VGA video extender and stereo analog audio through Cat.5 UTP cable. System of components of the prestigious manufacturer Rextron that integrates transmitters (models # LP4x), repeaters and receivers (models # LP5x). The system consists of at least one transmitter and one receiver, although a maximum of 2 chained repeaters can also be added between transmitter and receiver, to achieve a maximum of 900m distance (3 300m sections).
Specifications
- 1 audio and video input: 1 x VGA (HD15 male) and 1 x stereo audio (3.5 mm female minijack).
- 1 local audio and video output: 1 x VGA (HD15 female) and 1 x stereo audio (minijack 3.5mm female).
- 4 UTP outputs: Four female RJ45 ports for connection to remote repeaters of the same range (model # LP51) or to receivers (models # LP52 or # LP53).
- Status indicator LEDs.
- EDID function that allows to obtain the best output resolution.
- Module that replicates audio and video input in a local audio and video output, in addition to having 4 RJ45 outputs for interconnection with other repeater or receiver modules.
General characteristics of the system
- System of transmitters, repeaters and receivers that allows the transmission of stereo audio and VGA video at a maximum distance of 900m.
- Video transmission at Full HD resolution 1080p (1920 x 1080), WUXGA (1290 x 1200) and UXGA (1600 x 1200).
- Stereo analog audio transmission.
- Automatic detection of the type of video source.
- Supports over-power, ESD and EFT protection.
- Innovative control system through multi-function potentiometer. It allows volume adjustment, video gain, video equalization and RGB skew.
- The multi-function wheel also allows the function of switching off and on of the local ports and independently for each port.
- Size of the modules: 139 x 99 x 22 mm.
- It works with 12 VDC power supply. Includes 12 VDC to 1.5 A source
Examples of use
- Transmission from 1 port to 300m: Use 1 # LP41 and 1 # LP53. 2 VGA with audio can be connected to the transmitter module. 2 VGA with audio can be connected to the receiver module.
- Transmission from 1 port to 200m: Use 1 # LP41 and 1 # LP52. 2 VGA with audio can be connected to the transmitter module. 2 VGA with audio can be connected to the receiver module.
- Transmission of 4 ports at 300m: Use 1 # LP42 and 4 # LP53. 2 VGA with audio can be connected to the transmitter module. In each of the 4 receiver modules can connect 2 VGA with audio, ie up to a total of 8 VGA with remote audio.
- Transmission from 1 port to 900m: Use 1 # LP41, 2 # LP51 and 1 # LP53. 2 VGA with audio can be connected to the transmitter module. 2 VGA with audio can be connected to each of the 2 repeater modules. 2 VGA with audio can be connected to the receiver module. In total 6 VGA can be connected with remote audio.

HD (High Definition) is the technical standard designed to surpass the resolution limitations of standard definition (SD) systems, offering higher pixel density.
The architecture of High Definition is based on a significant increase in spatial resolution, typically using a 16:9 aspect ratio. At the hardware level, HD requires an image processor capable of managing dense data streams and high-speed communication buses to minimize latency in digital signal transmission.
| Specification | Standard Value |
|---|---|
| Minimum Resolution | 1280 x 720 pixels |
| Aspect Ratio | 16:9 |
The deployment of the HD standard has reconfigured data storage and transmission paradigms in modern networks, serving as the minimum baseline for professional video.
Progressive and Interlaced Scanning
HD systems operate using progressive or interlaced modes to optimize bandwidth usage.
Key Advantages
- Superior clarity and texture detail.
- Native widescreen format.
- Integrated digital multichannel audio.
Reference standard for the modern audiovisual industry.
