† - Unless this fixture is crossloading, the yellow Transmit LED should
never be ON solid. (The Transmit LED will flicker yellow if you have
enabled preset playback and the fixture is set for either fixture number
1 or DMX start channel 1. This is due to preset playback
synchronization, as described in “Synchronizing Preset Playback” on
page 4-9. Try unplugging the fixture, waiting a few minutes, then
plugging it back in. If the Transmit LED continues to be ON, contact

Overview of Controller Operation
In order to coordinate the playback of multiple Technobeam fixtures
from a central location, you need to connect the fixtures to a DMX 512-
compatible controller using XLR data-grade cabling.

What is DMX 512 Protocol?
DMX 512 is an industry-standard protocol for controlling lighting
fixtures and other devices (such as lasers and hazers). Developed by
the United States Institute of Theatre Technology (USITT), DMX 512 is
supported by leading entertainment industry equipment
manufacturers.

DMX 512 (D for digital, MX for multiplex and 512 is the number of
channels per link) is a reliable, efficient and well-understood control
protocol. Its strength lies in its ability to control virtually any mix of
DMX-compatible devices on the same link using a DMX-compatible
controller.

What Kind of Cabling Should You Use?
There are two main types of cabling you can use: microphone cable
and data-grade cable. Although pin-compatible microphone cable is
suitable for small-scale designs, data cable is recommended, especially
for longer cable runs. Data cable is designed to carry a higher-quality
signal with less susceptibility to electromagnetic interference.
and data-grade cable. Although pin-compatible microphone cable is
suitable for small-scale designs, data cable is recommended, especially
for longer cable runs. Data cable is designed to carry a higher-quality
signal with less susceptibility to electromagnetic interference.
The cable you use should have the characteristics listed below:
•
2-conductor twisted pair plus a shield
•
maximum capacitance between conductors - 30 pF/ft.
