contains a power indicator LED which is lighted when
power is applied. A "DMX VALID" LED indicator is
lighted when a DMX input signal is present.

supply which can provide 13 - 24 Volts AC or DC at
600 ma. The power supply provided with unit is
13VAC, 800 ma. The size of the power input

if the circuit board is damaged during a repair by other
than a Lightronics authorized agent.
