RF RECEIVER DECODER HYBRID.
AM-HIRK
Learning a New Transmitter Encoder
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 HiRK Memory
1. Press and hold PSW , Learn LED will illuminate for approximately 10 seconds while the HiRK erases
its memory.
2. When Learn LED has turned off release PSW
3. Memory is now erased
Antenna Design
For 99% of applications a 17cm piece of wire is quite adequate. 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 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
Outputs 1,2, & 3 are digital CMOS/TTL (PIC Micro) with a series 220 Ω protection resistor.
Outputs are all normally Low, active high.
