The Q-NEX NMP, functioning as a media processor for multimedia applications based on the TCP/IP protocol, serves as a central control box within an IoT ecosystem. It plays a pivotal role in establishing a smart campus system on the school’s existing network infrastructure. This system enables comprehensive control and management of multimedia classrooms, campus audio and video broadcasting, and live streaming, greatly assisting school IT administrators in executing a variety of operational tasks efficiently. Additionally, it operates as an integral component of the networked media system within a centralized network.

The Q-NEX NMP simplifies the daily IoT management of audio-visual equipment, streamlining the use of multimedia classrooms for educators. It offers a user-friendly interface through either a desktop Control Panel or a Touch Panel. Furthermore, each NMP seamlessly integrates with a wireless microphone system to enhance sound reinforcement capabilities, contributing to the overall efficiency of the AV control system.

Q-NEX Control Box (CBX), as the wireless control module of Q-NEX Networked Media Processor, easily builds a centralized control system for IoT devices over the campus.


There is no requirement. As long as the existing IFP/Projector/TV has an HDMI port, in addition to the HDMI port, and the display device supports RS232 or IR, the device can also be turned on and off through the network.

Please see the device connection diagram.

NMP mainly controls three types of devices:
1. Power control: such as turning on/off lights;
2. IR control: such as setting up the air conditioner;
3. RS232 control: display like IFP and projector.”

NMP firmware should not be upgraded unless necessary after leaving the factory.
If we need to debug the Q-NEX system, we will first consult our partners and agree on a convenient time to upgrade the equipment online. If necessary, we can also select only some devices or all devices to upgrade at the same time.
The smart panel firmware supports networked OTA upgrades.

NMP’s wireless microphone uses UHF pairing and transmission. The microphone receiver is built into the NMP. Each microphone has 24 channels that can be switched. Wireless microphones in adjacent classrooms will be set up with different channels; the pairing distance between the microphone and the NMP is within 0.5 meters, plus the barrier of the wall between classrooms. Basically, it is difficult to have cross-frequency phenomenon. In addition, even if teachers in nearby classrooms are linking at the same time, the receiver will give priority to the microphone in the local classroom with a stronger signal and a shorter linking distance.

As long as the student’s ID card is a card model that meets our requirements (m1-s50 card, frequency 13.56mhz), it can be used, that is, one card can be applied to multiple systems at the same time, both for the student attendance card system and Card system for our Q-NEX

NMP comes standard with one-to-two wireless microphones, which adopt UHF frequency binding and transmission. It is equipped with a lavalier microphone for teachers and a handheld microphone for students to answer questions. In addition, NMP can also support access to wired microphones, and we provide a mic in interface.

The power supply is a German standard WAGO port, with 1 in, 2 out, and one SPDT switch.
NOTE: The output power of the “Display” and “Screen” ports remains below 1200W.
The current carrying capacity of the “external” (SPDT) switch should not exceed 1200W.

Q-NEX’s broadcast complies with the definition of AV over IP.
What is AV over IP? AV over IP stands for “Audio and Video Technology Based on Internet Protocol”.
Essentially, it transmits digital audio and video data through networks such as LAN, WAN or the Internet. Q-NEX’s broadcast is to transmit audio and video content and live streaming media within the local area network through network connections. “

NMP broadcast belongs to multicast. Multicast refers to the simultaneous distribution of data to multiple points in communication.
multicast is group communication where data transmission is addressed to a group of destination computers simultaneously.

NMP control includes IR, RS232, and relay.
The external, display, screen, and lock ports on NMP use the relay part.
A relay is a switch that uses weak current to control strong current. The use of relays can reduce the risks when operating strong current. Other WAGO head interfaces use strong electricity.

NMP provides an IR interface. The standard configuration comes with an infrared transmitter cable. Connect one end of the cable to the NMP, and the other end of the transmitter is close to and pointed at the air conditioner. The principle is the same as the infrared remote control. For specific operations, please refer to the NMP installation video.
