The HDMI-SPL-2108C 2x8 HDMI 1.3 over Single CAT5 Distribution Amplifier provides the most flexible
solution by which the high definition video and high quality audio can be transmitted to different locations
over a long distance. The devices are cascadable, allowing you to extend HDMI compliant displays almost
anywhere. Installed with a 2x1 HDMI 1.3 compliant switch, one of the input HDMI sources can be duplicated
and distributed to up to 8 HDMI enable displays through cost effective Cat-5/5e cables and RJ-45 to HDMI
mini-extenders (HDMI-EXT-1111C-RX). With the built in equalization, the input HDMI cable can be extended
up to 20 meters long under Full HD, and make the overall transmission distance superior than regular HDMI
splitters or matrix switches in the market.
Features
z State-of-the-art Silicon Image (founder of HDMI) chipset embedded for upmost compatibility and
reliability
z HDMI 1.3c compliant
z HDCP compliant
z Regenerates the HDMI signal
z Acts as a 2x1 HDMI switch plus a 1x8 HDMI over CAT5 splitter
z Supports default HDMI EDID and has the ability to learn the EDID of displays
z Extends up to 20m of input HDMI cable
z Extends up to 60m of output CAT-5/5e/6 UTP cable under HD (720p / 1080i)
z Extends up to 40m of output CAT-5/5e/6 UTP cable under Full HD (1080p)
z Pure unaltered uncompressed 7.1ch digital HDMI over UTP cable transmission
z Allows cascading

The length depends on the characteristics and quality of the cables. Higher resolutions and longer
transmission distances require low skew cables (<25ns/100m) for best performance. Unshielded CAT6
with metal RJ-45 connectors is recommended.

Pin-1 and pin-2 are for HDMI INPUT 1; while pin-3 and pin-4 are for HDMI INPUT 2
2
If the HDTV shows video but without audio, please set audio mode to stereo.
3
Factory default setting is pin-1 at OFF[©], pin-2 at OFF[©], pin-3 at OFF[©] & pin-4 at
OFF[©] for 1080p with stereo.
4
If you encounter any unsolved audio/video output problem during system installation,
please dial the DIP switch to pin-1 at OFF[©], pin-2 at ON[ª], pin-3 at OFF[©], & pin-4 at
ON[ª] for safe mode to enforce the most compatible 720p stereo output for system check.
However, the safe mode cannot be initiated if your HDMI sources are set to enforce 1080p
output. In this case, please reconfigure your HDMI source to all resolution output for
troubleshooting.

Bypass means this device will maintain playing the original format of HDMI signals in video
and perhaps audio. By setting at this mode, the users may encounter compatibility issue
among different kinds of HDMI sources and displays. If you cannot get the audio and/or
video output normally at the system installation, please change the DIP switch setting to
default mode or even safe mode to verify the functionality of the device.
6
To learn the EDID of HDMI display for respective HDMI source devices, set (pin-1 and/or
pin-3) at ON[ª] first then connect the HDTV sets to respective HDMI inputs via HDMI cables.
Then please wait for 20 seconds for completing the EDID learning procedure. If you want to
learn the EDID from another HDTV, you must set pin-1 and/or pin-3) at OFF[©] first and
repeat this procedure all over again.

1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to retrieve and
provide DVI/HDMI EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden CAT5e 125MHz LAN cable and
ASTRODESIGN Video Signal Generator VG-859C.
3. The transmission length is largely affected by the type of LAN cables, the type of HDMI sources, and the
type of HDMI display. The testing result shows solid LAN cables (usually in bulk cable 300m/1000ft form)
can transmit a lot longer signals than stranded LAN cables (usually in patch cord form). Shielded STP
cables are better suited than unshielded UTP cables. A solid UTP CAT5e cable shows longer transmission
range than stranded STP CAT6 cable. For long extension users, solid LAN cables are the only viable
choice.
4. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, one can use
shielded LAN cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the LAN 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
LAN cables. For desired resolutions
7.
8. greater than 1080i or 1280x1024, a Cat-6 cable is recommended.
9. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input #1]
generally can produce better transmission performance among all HDMI inputs.
