General Specification
DCE is a DVI, surround digital audio and analog audio extension system over CAT5 cable
for long distance up to 165ft.
Its compact & durable design and low power consumption makes it an ideal solution for
connection for high definition video and audio signal of digital displays such as LCD/Plasma
monitor and Projector.
DCE’s unique circuitry design for the best quality of HDTV and low-power consumption
design eliminates the need of two CAT5 connection between transmitter and receiver.
Purelink’s new DCE only requires one CAT5 connection. This CAT5 connection enables to
minimize electrical noise and EMI free that is ideal for long distance extension of high
definition DVI signal with embedded audio.
DCE’s intuitive LCD panel on both transmitter and receiver show the status of the video and
audio signals including the current signal image format and audio format. With this
information DCE provide, any user can easily view helpful diagnostic information.

Main Features
1. Zero loss & Zero noise delivery of digital high definition video and audio signal using
UTP connection, DCE delivers HD signals over CAT-5 cable without loss or digital
interference maintaining the clarity and colors. Noise cancellation and error correction
logic enhances video and audio signals over long distance.
2. Built-in signal repeater to support longer distance between the source and the DCE
transmitter & DCE receiver and the display. This Signal Repeater logic supports up to
50ft copper based DVI cables.
3. Compact and Robust Module Design
4. Long distance (Up to 165ft at 1080p or lower signal) over cost effective single CAT-5
cable
5. DVI video signal and Digital or Analog Audio can also be transmitted via CAT5 cables.
6. Full EDID Management
Saving/Emulating display’s EDID in the transmitter module enhances reliability and
compatibility with various displays.
7. HDCP (High-bandwidth Digital Content Protection) Compliant.
8. DDWG DVI ver.1.0 Standard.
9. Signal Status LCD panel on both transmitter and receiver modules video and audio
signal information is displayed on the LCD panels to help understand the signal even
before the display is connected. Display Resolution, refresh rates and audio signal
status are intuitively displayed on the modules.

Installation and Connection Instructions
1. Turn off both the video source and the display before connecting any cables.
2. Connect CAT5 cable between the DCE transmitter and the DCE receiver.
3. Connect DVI cable between the source and the DCE transmitter AND the DCE receiver
and the display.
4. Connect the power supply unit to both DCE transmitter and receiver module.
5. Turn on Display.
6. Turn on Video Source.
EDID Management
For reliability and correct signal transmission of the video source, EDID emulation is
recommended. Please follow the steps below;
1. Connect the DCE transmitter’s DVI input port to the display’s DVI input port.
2. Press and hold EDID button for about 2 seconds until the display’s EDID is successfully
saved on to the transmitter. “EDID PASS”message on the LCD panel indicates
successful EDID save. “EDID ERROR”message indicates failed EDID save.
<Please refer to the drawing below for more information>
3. If you like to read/save other display’s EDID, then repeat the step #1~ #2.
** Please note factory default EDID is based on 1080p. **
<EDID Save Successful> < EDID Save Failed>

Signal Status LCD Display
The LCD panel on DCE transmitter and receiver shows the current signal status.
