(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 achiev ed from the system is dependent on the choice and position of the antenna. the space around t he antenna is as important as the antenna itself. the optimum position is to locate t he antenna so that is protrudes directly out the top of the transmitter box. if this is not possible due to ot her design constraints, try to keep the antenna away from other metal in the system such as transform ers, 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 ? protection resistor. outputs are all normally low, active high. link status transmitter switch 1 2 3 link1 link2 o/p 1 o/p 2 o/p 3 open open latch latch latch open connected mom mom mom connected open mom mom latch connected connected latch latch mom transmitter encoder switch o/p 1 o/p 2 o/p 3 1 switch keyfob centre switch - - 2 switch keyfob lh switch rh switch - 3 switch keyfob lh switch rh switch top switch (red)
