Control Input/Output Connections
All DE90-3000 Series retrot control systems come with a variety of control
input and output (I/O) capabilities. All I/O connections are terminated on the
Backplane.
Breakaway type connectors are supplied for all I/O connections.
• Use wire size #28 to #12 AWG. Strip insulation length to 0.3" (7.5mm).
• Torque terminations to 3.6 IN-LBS (0.4 NM).
NOTE: For connection use copper wire only, rated for 167°F (75°C) minimum.
Dual DMX Input and Thru
• DMX A terminates to J1 and J2 connectors.
• DMX B terminates to J3 and J4 connectors.
• Complies with USITT DMX512-A (ANSI E1.11 - 2008), standard protocol
for digital data control.
• Recommended cable is Belden 9829, 9842, Cat 5 or equivalent
(low-capacitance, twisted pair).
• Wiring must follow a daisy-chain topology.
• Maximum of 32 receiving dev-ices on a single DMX line.
• Maximum cable length is 1,500 feet (455 meters).
• For more information, Google DMX, or visit:
http://old.usitt.org/DMX512FAQ.aspx
NOTE: Ensure only the last (end-of-line) DMX receiving device is terminated!
+12VDC Power Supply Output
• A regulated +12VDC power supply is available for powering
external devices.
• Terminate on +12V and COMMON of T6 connector.
• External devices should not exceed the maximum combined
current draw of 200 mA.
0-10VDC Analog Inputs or Load Shed Contact Inputs
• Four (4) analog inputs terminate on J6 connector.
• Inputs can be congured for normal or load shed mode of operation.
• Inputs can be patched to any combination of dimmer output circuits.
• Programmed in the “ANA MODE” and “ANA PTCH” menus.
