1. SYSTEM OVERVIEW
The transmitter key consists of the fork (fork-shaped plastic component
with a steel shank and the slide-in module with a hole for the key ring, and
three buttons). The shank location is described below as "front", and the
side of the slide-in module which contains the buttons, is described as
"top". The key ring hole is thus located on the back on the left.
General functions of the buttons
Whenever a button is actuated, a telegram is emitted containing the
information as to which button has been actuated. Two successive button
actuations are only recognized if they are effected with an interval of at
least 65 ms. However, each button actuation gives rise to at least four
successive telegrams, even if another button is being actuated while they
are emitted. If the button is not released, max. 50 identical telegrams are
emitted. If the button is released after more than 4 telegrams have been
emitted, the telegram being generated is emitted, then the function is
aborted. Each new button actuation results in a new computation of the
alternate code, and in a new telegram sequence being sent. The control
unit receives the various telegrams generated by button actuation, and is
capable of distinguishing, via the alternate code, between continued
actuation and several separate, successive actuations of the button.
