The snow machine controller consists of one fan relay, a pump controller and control interface capable
of receiving a DMX signal or a proprietary remote control signal. The DMX address is set via a three digit
rotary switch located on the back of the device. The DMX address is set in a decimal fashion.
The DMX interface is compliant with DMX-512 standards
and electrically isolated to 1000VAC. The starting address
can be set from 1 to 509. The DMX protocol requires 4
dimmers defined as Mode, Cycle Time, Duration and Flake
Size. The Mode dimmer defines the overall operation of
the snow machine - Off, On, and Momentary. The Mode
dimmer will correspond to the selected start address,
with the Cycle Time, Duration, and Flake Size channels in
the following order.
When the mode channel is set to one of the Momentary
positions (either 5 or 15 min cycle), the Cycle Time and
Duration channels become active. The cycle time channel
establishes the time it takes for the entire event. Duration
channel is the length of time of snow output. The minimum
time of one cycle is 18 seconds with a ten second ON time, a
four second SNEEZE, and a four second WAIT. A sneeze is
when the blower remains on without the pump and dries
the sock, preventing postnasal drip.
Table 1
shows that there are six modes in which
the device may operate: Idle, DMX, 5 minute
cycle, 15 minute cycle, always on, and remote.

The following tables show all the settings that can be attained with the use of the three digit rotary
switch located on the back of the device. An ‘X’ indicates that the number in that position does not
matter for the required result to be attained. Switch A is in the hundreds position, Switch B is in the
tens position, and Switch C is in the ones position.
