protection diode has
been included on the board to protect the circuitry in case the voltage on
the plug is reversed, but it is still a good idea to double-check the polarity.
Figure 12: The Decoder Board USB Area
The microcontroller on the right monitors the decoder data lines and
generates commands that are sent to the development software on the PC
via the QS Series USB module. The RX_IND LED to the left of the module
flashes to indicate that data is being received from the microcontroller.
The Decoder Board Key Exchange Area
Figure 13 shows the key exchange area of the development board.
Figure 13: The Decoder Board Key Exchange Area
The key is created in the decoder and transferred to the transmitter with an
infrared (IR) link. This consists of an infrared diode (IR2) that is modulated
by the KEY_OUT line of the decoder and an infrared receiver built into
the transmitter. Once the key is created, the decoder outputs the key
information through this circuit. The clear plastic window on the back of
the transmitter should be held within a few inches of the infrared diode
and the key transfer happens automatically. Jack J4 is also connected
to the KEY_OUT line and is available for wired transfer of the key, but the
handheld transmitter is not adapted to accept a wired connection. The rest
of the circuitry is used for sending and receiving copies of the decoder’s
User Data, as described in the HS Series Decoder Data Guide, but is not
required for operation of this development system.
– 12 –
Figure 14: The Power Supply Area
– 13 –
The Prototyping Area
The prototyping area contains a large area of plated through holes so
that external circuitry can be placed on the board. This circuitry can be
interfaced with the HS decoder through the breakout header to the right. At
the bottom of this area is a row connected to the 3V power supply and at
the top is a row connected to ground.
All of the data lines are connected to a wire-wrap header to the right,
allowing easy access from the prototyping area. The decoder DATA_IN and
TX_ID lines are also available on the header, as well as the PDN line from
the receiver. This allows complete control of the entire system from the
prototyping area, giving the designer a great deal of flexibility in using the
boards.
Installing the Software and Drivers
The Master Development System uses the QS Series USB module to
provide a simple serial interface to a PC via a USB connection. The module
requires drivers to be installed on the PC before it can function properly.
The QS Series Drivers are included on the CD with the software.
The first time the QS module is plugged into the computer, Windows
displays the Found New Hardware Wizard, which guides the installation
of the drivers. Application Note AN-00201 describes the installation of
the drivers in detail. The drivers should be installed before running the
Development Software.
The HS Master Development Software automatically starts when the CD is
inserted and the player in Figure 16 appears.

The second mode is for use with the Master Development System. When
the decoder board is plugged into a USB port on the PC, the transmitter
can be used to activate the features in the software. If the LEDs on the
evaluation board turn on, then the LEDs in the program turn on and
activate the corresponding data line function.

The Master Development software can be used in one of two modes.
The default mode is a software simulation of the system and does not
require any hardware. It simulates two handheld transmitters as well as two
