INTRODUCTION
The ELE8088 HDMITM EXTENDER boosts your audio/video transmission distance up to 60m
(200ft) in HDTV 1080i format, 40m (130ft) in HDTV 1080p format, and 20m (65ft) in HDTV
1080p with 36 bit color depth. With two cost effective solid Cat-5/5e/6 UTP/STP cable, users can
readily extend HDTV sources from DVD players, Blu-ray Disc player, PS3, PC, and any other kinds
of sources compliant with TMDS to distant display monitors including HDMITM or DVI enabled TV
sets or LCD PC monitors. The ELE8088 also features with embedded IR input and output on both
transmitting and receiving units so users can control the source device or HDMITM display at romote
site via IR remote in di-directional IR pass-through.
The ELE8088 includes two units: transmitting unit and receiving unit. The transmitting unit sends
the HDMITM or DVI signals received from the source device and receives IR signals from the
receiving unit or sends the received IR signal from the transmitting unit via two low cost Cat-
5/5e/6 cables. The receiving unit is responsible for equalizing the audio/video data received from
the transmitting unit and sends the IR signals received from the IR receiving to the transmitting
unit or receives IR signals from the transmitting unit . The transmission distance between the
audio/video source and the display can be up to 60m (200ft) at HD resolution (720p/1080i), or
40m (130ft) at Full HD resolution (1080p). With 8-level digital signal equalization control on the
receiving unit, users can adjust the signal level equalization scale to the received audio/video
signals, and therefore optimize the transmission distance between source and display.

keystone jack along the transmission path will kill the transmission performance
signicantly!

1. Connect a HDMITM or DVI source (e.g., a Blu-ray Disc player) to the transmitting unit.
2. Connect a HDMITM or DVI display (e.g., a HDTV) to the receiving unit.
3. Connect two solid Cat-5/5e/6 UTP/STP cable between the transmitting and receiving
units.
4. Make sure these two solid Cat-5/5e/6 UTP/STP cable are tightly connected and not
loose.
5. If you want to control the source devices at display side, plug in the IR blaster to the
transmitting unit and the IR receiver to the receiving unit. If you want to control the
display at source side, plug in the IR receiver to the transmitting unit and the IR blaster
to the receiving unit.
6. Plug in the 5V DC power supply unit to the latch-locking power jack on either the
transmitting unit or the receiving unit.
7. If you see ickering or blinking image on the display, adjust the rotary control switch
to improve the cable skew. 0 stands for the strongest HDMITM signal level for longest
possible transmission length while 7 stands for the weakest HDMITM signal level for short
transmission length. Try adjusting the signal level from 7 to 0 to nd the optimal setting
for the HDMITM over CAT5 transmission.

1. When adjusting the signal level on the receiving unit, please dial the rotary control
switch from 7 to 0 and stop turning the rotary switch whenever the audio/video is
playing normally. Inappropriate signal level setting may cause overpowering issue that
would shorten the product life signicantly!
2. Wrongly insert IR blaster and IR receiver to wrong 3.5mm infrared sockets may result in
the failure of the IR extenders. Please check carefully before plugging in the IR extender
to the respective IR sockets.
3. If the DVI or HDMITM device requires the EDID information, please use EDID Reader/
Writer to retrieve and provide DVI or HDMITM display EDID information.
4. All HDMITM over CAT5 transmission distances are measured using Belden 1583A CAT5e
125MHz UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
5. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type
of HDMITM sources, and the type of HDMITM display. The testing result shows solid UTP
cables (usually in the form of 300m [1,000ft] bulk cables) can transmit a lot longer
signals than stranded UTP cables (usually in the form of fixed length patch cords).
Shielded STP cables are better suited than unshielded UTP cables. A solid UTP Cat-
5e cable shows longer transmission range than stranded STP Cat-6 cable. For long
extension applications, solid UTP/STP cables are the only viable choice.
6. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better
performance.
7. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6
cable, one can use shielded STP cables to improve EMI problems, which is worsen in
long transmission.
8. Because the quality of the CAT5/6 cables has the major effect on how long the
transmission limit can achieve and how good is the received picture quality, the
actual transmission range is subject to one's choice of Cat-5/5e/6 cables. For desired
resolutions greater than 1080i or 1280x1024, a Cat-6 cable is recommended.
9. If your HDMITM display has multiple HDMITM inputs, it is found that the rst HDMITM input
[HDMITM input #1] generally can produce better transmission performance among all
HDMITM inputs.
