GENERAL DESCRIPTION
The SM-280 is a fixture (or scanner) oriented DMX
controller. It can control up to 14 fixtures of 20 DMX
channels each. The unit can also be used to control
conventional dimmer packs. The SM-280 includes 14
scene banks. Each bank can contain up to 22 scenes.
There are also 14 programmable chases. Each chase
may contain up to 255 steps. Scene banks can be
automatically run like chases.
Each fixture is permanently assigned a block of DMX
addresses. The table below shows the assignments.
Fixture # Channels
1 1-20
2 21-40
3 41-60
4 61-80
5 81-100
6 101-120
7 121-140
8 141-160
9 161-180
10 181-200
11 201-220
12 221-240
13 241-260
14 261-280
The fixtures must be set to accommodate these DMX
assignments. This is usually done using DIP switches
on the fixture to set its starting address. Refer to the
fixture manual for exact instructions. The information
is sometimes shown on a tag or chart on the fixture. If
you set multiple fixtures to the same addresses then
they will controlled together.
FIXTURE FUNCTIONS
You will need to know which channel within a fixture
is assigned to each fixture function (Pan, Tilt, Color,
Dimming, etc.). This information is contained in the
fixture manual.
DMX CONNECTIONS
Any system using DMX control should be connected
together as a chain of devices. The control cable
should proceed from the controller to the first fixture
and then on to other fixtures in a continuous "daisy
chain" fashion. Most fixtures have a DMX IN and a
DMX OUT connector to be used to connect the chain.
The control cable should NOT be split into a multiple
run star arrangement with a cable running from the
controller directly to each fixture.
DMX CONNECTOR PIN ASSIGNMENTS
There are two different connectors which can be used
for DMX control. They are both XLR connectors.
Some units use 3 pin connectors. Others use 5 pin
connectors. The SM-280 transmits DMX from a 3 pin
female connector on the back edge of the unit. If your
fixtures use 5 pin connectors then you can make up an
adapter cable to accommodate this. The table below
shows the pin assignments.
PIN # SIGNAL NAME
1 DMX COMMON
2 DMX DATA 3 DMX DATA +
4 NOT USED
5 NOT USED
Some fixtures use a reversed signal assignment. In
this case the DATA - and DATA + pins are reversed.
The SM-280 has a reversing switch on the back edge
to accommodate this situation.
DMX TERMINATION
A DMX chain should be terminated at the last fixture
(and ONLY the last fixture) on the chain. This is
done by installing a commonly available 1/4 Watt,
120 Ohm resistor across the DATA - and DATA +
wires at the last fixture. If you have only a few
fixtures close together and a very short run to the
controller then you may be able to operate without the
terminator.

You cannot store a scene beyond the next available
scene in a bank. For instance: If the bank has 4 scenes
in it and you try to program scene 7 then your scene
will be recorded but it will appear in scene 5.
EDIT A SCENE
You can edit the settings of one or more of the fixtures
in a scene without re-recording all the fixture settings.
This process does not apply to the last scene in the
bank. If you edit the last scene the results will be a
new scene.
The process is done in Program mode and is almost
the same as in described in ADD
. When you select the scene it will activate the

pushing a SCANNER/SCENES button (1-14).
2. Push Scene and select the scene which will become
the new scene by pushing a SCANNER/SCENES
button (1-22). For example: If you want to insert a
scene between scenes 2 and 3 you would select
scene 3. In other words the new scene will be
inserted before existing scene 3.
3. Push Auto/Insert.
4. At this point the process is the same as for
RECORD A SCENE. Select and set up the
fixtures as desired.
5. When all fixtures are set - Push Program/Record to
store the inserted scene. The controller indicators
will flash briefly.
DELETE A SCENE
1. Push Bank and select the bank containing the scene
by pushing a SCANNER/SCENES button (1-14).

EXTERNAL MEMORY CARD
The SM-280 is supplied with a 4 MB external
memory card which can be used to automatically
record scene and chase program data. When a card is
installed, the Memory Select button can switch the
controller between its internal memory or the external
card. Controller/Fixture initial setup data is always
from internal memory.
External memory card operation is active when the
RED indicator on the Memory Select button is ON.
The card is a special purpose device intended ONLY
for use with the SM-280 controller. It cannot be used
with other devices.
If you install and activate the card when programming
scenes and chases then that information will be saved
to the card. If the card is active when you operate the
unit then the scene and chase data will come from the
card instead of the internal memory.
FOG MACHINE CONTROL
The rear panel of the SM-280 has a IEC connector for
remote control of certain fog machines. It looks like
a computer power cable connector.
DO NOT PLUG THIS CONNECTOR INTO A POWER
SOCKET OR APPLY AC LINE POWER TO IT.
The controller will be damaged if this is done.
If properly connected to a compatible fog machine
then the indicator on the controller FOG MACHINE
button will light when the fog machine is ready to use.
The FOG MACHINE button can be used to activate
the machine.
