The American Lighting REC-DMX-RJ45A-5CH is a 5-channel DMX decoder designed for controlling LED fixtures. It requires a 12-24V DC power supply and a DMX master controller (both sold separately). The device supports various fixture types, including single color, Tunable CCT, RGB, RGBW, and RGB+Tunable CCT. Always ensure power is disconnected at the source before installation.
Installation
Wiring the Receiver:
- Determine the mounting location and secure the receiver using the mounting tabs.
- Connect the fixture to the output terminals (CH1-CH5) following the fixture's specific wiring diagram and ensuring correct polarity.
- Connect the 12-24V DC power supply to the power input, ensuring correct polarity.
- Do not connect cables while the power is on.
Interconnecting Receivers:
- To daisy-chain multiple receivers, connect the D- and D+ terminals from the first controller to the D- and D+ terminals on the second controller, matching polarity.
- Connect ground to ground on each unit.
- Alternatively, use XLR3 or RJ45 ports to interconnect units using appropriate cables.
Operation
The receiver features a digital display and four buttons: Back, Enter, Up, and Down.
- Mode Selection: Before configuring, choose the operating mode: run1 for DMX Decoder Mode or run2 for Standalone Mode.
- Navigation: Use the Up and Down buttons to toggle through menu selections. Use Enter to select and Back to return to the main menu.
- Factory Reset: Press and hold both the Back and Enter buttons until the digital display turns off, then release. The system will reset to default settings.
