RF RECEIVER DECODER HYBRID. HIR6-433
Description
A range of miniature single in line (SIL) hybrid modules providing complete four channel Radio
Receiver/Decoder systems available in either AM or FM. When used with the 110-AM or 120-FM series
pocket keyfobs a complete remote telemetry system is obtained with up to 150 metres range.
The module consists of a front end super-heterodyne or super-regen RF receiver with an embedded
microcontroller decoding a highly secure Keeloq protocol signal.
The module has an easy-to-use 'LEARN' facility, and is capable of learning up to 50 unique keyfob encoders.
The module requires a 5V power supply and provides a direct LED drive showing data reception and four
digital data outputs. The outputs may be programmed for momentary or latching configuration.
The modules have flash re-programmability feature to enable field re-programming of the controller.

HiR6 Versions
This range of modules provides a very low power SuperRegenerative receiver, combined with flash
programmable controller, supplied pre-programmed to operate with a suitable Keeloq Transmitter encoder.
The range from such a system can be up to 50 metres Line of Sight (LOS). The current consumption is
1.5mA however this may be reduced to only 1 – 2 uA by placing the device into sleep mode and turning off
the supply to the radio section. A supervisory processor can then wake the module from time to time to allow
it to check for the presence of radio data.
Custom versions of this product are available, please contact our sales department for further details

Learning a New Transmitter Encoder (Applies to all Decoders)
1. Briefly press the programming switch (PSW).
2. Learn LED will illuminate.
3. Depress the transmitter once, Learn LED will extinguish.
4. Depress the transmitter again, Learn LED will flash. (approx 10secs).
5. Wait for Learn LED to stop flashing.
6. This transmitter will now operate the system.
Erasing The Memory – all modules
1. Press and hold PSW for 10 seconds.
2. Release PSW and LED flashes while the module erases its memory.
Antenna Design
For 99% of applications a 17cm piece of wire is quite adequate for 433 MHz modules ??????. The range
achieved from the system is dependent on the choice and position of the antenna. The space around the
antenna is as important as the antenna itself. The optimum position is to locate the antenna so that is
protrudes directly out the top of the transmitter box. If this is not possible due to other design constraints,
try to keep the antenna, and in particular, the ‘HOT’ end away from other metal in the system such as
transformers, batteries and PCB tracks, especially ground planes.
For further information on Antenna design please see our full product catalogue.
Serial Data Output
Both the HiRK and HiR6 decoders provide a serial data output. (selectable option on HiRK) This outputs
the serial number, button and battery status of the transmitter encoder it has successfully received. It also
gives an indication of which inputs of the encoder have been activated and the status of the encoder
battery. This data has an idle state of logic ‘1’ and may be fed via an RS232 type driver circuit (e.g.
MAX232) which may then connect directly to a PC serial port. (An RS232 level serial data output is
provided on SA123 & RFEVAL2).
Serial data is output continually whilst data is being received from the transmitter. i.e. this output is valid
regardless of whether the encoder has been learnt to the decoder or not. If the user requires the serial
number of pre-learnt encoders only, then the serial output should be configured only to output data when
one of the digital outputs from the decoder is asserted which occurs only when an encoder has been pre-
learnt.)
The data received by the decoder (from the encoder) is checked for correct Manchester coding (it is not
KeeLoq decrypted) and the following data is output from the Serial Data output pin.
The 7 digit KeeLoq serial number.
The KeeLoq button data and transmitter battery state.
A carriage return character and a line feed character.
Please note that older versions of the HIRK used a different data format of 57.6K 7 Data Bits and 1 stop
bit, these modules will be prefixed with AR4 on the end of the part number or below. These modules may
still be ordered but we would highly recommend that the new HIRK modules (AR5 and above) are
incorporated into new products.

HIRK-315
HIRK-433
RF RECEIVER DECODER HYBRID. HIR6-433
Serial Data Format
Serial Data is sent as a stream of ASCII characters at 9.6K baud. The character format is 8 data bits
with 1 stop bit, no parity.
A serial data string is output every time a valid transmitter packet is received. Due to the nature of
the KeeLoq packet there will be a minimum gap between each serial data string of 150mSec.
10 characters are sent with the following format;
The Transmitter Serial Number : is made up of 7 ASCII characters from the following group: 0 1 2
3 4 5 6 7 8 9 A B C D E F. The most significant serial number digit is transmitted first. This provides
a total of 28million possible serial numbers.
The KeeLoq Button Status is transmitted as an ASCII character in the range A to O or if the low battery
bit is asserted (encoder battery is low) then in the range a to o. KeeLoq data bits S0, S1, S2 and S3 then
make up the ASCII byte least significant bits D0, D1, D2 and D3.
If a single encoder button is pressed, say S0, then character A will be sent (or if low battery, a).
If encoder button S1 is pressed then B (or b) will be sent.
If S0 and S1 are both pressed simultaneously then character C (or c) will be sent.
If all KeeLoq encoder buttons are simultaneously pressed then character O (or o) will be sent.
Examination of the ASCII bit patterns shows that this allows single or multiple encoder button presses to
be decoded by the ASCII receiving device.
Examples of Serial Data output:
For a three button keyfob with serial number 2345678, the serial data output when encoder transmission is
decoded would be as follows:
If S1 is pressed: 2345678A (2345678a if the battery voltage in the transmitter is low)
If S2 is pressed: 2345678B (2345678b if the battery voltage in the transmitter is low)
If S1 and S2 are pressed together: 2345678C (2345678c if the battery voltage in the transmitter is low)
If S4 is pressed: 2345678H (2345678h if the battery voltage in the transmitter is low)
