LP-X24 and LP-X48 Users Manual
At the bottom of the Setup Mode screen you see the Contrast Control. Adjust the
display contrast using the center wheel.
In this chapter we discuss the features of Setup Mode that are essential to operating the
LP-X. The remaining Setup Mode features are discussed in "Chapter Twelve: Other
Setup Features" beginning on page 191.
The Instrument Menu
The Instrument menu provides functionality to add, edit and delete moving lights within
the system.
DMX Line Assignment
Before controlling instruments with the LP-X, you must configure the system with the
correct numbers and types of instruments. DMX line assignment locates a moving light
instrument at a specific DMX address.
The LP-X24 drives one DMX line with 512 channels. By default, the first 100 DMX
channels are reserved for conventional lights
a setting that can be changed if desired.
The LP-X48 drives two DMX lines with 512 channels each. By default, the first 200 DMX
channels on Line A are reserved for conventional lights
a setting that can be changed
if desired.
Different moving light instruments require different numbers of channels. For example,
the Martin 218 requires nine channels whereas the Cyberlight requires twenty channels.
The number of attributes that an instrument has usually determines the number of
channels it requires. In rare instances, two attributes are assigned to the same channel,
with one attribute responding to DMX values of 1 to 128 and the second attribute
responding to DMX values of 129 to 255. These are called "split attributes".
If you were to assign a start address of 101 to the Cyberlight, the next available start
address would be 121. If you were to assign a start address of 101 to the Martin 218, the
next available start address would be 110.
To help manage large systems, the LP-X maintains a list of the instruments that you
assign to your system. The LP-X assists you in making DMX line assignments by
keeping track of the number of channels required for each instrument and by suggesting
start addresses that will accommodate the requirements of new instruments as you add
them. As equipment is added, the LP-X will help you find available space for additional
addresses required.
Some instruments can only be assigned to specific channels. For example, the
Cyberlight can only function if assigned to channel 1, 21, 41, 61 and so forth. Consult
the manufacturer’s literature to determine if such restrictions are relevant to your
instruments.
