ds000011 rev2.3 july ?99 1999 reg no 277 4001, england. page 5 m iniature rf r eceiver d ecoder m odules . ?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. learning a new transmitter 1. hold down the programming switch (psw1). 2. depress the transmitter once, led on the decoder will flash. (psw1 is still depressed). 3. wait for led to stop flashing. 4. depress the transmitter again, led will turn off. (psw1 is still depressed). 5. release the programming switch (psw1). 6. this transmitter will now operate the system. 7. 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
