2.  If you are using DMX control and this is the last fixture in the line, terminate the fixture with a 120 Ohm resistor. Please contact your ETC customer service representative to purchase ETC part number N4086. See Help from ETC Technical Services on page 2.

3. Connect the fixture to the power source.

DMX Dimming

When dimming via DMX, consider the following:

• When using DMX over Cat5, use Cat5e or better.
• Cable distance for full DMX daisy chain must not exceed 300 m (1000 ft).
• Up to 32 fixtures can be connected together into a daisy chain.
• The fixture cannot be controlled via Ethernet protocols and should not be directly connected to an Ethernet system.
• When DMX data is lost, the LED emitters turn off.
• The fixture uses a single DMX channel for intensity control.

DMX pinout

Line-dimming

When line-dimming the fixture, set the parameters as shown in the following tables to ensure that the dimmer is out of regulated mode.
(You may need to adjust dimmer settings for optimal fixture control).
In addition to the recommended settings in the following tables, you may need to increase the SCR Off Time from the default setting. Contact ETC for assistance in changing the SCR Off Time, or any other CEM classic, CEM+, or CEM3 settings. See Help from ETC Technical Services on page 2.
