8.8 CONTROLING OUTPUTS WITH DTMF
GSW2 PLUS can control the outputs with the use of DTMF. This is very useful function in the
intercom application.
To control the outputs the user must press the combination of 2 digits. First digit is used to select
the output (1 to 2), the second digit is used to activate (1) or deactivate (0) the output. There is a
special case when the user can select for first digit (output selection) number 0. In this case all
outputs control by the same time.
Combination must be pressed in 2s interval, and must be 3s apart to be valid.
