DMX-IT 12 SETUP and OPERATION
dmx-IT
models are
really
simple to use.
For many applications, just set it to “1” and go to work!
Model
dmx-IT
12
lighting console provides
dimming control over any 12 consecutive
channels of standard DMX512 receivers.
The
MASTER
fader controls the maximum output
level for fader channels
1-12
.
The
CHANNEL
section has sliders
1-12
that set
the level of an individual DMX channel.
DMX CHANNEL SELECTION for FADER
CHANNELS 1-12
The starting address of the
dmx-IT
12
can be any
channel in the DMX512 address space. If the
starting address is set to 25 then DMX receivers
set to 25 through 36 will respond to the channel
sliders
1-12
.
To change the starting address of the sliders
1-12,
set the DIP switches on the rear to ON so that the
numbers:
1 2 4 8 16 32 64 128 256
add up to the starting channel you want.
Push down (toward the numbers) to turn them ON.
DO NOT USE A PENCIL, THE ‘LEAD’ IS
CONDUCTIVE.
YOU MUST TURN THE POWER OFF FOR SEVERAL
SECONDS, THEN BACK ON BEFORE THE NEW
SETTINGS TAKE EFFECT.
POWER
The
dmx-
IT operates on 4AA batteries or the
supplied AC adapter.
The
POWER
LED indicates power is present
when the power switch is turned on. If using
batteries, the LED will flash when the battery
voltage is low. If the batteries are too low to
operate, the LED will turn off and the
dmx-IT
will stop transmitting.
To conserve battery power the
dmx-IT
stops
transmitting when the Master slider is at 0.
NiCad or NiMH batteries are not recommended
as operating life will not be acceptable due to
their lower initial cell voltage.
Expected battery life for alkaline batteries is 20-
30 hours of operation
Replace the 4 AA batteries (not included) in the
slide out tray by loosening the screw at the
bottom front of the enclosure and sliding out the
battery tray. It is not necessary to remove the
screw completely, just loosen it enough to re-
lease the battery tray.

The starting channel assign switches are read
during the power up cycle of the
dmx-IT
12
.
Changing the switch settings with power on will
have no effect until the power is cycled off, then
on again.
CHANNEL SETTING RANGE
Available starting addresses for the
dmx-IT
12
are from 001 to 511. With no value set on the
address switches (all switches off/up), the unit
will assume starting channel of 1. Setting the
starting address to a channel number from 502
to 511 will result in the sliders controlling the
channels from the starting address up to chan-
nel 512. The remaining sliders will be ignored.
For example, with the starting address set to
511, channel sliders 1 & 2 will control channels
511 & 512. Sliders 3-12 will be ignored
.
