6 USER SWITCH
This section refers to the 3.5mm / 1/8” jack sockets on the Omni2 Input Section. See the connections diagram in Chapter 1 for
further details.
If the Omni2 is configured for a normally-closed User Switch, there should be a permanent low signal and a high signal will be
interpreted as a switch operation. If the Omni2 is configured for a normally-open User Switch, the opposite will apply.
6.1 SIGNAL LEVELS
Low signal < 0.8V.
High signal > 4.0V.
Impedance: 10K to 5V.
7 ON/OFF SWITCH
This section refers to the 3.5mm / 1/8” jack sockets on the Omni2 Input Section. See the connections diagram in Chapter 1 for
further details.
A normally-open switch should be connected. A low signal is interpreted as a switch transition and will switch the Omni2 on or
off.
7.1 SIGNAL LEVELS
Low signal < 0.8V.
High signal > 4.0V.
Impedance: 10K to 5V.
8 SIP AND PUFF INPUT
This section refers to the pneumatic inlet on the underside of the Omni2 Input Section. See the connections diagram in
Chapter 1 for further details.
Approximate pressure levels for full hard sips and puffs are:
Full puff 1PSI or 69mbar.
Full sip -1.2PSI or –83mbar.
