Key Features:
- Distance Extension: Extends VGA video signal up to 60 meters (approximately 197 feet) over a single Cat5e or Cat6 Ethernet cable.
- Plug-and-Play: Generally, no software drivers are required for installation. You simply connect your VGA source to the transmitter, the display to the receiver, and link the two units with an Ethernet cable.
- Signal Transmission: Transmits the analog VGA video signal. Some models may also support audio transmission over the same cable (often with 3.5mm jacks).
- Passive or Active:
- Passive (No Power Required): Simpler models might be passive, meaning they draw power from the VGA signal itself, suitable for shorter distances (e.g., up to 30m or sometimes 60m at lower resolutions).
- Active (External Power Required): For longer distances and higher resolutions, the units often require external DC power adapters (typically 5V or 9V, included in the package). Active extenders usually provide better signal quality and stability.
- Compatibility:
- VGA Input/Output: Standard 15-pin HD-15 (D-Sub) female connectors for VGA.
- Network Cable: Compatible with standard Cat5e or Cat6 UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) network cables. Cat6 is generally recommended for optimal performance, especially at longer distances or higher resolutions, due to its better shielding and twist rate.
- Resolutions: Supports a range of VGA resolutions. For a 60-meter extender, common supported resolutions typically include:
- 1080p (1920×1080) / Full HD: Often supported at this distance, though performance can vary with cable quality.
- 1920×1200 (WUXGA): Some higher-end models might support this.
- 1600×1200 (UXGA)
- 1280×1024 (SXGA)
- 1024×768 (XGA)
- 800×600 (SVGA)
- 640×480 (VGA)
- Refresh Rate: Typically supports 60Hz, and sometimes higher (e.g., 75Hz, 85Hz) at lower resolutions.
- Adjustments (on active models):
- Gain Control: To adjust brightness and compensate for signal loss over long cables.
- Skew/Peak Adjustment: To compensate for color skewing (when colors arrive at different times due to varying signal speeds over the twisted pairs), which can cause blurry or ghosting images.
- Build: Often comes in a compact, lightweight design, sometimes with metal casing for durability and better heat dissipation.
Typical Components Included:
