Ascentic LM8 Series 12V and 24V LED Controllers User Manual

User ManualLM8 Series12V and 24V LED Controllers

Introduction

The Ascetic LM8 LED controllers are available in 24V or 12V versions. Up to eight LEDs or arrays can be controlled via serial commands. There are two LED connection options for the LM8 series: one with removable screw terminal blocks (shown here) and one with barrel ports.

Package Contents

Before installing this product, please check the packaging and make certain the following items are contained in the shipping carton:

• LM8 light bar control module
• Power supply: 12V or 24V DC, 1.5 Amps
• 8x Terminal blocks (screw terminal modules only)

Features

• Turn on one or more outputs.
• Control brightness on each output (PWM).
• Expand the system by linking multiple units via RS-485.
• Receives human-readable serial commands via RS-232.
• Share power between multiple devices using the 12V power bus.

RS-232 CommandsSerial command examples are shown in the table below. Baud rate: 115200. Adjust Straight / Null switch as needed.Standard RJ-45 cable, or RJ-45 to 3.5mm adapter, PN: 801-373.

• The brightness range (PWM) is 0-255
• Multiple units or outputs must be separated by commas
• The device address is set by the ID switch (base address of 24 + binary) e.g. ID 30 = turn on DIPs 2 and 3

RS-485 Communication BusThe RS-485 communication bus is for expansion or use with custom applications. Standard commands include LED_OFF, LED_ON, LED_PWM, and LIGHTS_OFF. Baud rate: 57600. When linking multiple LM8 modules, use the ID switches as shown above to designate a different address for each one.Power Caution: LED voltage must match power supply voltage (12 or 24 volts). Connect the 12V or 24V power adapter to the port marked Power Input. Multiple LM-8s can run off of a single power supply (depending on peak system demands). Contact your Audio Authority account manager for more details.LEDsConnect LED arrays to the output ports on the Model LM8. Observe correct polarity (center positive or left positive) when connecting to LED strips or bars.

LED Specifications

• Max current output per position is 5A @ 12V (60W)
• Max current rating for the unit is 12A @ 12V (144W)*Variance depends on wavelength and intensity of LED strip.

Multi-Color LED Arrays

The LM8 works with the common anode, analog multi-color strips but not digital LED strips. Connect a common positive contact on terminal 1 and the three colors to the negative terminals of 1, 2, and 3. With the wiring shown, use the commands below for LED color mixing. For more detailed mixing, use PWM commands.

Installation

• Attach the LM8 to a flat surface with the screws provided.
• Connect LED terminals securely, observing correct voltage and polarity.
• Connect RS-485 cable from the LM8 to the serial host.
• Connect the power adapter to AC power, then to the power port.
• Call Audio Authority with questions that are not addressed in this manual.

EXAMPLE: As push-buttons select product positions, the MediaHub plays the video track and turns on the LED simultaneously.
