DESCRIPTION
This range of miniature modules are complete four channel RF Receiver/Decoders that can be configured for
many different, low power, short range telemetry applications.
All modules are plug-in Dual-in-Line (DIL) package, with the same profile as a standard 40pin DIL I/C for easy
pcb mounting. A single relay option is an extended length module (removable) containing a BT/47 type relay.
Supplied as either AM or FM, the module requires connections to the power supply; 5Vdc or 12Vdc (mandatory
for relay version), and data outputs only. An LED indicates data reception.
Each decoder is compatible with one of the RF Solutions Transmitter / Encoders (see page 2). The decoder has
an easy-to-use 'LEARN' facility to allow the decoder to learn up to eight code Hopping or 16 standard
transmitter/encoders.

NOTE
The module is designed to be powered from either 12v or 5v not both!
The 12v supply is necessary for relay operation.
Removal of Relay
If the relay is not required, remove the relay connecting links “CK1” & “CK2” . The pcb may then be carefully
broken, along the score lines between the relay and the rest of the board. Digital output channel 1 is then
driven by an open collector transistor output.

“STANDARD DATA FORMAT” DESCRIPTION (AM-DS0, AM-DS1)
The transmitter/encoders used in a standard system each have a unique signature code (pre-programmed at
manufacture) from one in >16,000,000 combinations. Error checking techniques are also used to ensure data
integrity.
These decoders are capable of learning 16 unique transmitter/Encoder signature codes.
“HOPPING DATA FORMAT” DESCRIPTION (AM-DH0, AM-DH1, FM-DH0, FM-DH1)
The transmitter/encoders used in a Code Hopping system each have a random number signature code, as in
the standard format, and also transmit a unique signature code each time the switch is pressed. The number
of possible codes is >16,000,000 combinations, the same code is never repeated, even if the batteries are
changed.. Error checking techniques are also used to ensure data integrity.
These decoders are capable of learning 8 unique transmitter/Encoder signature codes.

Hold down the programming switch (PSW1).
Depress the transmitter once, LED on the decoder will flash. (PSW1 is still depressed).
Wait for LED to stop flashing.
Depress the transmitter again, LED will turn off. (PSW1 is still depressed).
Release the programming switch (PSW1).
This transmitter will now operate the system.
To completely erase the transmitters, press PSW1 on the decoder five times in succession, LED will
remain on for approximately 5 seconds while the transmitter(s) are being erased.
SYNCHRONISATION (Hopping Models only)
This equipment requires the transmitter and receiver to be synchronised. If the transmitter has been pressed
more than 50 times outside the range of the receiver, the receiver will loose synchronisation with the
transmitter. To re-synchronise:
Press the transmitter key for two seconds within range of the receiver,
Release the key momentarily, and press the key again.
ANTENNA DESIGN
For 99% of applications a 16.5cm piece of wire is quite adequate. The range achieved from the system is
dependant 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 away from
other metal in the system such as transformers, batteries and PCB tracks, especially ground planes. In
particular, the ‘HOT’ end of the antenna should be kept as far away as possible from these.
For further information on Antenna design please see our full product catalogue.
DATA OUTPUTS
Output 1 is used to drive the on-board relay (if fitted), it is an open collector type output.
Outputs 2,3 & 4 are digital CMOS/TTL with a series 220 W protection resistor
The outputs are configured by Link 1 & 2
