DMX Wiring Configurations
Depending on the size of the installation, there are several configurations that will ensure that
each fixture receives a clear signal.
INSTALLATIONS WITH LESS THAN 32 FIXTURES
For installations under 32 fixtures and installations less than 1,200 meters (3,900 feet) in cable
length, the signal can be daisy chained in series from one unit to the next using either Cat-5e
cable or XLR cables.
LARGER INSTALLATIONS OR LONG DISTANCE
Installations requiring more than 32 fixtures or installations spanning cable lengths greater than
1,200 meters (3,900 feet) will need to use a DMX amplifier. Due to the limitations of the RS-485
protocol, this is needed to ensure that each string of 32 fixtures receives sufficient signal strength.
DATA TERMINATION
It is always recommended to terminate DMX daisy chains with a resistor of the same
characteristic impedance as the cable (typically 100-120 Ohms). To terminate a DMX daisy chain,
place the resistor across Data pin (+) and Data pin (-), which are specified in Table 3.
