Phone Tones Generation (DTMF)
The EasyVR module is also capable of generating DTMF sounds. This feature can be tested by using the
“Dial Tones” command in the “Tools” menu.

The tone duration can be specified in increments of 40 ms (milliseconds). The dial tone has a fixed duration
of 3 seconds (its duration can be modified when programming the EasyVR).
Testing SonicNet
TM
Another feature available from the “Tools” menu is the “SonicNet”, a wireless communication protocol based
on transmission and detection of special sequences of tones, called “tokens”.
Two kinds of tokens can be selected: a short version, with up to 16 different tokens, and a long version that
provides up to 256 tokens.

The EasyVR module can listen for incoming tokens continuously, or for as long as about 28 seconds
