left side of the unit, labeled ‘+10’, ‘+20’, ‘+30’, ‘+50’
etc. Addressing is achieved by pushing a combination
adding up to the desired DMX start address. Any block
of ten channels out of the 512 available channels are
accessible using this procedure buttons.
For example, to access channel 256 when starting with
the default ‘+0’, press ‘+50' and ‘+200'. 256 will then be
on fader 6. To access channel 250, again starting from
the default, press '+200', '+30' and '+10'. Channel 250
will now be the 10
th
fader (channel 241 will be the
first
fader).
A chart outlining the buttons used to access any of the
512 available DMX channels is available on page 10.
Press and hold the OFF CLR button for 3 seconds to set
all SC910 DMX values to zero, until a fader is moved.
SETTING FIXED DMX CHANNELS (PARKING)
DMX channels can be assigned a fixed output level or
be “parked” at any value above 1%. When a channel is
assigned a fixed DMX output value the output will
remain at that value in both scene and channel mode and
cannot be overridden by scene recalls or by independent
DMX control. To set a DMX channel to a FIXED
output:
1. Set the fader(s) associated with the DMX channel to
the level(s) desired.
2. Press the REC button for 3-5 seconds until the REC
and LEDs for 1-8 begin to flash.
3. Press the CHAN MOD button (begins to flash) and
press 88.
4. Press CHAN MOD. The CHAN MOD and REC
LEDs are now on solid.
5. Press 3327 (the LEDs will flash acknowledging your
entry).
6. Press REC button to record the change.
To erase a fixed channel output follow the steps above
setting the level for each of the DMX channels to regain
normal operation to a value of 0% on the fader.
It is important to note which channels have been parked
so they can be changed later if needed.
OPERATION WITH ANOTHER DMX CONTROLLER
The SC910 can be connected to a DMX chain with
another DMX controller/console. If a DMX controller
is already transmitting a signal to the input of the SC910,
once the SC910 is placed in CHAN MOD, no changes
from the DMX input will be passed. The SC910 defaults
to transmit ‘last look’ (last known values for all
channels) for seamless integration with a DMX control
console. With no power to the SC910, the DMX signal
will be passed directly to the DMX output connection.
Push the CHAN MOD button once to enable local
operation. The unit will begin sending the DMX values
set by using the faders. Values set in channel mode
previous to the SC910 receiving a DMX signal will not
be retained.
OPERATION WITH REMOTE STATIONS
While in CHAN MOD mode, the SC910 will accept
responses from simple and smart remote operation,
however the actions WILL NOT occur until the SC910
is taken out of CHAN MOD.
SCENE OPERATION
RECORDING SCENES
The SC910 can store scenes created using the SC910’s
DMX control feature or snapshot scenes from a
connected DMX Device. To record scenes from the
SC910 internally, use the steps outlined in the
SETTING CHANNEL LEVELS section of this manual
to set up the desired look and then follow the steps in
this section.
When the SC910 receives a valid DMX512 signal, the
GREEN DMX LED will be solid as outlined in the
DMX CONTROLLER OPERATION section of this
manual. Once the LED is on solid, the SC910 is ready
to start recording scene snapshots. To record or re-
record a scene:
Set any DMX channels to the value you desire to
capture using the SC910 or control console connected to
the SC910. (Verify the SC910 is in CHAN MOD to
create scenes within the SC910.)
