INTRODUCTION
The SP-5128 2x8 HDMI Splitter with EDID Manager allows you to distribute one of the two
HDMI/DVI video sources up to 8 separate HDTV displays including one remotely cascade output via
Cat-5/5e cost effective cable. This splitter offers the most flexible solution by which the high definition
video and high quality audio can be transmitted to different local locations through HDMI cables and also
to the next stage over a long distance without degrading the quality. The cascade ability allows pure
digital video and audio broadcast station by station and therefore make extending HDMI compliant video
and audio anywhere feasible.

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.

3.Remote Control: Control signal
4.Rotary Control: Adjust the 8-level signal equalization control to the received HDMI signals. The HDMI
signal level varies from 0 (strongest) to 7 (weakest) for respective transmission length from longest
possible range to short distance. Dial the Signal Level from 7 to 0 and stop turning the rotary switch
whenever the audio/video is playing normally. Inappropriate signal level setting may cause
overpowering issues that would shorten the product's life significantly!

ROTARY CONTROL
In order to adapt the CAT5 cable, SP-5128 offers 8-level equalization control on the received
HDMI signal level. 0-to-7 = strongest-to-weakest signal level for respective transmission
length [long to short]. It is recommended to switch from 7 to 0 to find the optimal visual
experience.

EDID LEARNING
1. Power up the SP-5128. Connect to HDMI OUT 7 with the display you want the SP-5128 to learn its
EDID.
2. The SP-5128 is only bound to learn the EDID from the display for the HDMI source device connected
to HDMI OUT 7.
3. To learn the display's EDID for source device connected to HDMI OUT 7, Set SW1 to Right Position.
Power on and wait for about 5 seconds to complete the EDID learning process.

NOTICE
1. If the DVI or HDMI device requires the EDID information, please use CV-1001 or CV-5005H EDID
Reader/Writer to retrieve and provide DVI or HDMI display EDID information.
2. All HDMI over CAT5 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 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.
4. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 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 category 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.
