Dmx Operation - JEM Glaciator X-Stream User Manual

HEAVY FOG GLACIATOR

DMX OPERATION

The machine may be operated using the industry standard DMX 512 digital
control protocol. This allows the control of the fog system to be easily
integrated with the lighting system in most installations.
DMX may be used without changing any of the settings on the main control
panel. When the system detects a valid DMX data stream on the input, the
control will default to the DMX system levels. Any attempts to control the
machine from the control panel will have no effect until the DMX signal is
removed. The displays will show the current input values for Fog and
Density.
To ensure correct operation of the displays, the standby switch should be set
to the ON position when using DMX.
The machine requires two channels, with the address of the first channel set
on the DIP switch. The channels control the FOG and Density settings in the
following manner.
Channel 1
FOG output level
0 - 32 zero output (dead-band)
33 - 255 proportional output level control
Implemented in 20 discrete steps
Channel 2
Compressor switching and Density setting
0 - 32 Compressor off
33 - 65 Low (Lo) density
66 - 98 Normal (Nor) density
99 - High (Hi) density
The system implements true proportional control of the fog output rather than
the simple switching functions found on other equipment. The output levels
of FOG and FAN are linked during DMX operation via the Density setting.
The DMX base address can be set to any channel in the range 1 - 511 using
the DIP switches. The channel number must first be decoded into binary
format before being set into the switches.

ICE: Setting this switch to ON, will start the compressor. There will always be
a delay of up to 20 seconds to allow pressure equalisation.
This function is independent of the status of the STANDBY switch.
THE TIMER
The timer system is implemented in software using the machine's main
control PCB. As such, the timing is crystal controlled and will be of good
accuracy when compared to the usual analogue timers commonly found on
fog machines. The timer is enabled by setting the Timer switch on the control
panel to ON.
Pressing the Timer switch will cause the timer to start from the beginning of
the ON period and run through to the end of the OFF period, the cycle will
then repeat until the Timer switch is set to OFF. The timer will only function
when the Standby switch is set to ON and the machine is ready (RdY).
Switching the Timer to OFF at any time during the cycle will halt the
operation.
While the timer is running, the left-hand display will show the elapsed time in
seconds. The display will alternate between the period name (ton/toF) and
the elapsed time in seconds.
To set the time periods, use the Menu key on the left-hand display to set the
'ton' menu as current. Press the Enter key to see the current value for the
On Time (ton), and make adjustments using the Up/Down keys. Now press
enter to store the value and use the menu key to select the Off Time (toF)
menu. Adjust the value as for the On Time, and then enable the Timer switch
on the control panel to test the settings.
The current Fog and Density levels will be used by the timer system when in
the ON period.
