3User Manual
Thank you for selecting the Martin DMX Switch Pack. This DMX-controlled switching
device allows you to turn on and off up to six 350 watt devices with the Martin 2518 DMX
Controller or any other DMX board. It allows you to control non-intelligent lights; it is
ideal for combining fixtures from Martin’s DJ Series with intelligent lights.
The DMX Switch Pack is ruggedly built for years of trouble-free use. Setup and operation
are simple; please read this manual before setting up and operating the device.
Safety information
WARNING!
This product presents risks of lethal or severe injury.
This product is for professional use only. It is not for household use. Read this manual
before powering or installing the fixture, follow the safety precautions listed below and
observe all warnings in this manual and printed on the fixture. If you have questions about
how to operate the fixture safely, please contact your Martin dealer or call the Martin 24-
hour service hotline at [phone].
To protect yourself and others from electric shock
• Disconnect the fixture from AC power before removing or installing fuses or any part,
and when not in use.
• Always ground (earth) the fixture electrically.
• Use only a source of AC power that complies with local building and electrical codes
and has both overload and ground-fault protection.
• Do not expose the fixture to rain or moisture.
• Refer all service to a qualified technician.
• Never operate the fixture with missing or damaged covers.
To protect yourself and others from burns and fire
• Never use the device to power fixtures that exceed the specified maximum load.
• Never attempt to bypass the fuses.
• Always replace defective fuses with ones of the specified type and rating.
• Do not modify the fixture or install other than genuine Martin parts.
To protect yourself and others from injury due to falls
• When suspending the fixture above ground level, verify that the structure can hold at
least 10 times the weight of all installed devices.
• Secure the device with a safety wire threaded through the side holes.
• Block access below the work area whenever installing or removing the fixture.

4 DMX Switch Pack
Setup
The DMX Switch Pack comes with a 5 meter shielded 3-pin XLR cable. In addition, the EU
version includes 6 standard male IEC plugs for connecting fixtures.
The following installation steps are required:
1. Install a plug on the power cord
2. Install IEC plugs on the fixtures (EU version only)
3. Connect the data link
4. Set the DMX address
Install plug
The switch pack is delivered with no plug on the power cord. Following the manufacturer’s
instructions, install an approved 3-prong grounding-type plug that fits your supply. Connect
the wires to the pins as listed below. The table shows some possible pin identification
schemes; if the pins are not clearly identified, or if you have any doubts about proper instal-
lation, consult a qualified electrician.
Connect data link
Connect the data link cable to the “In” jack using a 3-pin female XLR connector. If using 5-
pin cables, a 5-pin male to 3-pin female cable such as Martin P/N 309160 must be used.
(Pins 4 and 5 are not used.)
Continue the data link by connecting the cable to the “Out” jack; use a 3-pin XLR male
connector. Insert a termination plug in the “Out” jack if the switch pack is the last device on
the link. A termination plug is simply a 3-pin male XLR connector with a 120 ohm resistor
soldered between pins 2 and 3.
Connect fixtures, EU version
IEC male plugs, included, must be installed on the fixture power cords. Connect the wires
as shown in the above table. Consult a qualified electrician if the power cord for your fix-
tures are colored differently.
Plug the fixtures into the power outputs. Each outlet can deliver up to 350 watts of power.
Do not connect higher wattage devices to the switch pack or connect more than one fixture

to an output.
Connect fixtures, US version
Plug the fixtures into the power outputs. Each outlet can deliver up to 350 watts of power.
Do not connect higher wattage devices to the switch pack or connect more than one fixture
to an output.
Set DMX address
The DIP-switch must be set to the start channel, also known as the address, which is the
first of the six channels the controller uses to send instructions to the switch pack. Any
channel between 1 and 512 may be selected as long as the last channel (6) is within the con-
troller’s range. The 2518 DMX Controller has 72 channels; the highest useful start channel
is 67.
Set the DIP-switch by switching ON one or more of the pins until their total value equals
the start channel. Each ON pin adds the value listed below; OFF pins add no value.
The setting can be found by subtracting pin values, starting from the highest value that is
less than or equal to the start channel, until the total of the values subtracted equals the
channel number. See the examples below.

6 DMX Switch Pack
Operation
Apply power
The panel diode lights when power is applied to the DMX Switch Pack.
Control fixtures
Power output 1 is controlled on the first channel, power output 2 is controlled on the second
channel, and so on. To turn a fixture on, set the channel’s DMX value anywhere above 50
percent (DMX 128 - 255). To turn it off, set the value anywhere below 50 percent (DMX 0
- 127).
Maintenance
Replace fuses
If the power diode does not light when power is applied, the main fuse may be blown. The
main fuse is found in a holder next to the power cord; it can be replaced without opening the
cover.
Each power output is fused as well. If one channel does not function properly, the power
output fuse may be blown. The cover must be removed from the unit to access these fuses.
Always disconnect the switch pack from electricity before servicing.
If a fuse blows repeatedly, there is a malfunction with either the switch pack or one of the
fixtures connected to it that must be referred to a service technician. Always replace the fuse
with one of the same size and rating.
