DVI connected to SiI151 PanelLink Receiver, so its an input card for something
RJ11 looks like serial console maybe
AMS1085CM-3.3  3.3V linear reg on a barrel connector, probably output?

cant get a hit in google

Custom lighting controller from this company would be my best guess: http://www.jollylighting.com/en/about.php

FCC id SV3 is Daesung Electric but I only see automotive stuff.

[Gribo]

The RJ45s have isolation transformers, Ethernet?

[ajb]

LED panel controller would be my bet.

The asian name for this is an "LED sending card"

Looking at that board it is clear that PCI provides power for it and a place to sit only. As is common with these LED panels, the video data comes in through the DVI port which is looped from the computer's DVI output and sent out to the panel through the RJ45s.

thank you amyk, ajb, ehughes

indeed pci was a red herring, it appears to be stand alone video converter


Fascinating, there are >10 manufacturers with their own custom clones of this design, using different FPGAs, different ram, different pcb layouts, but all sharing same origin and data standard, pretty cheap too.

Odd choice of URL

The PCI might be an option for controlling from a PC directly, or they just cloned a dev board and didn't bother removing that part. The same board with different firmware can be customised for different applications.

Those cards are paired with "LED Recievers"  (Asian Term)  a break out to HUB08 or HUB12 interface.     On the receiver side it is just a driver to control scanned LED matrix modules.      They are commonly used in large LED video walls.      The PCI does nothing.    The DVI is an input from another video card.   to get transmitted over CAT5 to the receivers.   

The cards usually come with some wonky PC software to get the DVI output to match the resolution of the LED matrix "wall".

Its definitely for something, clones based on Spartan 6 are PCIE x1, and I also found some Xilinx, and even dual FPGA vatiants. Im totally mind blown.

Looks like only 14 pins are connected, and at least 5 of those are ground on the one you posted initially.  It's likely only meant to provide power to the board, so that you can pop it into the same PC that's running your video wall content and use a DVI-DVI jumper from the video card to the panel controller card.

It is so you can install the card into the controlling PC and not need separate box. If you look closely at the PCI card edge, most of the contacts aren't actually connected to anything. The handful of contacts with connections are just ground, 3.3V and 5V. You still need to connect USB and HDMI with a short cable on the outside of the PC.

The PCIe version will be similiar setup.

That makes sense. Thanks guys
