6.2.2 Control – DMX 512 & manual on / off:
If controlled with DMX, the machine uses one channel only, and reads all channels between
001 and 512. The machine is ON at DMX level 77 (approx. 30%). XLR pinout:
Pin 1 = gnd / sleeve, pin 2 = signal - , pin 3 = signal +
ON / OFF can be controlled with DMX or manually.
There are only two ways to control an Ultimate 2000 DMX:
1. Manually by pressing OK button for ON, press again for OFF, or:
2. via DMX 512.
Control with DMX signal only:
•
Connect a DMX cable to the male XLR connector. The DMX cable is linked to a standard
DMX 512 source (e.g. a light desk).
•
Set mains switch to “1”.
The display indicates the last stored address, or “OFF” if the last
operation mode was manual.
•
Select a DMX address between 001 and 512 (the machine uses one channel only): Use
the up/down keys to select address (the display flashes while the new address is being
selected).
Tip: Press and hold “up” or “down” key for faster count.
•
Press “OK” to store the selected address.
The display will now stop flashing, to confirm the
address is stored.
•
When the level of the selected DMX address is 77 or more, the machine is on. When the
level is 76 or less, the machine is off. The red “operation” LED indicates the machine is
switched on by the DMX electronics.
•
If the DMX source is manually controlled with potentiometers make sure the potentiometer
is not adjusted only around level 77. It can make the machine go on and off repeatedly.
The output cannot be controlled with the DMX level, only through the operating
intervals.
The best way to control the machine without the risk of an unwanted start or stop (and risk
of damage to compressor motor), is to set the level at 0 (0%) for off, and 255 (100%) for
on.
Tip: The last selected address will be stored in the processor´s memory when the machine is
switched off and/or mains voltage is disconnected. The address is set as default next time the
machine is switched on.
In an application where the machine is used with the same address every time (e.g. on tour or
in permanent installations), it is not necessary programme again at power on, as the last
selected address is pre-set as default.
If, for any reason, a different address is to be used temporarily: Set the temporary address,
but do NOT press “OK” (the temporary address will flash in the display). The machine will
respond to the temporary address until mains power is switched off. Next time it is switched
on, the usual, favourite address will be set as default.
Manual control without DMX:
•
Select an address below 1 or above 512 (the display indicates “OFF”).
•
Press “OK” button to start and stop (the display indicates “On”. The red “operation” LED
indicates the machine is on.
Remote control from external power sources:
Ultimate 2000 DMX cannot be controlled from external switch or relay units. Use the
integrated DMX control, connected to a DMX light desk, or manual control only. When
used in “manual” mode; for safety reasons, electronics will always start up in “OFF”
mode if mains supply is disconnected and re-connected again. Machine will not start
automatically, “OK” button must be pressed.
