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.
2.
3.
4.
Install plug
The switch pack is delivered with no plug on the power cord. Following the manufacturer’s
instruction s , in stall an approved 3- prong grounding-type p lug that fits your supp ly. Connec t
the wires to the pins as listed below. The table shows some possible pin identification
schemes; if the pin s are n ot cle a rly ide n tified, or if you have any doubts a bo ut pro per in sta llation, 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 5pin cables, a 5-pin male to 3-p in female cable su ch as Martin P/N 30 9160 must be used.
(Pins 4 and 5 are not used.)
Continue the data l ink by connecting the cab le to the “Out” jack; use a 3-pi n 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, i ncluded, mu st be inst alled on the fixture powe r cords. Conn ect the wir es
as shown in the ab ove table. Con sult a quali fied electrici an if the powe r cord for your fi xtures 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 b e set to the start channel , also known as the addres s, 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 controller’s range. The 2518 DM X C on troller 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 example s below.

Operation
Apply power
The panel diode lights when power is applied to the DMX Switch Pack.
Control fixtures
Power output 1 is c ontro lle d on th e first c h ann el, p ower o utp u t 2 is c ontro lle d on th e second
channel, and so on. To turn a fixture on, set the ch annel’s DMX value anywhere abov e 50
percent (DMX 12 8 - 255) . To turn it off, set the va lu e an ywhe re be low 50 perc ent (DM X 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 hold er nex t to the powe r cord; it ca n be replaced withou t opening t he
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 remove d from the unit to access these fuses.
Always disconnect the switch pack from electricity before servicing.
If a fuse blows repeatedl y, there is a malfunction with ei ther the switch pack or one o f 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.
