1. Product Overview

AOSHOWAS-832M is a professional Art-Net network LED pixel sub-controller, which supports SPI and DMX512 digital pixel lamps. It has 8 independent outputs, Art-Net real-time control, offline playback of master SD card, multi-level gray scale control, software Gamma correction and other functions.

The device supports 32~65536 gray scale control mode, which can optimize the light brightness change and color gradient effect according to the actual ability of LED driver chip and control system.

The AS-832M adopts a system architecture that combines master control and branch control. When running offline, the lighting effect is uniformly stored in SD cards compatible with the main controller such as AS-SDMX. For the same project, only SD cards need to be configured at the main controller. Each AS-832M sub-controller does not need to insert cards separately, which is convenient for later program update, equipment maintenance and unified management.

Each AS-832M is equipped with 8 independent output ports as standard. In Art-Net mode, 6 Universe are allocated per port by default, and the theoretical capacity of RGB continuous channel mapping is 1024 pixels. In the working mode with 170 full RGB pixels per Universe, each port is 1020 pixels. Under the specified drive IC and offline working mode, the nominal maximum load of the whole machine is 6144 pixels.

Please note that 1,024 pixels per port is the theoretical value for a continuous mapping of 6 × 512 channels, while 1,020 pixels per port is the calculated value for each Universe to independently accommodate 170 RGB pixels. These two options do not mean that all firmware supports the corresponding mapping method; the actual behavior depends on the controller firmware, port configuration, and driver mode.

The product is compatible with MADRIX, TouchDesigner, MadMapper, Resolute Arena, MA Lighting, and other professional lighting control systems that can output Art Net compatible data.

It supports the management of controller ID, driver IC, port parameters and offline configuration through supporting software such as LEDShow and VideoLEDShow. It is suitable for stage art, bar nightclub, KTV, night tour of cultural tourism, architectural lighting, LED point light source, 3D matrix lamp and immersive digital art installation.

2. product technical specifications

1. Basic Technical Parameters

2. Art-Net output capacity parameters

The aforementioned Universe capacity represents the channel calculation result and does not indicate that the controller can achieve the corresponding total number of pixels under all protocols, driver ICs, and refresh rates.

It is particularly important to distinguish: the theoretical allocation for 8 ports × 1020 RGB pixels results in 8,160 pixels, yet the device specifications also state that the maximum pixel count for the entire system in the specified mode is 6,144. Therefore, the 8,160 pixels cannot be directly advertised as the AS-832M’s actual full-machine guaranteed load capacity.

RGB occupies 3 logical control channels per pixel.

RGBW requires 4 logical control channels per pixel.

Universe and the number of pixels should be configured according to the actual color mode.

3. Select based on the control mode.

When real-time visual effects, music interaction, and software animation are required, Art-Net can be used for online control.

When independent playback of preset programs is required, an offline control solution compatible with AS-SDMX master control can be adopted.

4. Plan the network based on the number of controllers.

Large-scale projects should centrally plan controller IDs, IP addresses, universes, ports, and luminaire zones.

The total number of controllers, network bandwidth, and system refresh rate shall be verified based on the specific project requirements.

5. Allocate pixels based on the overall load-bearing capacity of the system.

For the specified driving mode with a nominal 6,144 pixels, engineering design shall be based on the system-level constraints of that mode, rather than simply summing the theoretical capacity of the eight output channels.

For other modes such as UCS512 RGB, RGBW, and DMX512, calculations should be performed separately based on their respective rated load capacities.
