Product Introduction

The Q-NEX Networked Media Processor integrates Ethernet connectivity into the device control system, enabling users to remotely control the device. It is primarily designed to assist school IT administrators in effectively managing various electronic facilities within a school, thereby freeing teachers from the complexities of operating a multimedia classroom.

1.1 Network Environment Requirement
To ensure optimal integration, school network needs to meet specific requirements tailored for the NMP.

1. The school should allow NMP to access the Internet.

2. Whitelist Network Control Requirements:
   If the school employs whitelist network control, the following domains should be added to the whitelist:
   – “https://qnextech.com/” (Primary Domain)
   – “https://mg.qnextech.com/” (Secondary Domain).

3. IP Address and Port Requirements:
   The school network should allow access to the following addresses:
   – 110.90.11.185:80 (HTTP)
   – 110.90.11.185:443 (HTTPS)
   – 110.90.11.185:12573 (NMP Communication Service)
   – 27.151.13.85:12583 (NMP Upgrade Service).

4. MAC Address Control Requirements:
   If the school implements MAC address control, the MAC addresses of the following devices should be added to the allowed access list:
   – NMP
   – Touch Panel

5. NMP Network Configuration:
   – NMP must be connected to the router via a wired connection; NMP does not support wireless network connection.
   – NMP and Touch Panel should be on the same LAN.
   – If there is a Media Server (broadcast and live streaming), ensure that the Media Server, NMP, and Touch Panel are on the same LAN.
   – The firewall should open the following ports for the Media Server:
   • 12570 (Broadcast Port)
   • 1935 (Streaming Port)
   • 80
   • 443

6. NMP IP Address Setting:
   – To prevent issues caused by NMP IP changes, it is recommended to set the NMP IP address as static.
   – Ensure that before the initial use of NMP, the Touch Panel successfully connects to NMP using this IP.

7.  VLAN:
   NMP does not support VLAN. NMP, Touch Panel, and Media Server should be connected to the campus network as described above but should not be on VLAN.

3.3 Device Control
3.3.1 Power Control

This section governs the power management and operational control of connected devices through interfaces like Display, Up-Down, and External Wago connectors. Users can regulate power distribution and device states by NMP.
Power Specifications ：

1. NMP device maximum power: 2000W.
2.  Display port maximum power: 1200W.
3.  External port maximum power: 1200W. (This power does not count towards NMP’s total power consumption)

3.3.1.1 Display
The Display Wago interface serves to provide power to display devices such as IFPs and projectors.
Additionally, it facilitates controlled shutdown procedures (with RS232 port) for these devices to mitigate the risk of damage caused by sudden power loss.

Connection Steps:

1. Replace the device plug with the WAGO connector. Refer to 3.1.1 WAGO Connector Installation Guide for Wago connector installation instructions.
2.  Connect the WAGO connector to the DISPLAY port of the NMP.
3. Devices can still be powered on or off by solely connecting to the DISPLAY port.
   Note:
   For devices requiring controlled shutdown and delayed power-off settings (For example: IFP, projector), connect them to the NMP’s RS232 port. This ensures that devices receive proper shutdown instructions before power is cut off, and allows for adequate cooling before shutting down completely.

3.3.1.2 Up-Down
The Up-Down Wago interface is specifically designed for controlling projection screens. Users can remotely raise or lower the projection screen via the NMP’s control options, including the Q-NEX Console, mobile app, or Touch Panel.

Connection Steps:

1. Replace the plug of projection screen with WAGO connector. Refer to 3.1.1 WAGO Connector
   Installation Guide for Wago connector installation instructions.

2. Wire Configuration
   – Connect the “Up” wire to the “L” port of the Wago connector.
   – Connect the “Down” wire to the “N” port of the Wago connector.
   – Connect the “N” wire to the “G” port of the Wago connector.

3.  connect to Up-Down port.

: This wiring configuration is exclusively for use with projection screen curtains.
3.3.1.3 EXTERNAL
The External interface on the NMP enables flexible lighting control. Users can directly manage lighting or integrate it with an SPDT switch for customized automation and centralized control. Control settings can be adjusted via the Touch Panel and Web-Console.

There are two methods to achieve lighting control with NMP: direct connection and integration with an SPDT switch.

1. Direct Connection to NMP:
   In this mode, user gains the ability to manage the lighting control by NMP.

：The current-carrying capacity of the“External” should not exceed 1200W

2. Integration with SPDT Switch:
   By replacing the existing switch panel with a Single Pole Double Throw (SPDT) switch and connecting it to NMP, both NMP and the switch panel gain control over the light.

：The current-carrying capacity of the“External” should not exceed 1200W
After completing the wiring for the external port, you can control it on the Touch Panel and Web-Console.
3.3.2 IR Control
The NMP is equipped with both an IR IN and an IR OUT interface, allowing users to manage IR devices efficiently.

To control IR-enabled devices (e.g., air conditioner, TV, projector), NMP supports batch application of infrared control codes, enabling efficient control without repetitive learning.
Here’s a simplified guide for using IR functionality with an air conditioning unit:

1. Check if your air conditioner brand is in the Q-NEX database. If your air conditioner is recognized in the Q-NEX database, identify the control codes to manage and control it through the Touch Panel or Webconsole。
2. If not in the database, use IR Learning on the Touch Panel or Web-console for control.

3.3.2.1 Air Conditioner-Identified in the code database
Follow these steps:

1. Connect the infrared emitter to the ‘IR’ port on NMP, aim it at the air conditioner, ensuring no obstacles between the emitter and the air conditioner:
   

2. Log in to Q-NEX Console -> Dashboard -> Devices -> Processor Manager. Choose your NMP device, inthe ‘IR Control’ module, click on the ‘Edit’ button:
