The ProMix 2KS Automatic system does not use a
Booth Control. Instead, it uses Discrete I/O or Network
Communications to drive the system. Each method can
be used exclusively, or both at the same time.

the main mode of control, it can be used if proper Gun
Trigger Input is provided.

Discrete I/O
Discrete I/O requires a 24 Vdc power supply which must
be supplied on site. The ProMix 2KS does not supply
power for Discrete I/O.
