Hohida Science and Technology Video Transmit Module Overview

1-way HDMI HD or AV Scriptures Video H264 encoded OFDM wireless transmission 1-way two-way wireless transmission Ethernet port, 2-way two-way wireless transmission RS232 serial port, 1 channel single wireless transparent TTL serial port 1 TTL 1 channel audio output, directly pick 1W speaker Maximum support 1080p @ 60fps H.264 encoding, compatible with other various resolution, frame rate coding; MINI HDMI input: 1080 60p, 1080 50p, 1080 30, 1080 50i, 1080 30i, 720 60p, 720 50p, 720 30p, ..., various modes adaptive; AV input: 720x480 60i (NTSC), 720x576 50i (PAL), mode adaptive At the same time, it supports the 1-way Ethernet and 2 RS232 serial port wireless two-way transparency, and the 1-way TTL serial port is one-way wireless transmission; Support audio input and output to implement two-way audio wireless transmission function; Double antenna emission and reception, MIMO work mode; Support wireless band: 2304 ~ 2390MHz, center operating frequency point can be configured; Radio bandwidth: 4MHz or 8MHz, the vacation rate is up to 25Mbps; Maximum transmit power: 1W; Receive sensitivity: -102dBm (4MHz bandwidth); Wireless link encryption and decryption: 128 bit AES; Video_tx_led: Flash when the video is transmitted; LINK_LED: Displays the wireless signal strength at the time of wireless transmission, a total of 3 lights. The stronger the signal, the more the light is on; Support wide voltage input: 7 ~ 24V; Module Size: 70 * 45 * 13.5mm, does not include the size and heat dissipation device of the interface edge of the interface device. Weight 34 g (no heat sink). Silica two-way wireless transmission link HD map transmission module implementation function: 1) Multiple receiving modules can interface with a transmit module for bidirectional wireless transmission; 2) Ethernet port corresponding to the transmitting module to achieve a two-way OFDM wireless transmission; 3) RS232_A of the transmitting module to achieve a two-way OFDM wireless transmission of the RS232_A serial port of the receiving module; 4) The RS232_b of the transmitting module corresponds to the RS232_B serial port of the receiving module to achieve two-way OFDM wireless transmission; 5) The TTL data serial port corresponding to the receiving module implements the TTL data serial port of the receiving module to achieve one-way OFDM wireless transmission; 6) The MIC audio input of the receiving end corresponds to the speaker output of the transmitter; 7) The transmitted HDMI or AV audio is output to the HDMI and AV interface to the receiving end together; 8) Connect the transmitting end and the received parameter serial port with the receiving end via the Hyroda Passage Module (see the Jarda Command], such as setting the encoded rate of the transmitting end, the time of the receiving end, and the like; 9) The wireless transmission and receiving parameters of the transmit terminal and the receiving end can be set by the network connection. 10) Measured data: The air-to-ground wireless transmission distance exceeds 10 kilometers, and the wireless transmission distance is more than 2 kilometers.
