When emitting source came from set-top box (STB), DVD, video camera with remote function, remoter come with these equipments can be used directly on the receiver (TRV2400), while you don't have to operate the remote control of the AV equipments. Step one: Refer to connecting installation picture, connect transmitter (TXV2400), and confirm there are no barriers between transmitter's infrared window and infrared receiving window of program source. Step two: When enjoying programs from receiver (TRV2400), point remoter to remote receiving window of the receiver, then you can control AV equipments, which is easy and convenient for operation. Tips: Please pull 433 Mhz antenna of transmitter and receiver as straight as possible, and keep it far away from AV cables,to ensure no interference to signal transmission. In case of infrared remote malfunction, please check antenna's placement on condition that there is no placement problem with the transceiver. 1. Introduction 1.1 Function and Features GM2400 wireless A/V transceiver consists of Transmitter (TXV2400) and receiver (TRV2400). It adopts advanced 2.4GHz wireless transmission technology, with strong anti-interference and mobility. When used in conjunction with set-top box, DVD, VCD and etc, it can be installed easily, subject to no space limitation and without any use of wire connection. It can make audio and video transmitting easily available in every room at home, letting you enjoy HIFI audio and video freely at every corner at home. There are 4 channels, and the frequency scope ranges from 2.400GHz to 2.483GHz; In order to increase the flexibility and reliability, we prepare four selectable channels (2.414GHZ, 2.432GHz, 2.450GHz, 2.468GHz); 2.4 GHz wireless transmitter and receiver with 4 selectable channels (Tact Switch) Compatible with AV output equipments such as video recorder, video camera, digital camera and digital set-top box 433MHz infrared remote returning transmission, fully compatible with remote control of DVD/VCD/ digital et-top box Strong infrared emission, no need to install infrared emission extension cord Received image is clear and stable, with bright color, and stereo sound Support NTSC/PAL system video and stereophonic audio transmis- sion Complete hardware design, no need to install software, plug and play, easy and convenient TRV2400 Four transmission channels of 2.4GHz can be switched freely by pressing channel switch button. But only when the transceiver is in the same channel can video signals be transmitted normally. Panel indicator light for each channel selection mode goes as below: Please select Channel one or four, to avoid signal interference by wireless local area network (LAN),when there is LAN(802.11 or WiFi) in your family. 3.3 Channel Selection The first channel selection mode The third channel selection mode The second channel selection mode The fourth channel selection mode TXV2400 Tips: 1.2 Application A/V to A/V wireless transmission, can be used when many televi- sions share one DVD/VCD or one digital set-top box and etc. Video conference system in large conference room, and multimedia teaching in classroom. Connect to pick-up head for monitoring;can be used in security systems. Building and industry monitoring system, long-distance custody of children and patient .

WIRELESS A/V Transmitter&Receiver Operational Description GM2400 is wireless tranceiver for AV to AV transmitting. It consists of transmitter(TXV2400) and receiver(TRV2400). Main principle of GM2400 consists of two parts: The 1st part is AV transmitting:external AV1 & AV2 signal is transmitted by CD4053 which is controlled by single chip EM78P447 to 2.4G transmitting module. 2.4G receiving module will convert the received signal to AV signal for AV input equipments such as TV set and so on. The 2nd part is infrared remote feedback: remote control signal come from the user will be converted to digital signal by receiver TRV2400. Then the converted digital signal will be transmitted by ASK module of 433MHz after sampling coding of EM78P447. 433MHz receiving module of TXV2400 will demodulate the remote signal and then single chip EM78P447 will decode it. At last, the remote signal will be transmitted to infrared signal transmitting equipment.
