FRONT PANEL LED INDICATORSDATA – DMX input signal LED indicators are located on left side of the front panel and indicate whether
the DMX signal is received at the input. DMX input signal LED indicators have two modes:• Off: DMX signal is not present• Blinking: DMX signal is present.
RDM – RDM signal processing mode LED indicator has two modes:• Off : RDM mode is turned off and splitter works in DMX-only mode
• On: RDM mode is activated (Opto-Splitter passes RDM signal). Note: Opto-Splitter Mini RDM has
RDM always enabled.
Note: Ensure all devices support RDM. Some DMX receiving chips are not able to process an RDM signal,
casuing the device to behave erratically. If a problem occurs contact your device manufacturer.

OPTO-SPLITTER 2X8, 2X8 RDM, AND 2X10 RDM UNIVERSE INDICATORSA Universe – LED indicators are located at each of the DMX splitter outputs, indicating whether theoutput is connected to the DMX input A. The LED indicators have two states:• Off: The DMX signal output is not connected to input A• Blinking: The DMX signal output is connected to input A
B Universe – LED indicators are located at each of the DMX Splitter outputs, indicating whether theoutput is connected to the DMX input B. The LED indicators have two states:• Off : The DMX signal output is not connected to input B• Blinking: The DMX signal output is connected to input B
