  • Sends PC or HD video and bi-directional RS-232 over single Catx
  • Wide bandwidth to transmit WUXGA signals (1920x1200 / 60hz) or HD Analog Component (1080p)
  • Compensation for UTP cable to 500 ft
  • No power supply required at local sender - when powered from VESA compliant VGA Source
  • DDC compliant EDID emulation on the Sender
  • Supports all baud rates to 115 Kbps
The Model UV232B Kit is used to send high resolution video and full-duplex RS-232 over a single twisted-pair cable to a remote location up to 500 feet away.

The input video can be from a RGBHV (PC video to WUXGA) or YPbPr (HD analog component to 1080p).

DDC compliant EDID emulation assures proper PC boot-up with video output.

The Bi-directional RS-232 can be used to control LCD’s or Projectors that have RS-232 control, or connect to a compatible touch-screen LCD.

Applications include kiosk solutions, conference halls, digital signage, interactive operator systems, factory or laboratory data acquisition and control, and more.

When the Sender is powered from a VESA compliant VGA source (+5v on Pin 9) a power supply (included) is only required at the Receiver.
If the source is not VESA compliant in that regard, or if the video is YPbPr (using a 3 RCA to HD15 input cable), then a power supply (included) is needed at both Sender and Receiver.

The kit includes a local unit (Sender) that includes a VGA & serial cables, plus a remote unit (Receiver) with two power supplies.

It is recommended that for best image quality low-skew UTP cables be utilized (such as Hall Research’s Zero-Skew cables), otherwise at long distances (>200ft) and high-resolutions, RGB skew may be present and a separate skew corrector would be necessary (HRT Model SKU-RGB).
