Typical Control Link Wiring Diagram

Wiring Notes:

1.

  Connection of the control to the Control Link should be made inside the ODMX-512 or in a junction box (provided by 

others) located no more than 8 ft (2.5 m) from control.

2. 

Control link wiring must not be run in the same raceway as line voltage power.

3.

 Total Control Link length is not to exceed 2000 ft (600 m) unless signal is boosted by a link booster (MX-RPTR).

4

. Data cable shield must be maintained throughout the Control Link. 

DO NOT

 connect the shield to earth/ground. 

5.

  Refer to your lighting control system Installation Guide and Lutron job drawings for power cable and data cable (Control 

Link) wiring restrictions and limitations.

6.

  Control Link requires a LT-1 (Link Termination Assembly) at each end of the Control Link. Refer to LT-1 instruction sheet for 

location and installation information.

•  

ODMX-512 is one unit load on the DMX512 link as per the 
DMX512/1990 and EIA-485 standards.

•  

Proper DMX512 link wiring practices are required.

•  

Proper external DMX512 link termination 
resistor is needed if the ODMX-512 is at the 
end of the DMX512 link.

•  

Maintained switch closure must be dry or wet 
contact closures with:

 

-On state saturation voltage less than 1.0 V

-

 

 - 

Off state leakage current less than 10 µA
