Chapter 2: Overview
2. Overview
2.1 Introduction
The VSPX-HDMI1X4-TX transmitter works with the VSPX-HDMI-RX or VSPX-
HDMI-CSRX receiver to extend high-definition video and high-quality audio to
different locations over a long distance. The transmitters are cascadable,
enabling you to increase the number of total displays. The input HDMI source
can be duplicated and distributed to up to four HDMI enabled displays linked by
CAT5/5e/6 cables with HDMI over CAT5 receivers (VSPX-HDMI). If you only
need a single port transmitter, buy the compatible 3D HDMI extender kit
(VX-HDMI-TP-3D40M).
The VSPX-HDMI1X4-TX also has a local HDMI output for monitoring. With
built-in equalization, the input HDMI cable can be extended up to 66 feet
(20 meters) using Full HD, making the overall transmission distance better when
compared to generic HDMI splitters.
The VSPX-HDMI-CSRX receiver works with the VSPX-HDMI1X4 transmitter,
VSPX-HDMI-RX receiver, or VX-HDMI-TP-3D40M extender kit to distribute
HDMI/DVI video sources to up to ten displays in a daisychained connection via
CAT5/5e. By using the VSPX-HDMI1X4-TX transmitter and making four separate
chains, the number of displays can be increased to a total of 40. The cascade
ability allows pure digital video and audio broadcast station by station and
extends HDMI compliant video and audio anywhere.
The VSPX-HDMI-RX receiver works with the transmitter or VSPX-HDMI-CSRX
cascadable receiver to extend high-definition video and high-quality audio over
a distance via CAT5/5e/6 cable. The receiver works with an HDMI transmitter or
splitter over single CAT5 and enables you to extend HDMI compliant displays
almost anywhere.
2.2 Features

2.2.3 Additional Features for VSPX-HDMI-RX
• Extends up to 200 feet (60 m) over CATx cable using HD (720p/1080i).
• Extends up to 130 feet (40 m) over CATx cable using Full HD (1080p).
• Wallmountable.
NOTE: The cable length depends on the characteristics and quality of the cables.
Higher resolutions and longer transmission distances require low-skew
cables (<25 ns/100 m) for best performance. We recommend using solid
core CAT6 cable.
2.2.4 Additional Features for VSPX-HDMI-CSRX
• Regenerates and outputs the HDMI signal.
• Support for stereo audio analog or 7.1ch audio via HDMI interface.
• Extends up to 200 feet (60 m) (720p/1080i) over CATx cable.
• Extends up to 130 feet (40 m) (1080p) over CATx cable.
• Up to three layers of cascaded units can be used to reach a total distance of
up to 393 feet (120 m).
• Wallmountable.
NOTE: The cable length depends on the characteristics and quality of the cables.
Higher resolutions and longer transmission distances require low-skew
cables (<25 ns/100 m) for best performance. We recommend using solid
core CAT6 cable.
