 LCN requires the use of
a standard tap-action switch. The advantage of using tap-action
switches - as opposed to toggle switches - is the variety in
press modes. Some of the following pressing modes are recognized by LCN:
Each button can therefore
store 3 different functions. In other words, 3 different commands
can be triggered by pressing the buttons accordingly.
This button-function-matrix illustrates the possible combinations
of
button numbers and the press mode.
Since only
one receiver ID can be programmed per button, a so-called shadow-function-table
is added. That makes life easier because the commands in both
tables are transmitted at the same time. With this feature, two
receiver IDs can now be
programmed using the shadow-function-table.
For example: If button #3 is pressed, physically or virtually
(per software), the respective commands stored in functiontable
A and shadow-function-table A´ are transmitted
simultaneously.
Additionally, there are two modes of operation: Single mode and Dual mode which will be described next.
