1) Introduction
The new ULD series dimmer is designed to be a capable and reliable solution for
temporary and portable dimming requirements. With the menu-based interface, the
dimmer can be configured for different applications, including stand-alone use
without a controller. Default values can be restored at any time, clearing the internal
memory back to the standard values.
Please take a few minutes to review the specifications and operating features of the
ULD-360 dimmer.
The ULD-360 dimmer is designed for use with conventional incandescent fixtures.
Transformer loads, such as low voltage devices using a step-down transformer, may
require an additional load to be connected to the same circuit to operate properly.
For operating florescent fixtures, see the section regarding Front Panel Controls.
2) Specifications
Power Connection
Unless otherwise indicated, your ULD-360 dimmer is designed for connection to
standard US power systems, 120 VAC 60 Hz. Lamp connections must be 120 V
devices only. Line voltages over 135 VAC will trigger theovervoltage protection
circuit and shut off the dimmer pack.
Ambient Temperature
The ULD-360 dimmer is designed for use in a cool, ventilated area. Ambient
air temperature must be less than 40 degrees Celsius, or about 104 degrees
Fahrenheit.
Power Capacity
The ULD-360 DMX is unique in the market of small portable dimmers. A single
breaker is used on the pack instead of individual fuses per each channel. As a
result, the limits of the dimmer arepack limits, not channel limits. The following
guidelines should be followed:
ULD-360 DMX
Pack Limit: 15 Amps
ULD-360 DMX-HP
Pack Limit: 15 Amps per line cord, or 30 amps total

- 5-
Control input
The ULD-360 DMX accepts DMX 512 1990 as specified by USITT. Reliable DMX
systems require cable rated for data communication at 250K baud; for this reason the
use of microphone cable is NOT recommended. DMX rated cables are available pre-
manufactured from your Leprecon dealer. For more information on the DMX standard
and acceptable cable, see the Appendix at the end of this manual.
For convenience, DMX in and out connectors are provided on the ULD-360DMX. This
allows easy connection to additional dimmer packs. The DMX standard allows up to 32
dimmers to be connected to a single DMX controller.
For proper operation, it is recommended that the last dimmer in the system have a
termination plug placed in the DMX Out connector. Termination plugs can be purchased,
or easily built by installing a 120 ohm resistor between pins 2 and 3 of the 5 pin XLR.

3) Optional Wireless DMX
All Leprecon ULD models are available with wireless DMX capability. This system has
been developed by Wireless Solutions, and offers increased flexibility and convenience
for setting up a DMX system. Leprecon w-DMX dimmers will be compatible with other
W-DMX equipment that uses components from Wireless Systems.
When a ULD-360 is used in a wireless system, it converts the wireless signal to a
conventional DMX signal. The DMX output of the wireless dimmer can be used to drive
other conventional DMX receivers, such as other ULD dimmers that do not have wireless
capability.
So, in a wireless system, one dimmer can be used to receive the signal from the
transmitter, and connect with DMX cable to up to 32 other standard DMX devices.
W-DMX dimmers are identical to the standard ULD models, with these additions:
•Internal receiver card and power supply
•External antenna
•Switch and LED indicator for setting the communication link.
Background Information
The W-DMX system uses a 2.4 ghz radio signal to transmit DMX data. Spread-spectrum
transmission (AFHSS) technology prevents interference with the DMX signal from other
radio devices.
Range for the W-DMX is approximately 2300 feet using the standard antenna with a clear
line-of-sight. The signal will penetrate walls and other barriers, but the signal level will be
reduced. Human bodies will block the signal, so it is best to locate the transmitter and
receiver above audience areas.
W-DMX Link
The ULD dimmer is designed to receive data from any of the W-DMX transmitters. A
system is complete when the receiver is 'linked' to a specific transmitter. Establishing
this 'link' allows many receivers to be controlled by a single transmitter, and also allows
multiple transmitters to be used in the same area, each controlling specificreceivers.
The ULD dimmer endplate has two controls for setting up the W-DMX link.

- 7-
The LED located on the dimmer endplate shows the status of the wireless link.
?OFF – Dimmer is not linked to any transmitter. DMX cable input can be used.
?ON – Dimmer is linked to a transmitter, and receiving DMX data.
?ON, short blink off – Dimmer is linked to a transmitter, but no data is being
received.
?On / Off flash – Dimmer was linked, but connection was lost.
The push button switch next to the LED is used to unlink the receiver from the
transmitter. To do this, press the switch, and hold it down for four seconds. The LED
will turn off, indicating that the link has been broken.
To establish a link to a specific transmitter:
1) Unlink the dimmer by pressing and holding the switch as described above.
Verify that the LED is off.
2) Press the function switch on the TRANSMITTER for one second.
The dimmer LED should light to indicate that it is now linked to the transmitter.
To unlink ALL dimmers from the transmitter:
1) Press and hold the function switch on the TRANSMITTER for four seconds.
The status LED’s of all dimmers previously linked to that transmitter will turn off.
More information can be found in the manual for the specific W-DMX transmitter that you
have in the system.

3) Installation
Mounting
The ULD-360 is designed for vertical mounting. The top hanging bracket has a pre-
punched hole for a standard ½” pipe clamp mounting bolt. Using this mounting point
allows the dimmer to be mounted with the power cords, DMX display and DMX control
connectors facing downward.
The ULD-360 dimmers are passively cooled, using no internal fans. The heat generated
by the dimmer is dissipated by the extruded metal chassis, and the airflow through the
chassis vents. For this reason, mount the dimmer so that air is free to circulate around
the dimmer. The dimmer should be mounted with at least 12 inches of clearance
between the dimmer and any ceiling or obstruction above the dimmer that would block air
circulation.
Power Connection
Leprecon LD360 series dimmers are supplied with line cords which have standard
Edison plugs attached. Each line of the LD360 should be connected to a service capable
of supplying 15 amps and protected by a properly sized circuit breaker.
If you have any questions about the suitability of the power circuit that you intend to use
with the LD360 dimmer, consult with a qualified electrician.
Load Connection
The LD360 DMX dimmer is offered in several different models. Options include stage pin,
Nema 5-15 duplex, and Nema L5-20. Lamp loads are plugged directly into the outlets on
the body of the dimmer.
4) Turning on Power
The ULD-360 has one line cord and circuit breaker, and the ULD-360HP has two of each,
as illustrated previously. On the HP model, the line cord and breaker to the left on the
endplate, labeled ‘A’, supplies power for channels 1-3, as well as the internal power
supply for the control electronics. Line cord and breaker ‘B’ supplies power to channels 3
through 6.
Power applied to the dimmer is signaled by an internal green indicator in each of the
breakers. If the breaker is on, but not lighted, there is no power to the line cord. Turning
on breaker ‘A’ will also light the red LED display.
Note:
The unit can be Reset to original factory settings by depressing and holding the
ENTER switch while turning on the first breaker.

5) Front Panel Controls
The ULD-360 dimmer uses a 4 digit display and four entry switches to set pack
functions, and display operating status.
Resetting the ULD-360 to default values:
The unit can be Reset to original factory settings by depressing and holding the ENTER
switch while turning on the first breaker.
Address Menu
When the dimmer is first turned on, the display shows the starting channel address of
the ULD-360. This is the DMX address that will control the first channel of the pack.
When there is no DMX input, the channel number is preceded by the letter A for address:
When valid DMX is detected, the letter ‘A’ is replaced with the letter ‘d’ for DMX:
.
004 A
.
d 004

- 10 -
The UP/DOWN keys change the value for the start address. The ULD-360 uses the
changed value immediately and permanently saves it after 10 seconds or if the Enter or
Menu key is pressed.
After power on, the ULD-360 remains in the Address Menu in its simple interface mode.
To go to any other menu requires the user to hold the MENU key for about 5 seconds.
Setting Start Address
The default start address for the ULD dimmer is 001. That means the first dimmer circuit
will respond to the first DMX channel from the controller. If the controller is set to a
‘normal’ patch, dimmer circuit1 will respond to control channel 1, dimmer circuit 2 will
respond to control channel 2, and so on for all of the circuits in the pack.
If you have multiple ULD dimmers, generally the first dimmer will be set to start address
001. Assuming that each dimmer has six circuits, the start address for the second pack
would be 007. This sets up each dimmer with independent control for each dimmer
circuit.
Channel Mode Menu
The Channel Mode Menu allows setting the mode of each dimmer channel.
This mode is indicated by the letter ‘c’ in the display:
Set the mode for the displayed channel by pressing the UP/DOWN keys. The possible
channel modes are:
Mode Description
Ln Linear output. Standard dimmer channel.
Nd Non- dim. Fader input above 60% turns on channel to 100%. Input
below 40% turns off channel.
FL Florescent output. Dimmer does not begin to turn on until 20%.
00-FF Fixed output level. Values are 0, 10-99 and FF. FF is 100% output.
