INTRODUCTION
The SP-5012 1x2 HDMI Splitter over Cat.X with Local Out 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.
The input HDMI source can be duplicated and distributed to 1 HDMI enable displays through cost
effective Cat-5/5e/6 cables with HDMI over CAT5 receivers (CV-735 and/or CV-715s). For convenience,
SP-5012 is also equipped a local HDMI output for monitoring. With the built in equalization, the input
HDMI cable can be extended up to 20 meters (66 feet) long under Full HD, and make the overall
transmission distance superior than regular HDMI splitters or matrix switches in the market.
FEATURES
●State-of-the-art Silicon Image (founder of HDMI) chipset embedded for utmost compatibility and
reliability
●Support HDMI Deep Color & 3D / DVI 1.0 compliant
●HDCP 1.1 compliant
●Regenerates the HDMI signal
●Supports audio output
●Supports default HDMI EDID and has the ability to learn the EDID of displays
●Extends up to 15m (50ft) of input HDMI cable
●Extends up to 15m (50ft) of output HDMI cable
●Extends up to 60m (200ft) (720p / 1080i) of output Cat.X cable
●Extends up to 40m (130ft) (1080p) of output Cat.X cable
●Minimizes the cable skew by adjustable 8-level equalization control
●Pure unaltered uncompressed 7.1ch digital HDMI over Cat.X cable transmission
●Allows cascading
●Perfectly integrated with other HDMI over Cat.X series products
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 RJ45 connectors is recommended.

Note for EDID (Extended Display Identification Data) learning
1If the HDTV shows video but without audio, please try to set audio mode to stereo.
2Factory default setting of Mode is pin-1 OFF []& pin-2 OFF []for 1080p with surround sound.
3If you encounter any unsolved audio/video output problem during system installation, please turn
any Mode to pin-1 OFF []& pin-2 ON []for safe mode to enforce the most compatible 1080p
stereo output for system check. However, the safe mode cannot be initiated if your HDMI source is
set to enforce 1080p output. In this case, please reconfigure your HDMI source to all resolution
output for troubleshooting.
4Bypass means the distribution amplifier 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 kindsof 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.
5To learn the EDID of HDMI display for respective HDMI source devices. Connect the HDTV sets to
the HDMI Local Output via HDMI cable, then set pin-1 at ON []. Then please wait for 5~10
seconds for completing the EDID learning procedure. If you want to learn the EDID from another
HDTV, you must set pin-1 at OFF []first and repeat this procedure all over again.

NOTICE
1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to retrieve
and provide DVI or HDMI display EDID information.
2. All HDMI over Cat.X transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
3. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI sources,
and the type of HDMI display. The testing result shows solid UTP cables (usually in the form of 330m
[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.
4. EIA/TIA-568-B termination (T568B) for category cables is recommended.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can
use double shielded STP cables to improve EMI problems, which is worsen in long transmission.
6. 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.
7. 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.
