 ====Main Hazards====
@@ Line 21: / Line 23: @@
   * Watch your retinas
   * Get a buddy to help you move it
+  * Don't attempt to reconfigure the led receiver or sender settings without knowing what you are doing, we don't have configuration files for this thing, if you overwrite whats there you will brick the display.
+==== Quick facts ====
+  * 256x224 resolution
+  * runs windows
+  * acts like a giant external monitor by mirroring a portion of the video stream
+  * its awesome.
+ ====Powering up the Video Wall====
+  * Plug in the cord on the left side of the screen
+  * Boot the computer
+  * Turn on the toggle switch beside the power cord to power up the main screen
+  * If the screen is powered but doesnt display an image, click the shortcut on the desktop for turn screen on and press the turn screen on button (you might have to toggle it if it thinks its already on)
+  * if the screen scaling looks off and the desktop image isn't lining up, go to display settings and set the screen to extend desktop, then back to duplicate desktop. Also check that the scaling is set to 100%
+====Playing a Game ====
+  * Turn on one or two wireless controllers by pressing the start button
+  * Fire up the NES or SNES emulator by clicking the link on the desktop
+  * Load a ROM - popular SNES selections are Mario Kart (racing), Mortal Kombat (fighting), Super Mario World (platform)
+====Displaying Anything else on the screen ====
+  * Simply drag whatever window you want to display to the magic square outlined in yellow on the desktop, that's it.
+ ====Disconnecting the Power====
+  * Turn the toggle switch off
+  * shutdown the computer
+  * unplug power

 Computer -> Sender Card -> Receiver Card -> LED Panel
-== Computer==
+=== Computer===
+  * Basic PC running windows. You also will need the XMPlayer Software to control the video wall. There is a magic portion of the screen marked out on the desktop that mirrors to the video wall. Drag whatever you want to display there.
+=== Sender Card ===
+  * DBSTAR - DBS-HVT11IN - Sourced from Aliexpress paid for by: 3bien,  DBynoe,  jon, Metal_Janet, mirong & packetbob
+  * Connects to the computer via USB (for control and settings) and DVI for video signal.
+  * Programmed to extract a potion of the video signal and send it to the receiver cards in each display panel
- ====Powering up the Video Wall====
-  *
+=== Reciever Card ===
- ====Disconnecting the Power====
-  * Due to inertia the motor will continue to spin for several minutes after being turned off, this could result in unexpected movement of the machine - **DO NOT REST YOUR FEET ON THE FOOT PEDAL WHEN THREADING THE MACHINE.**
+  * DBSTAR DBS-HRV09 S
-  * To render the machine safe, it is best practice to turn off the power to the motor, remove your workpiece from the machine, then press and hold the foot pedal until the machine stops moving.
+  * Came with the panels, preprogrammed with the correct configuration settings, we don't have the configuration file for these so don't overwrite it or you will brick the display.
+  * This card takes the data coming in from the ethernet link and shifts it out to the shift registers in the display panel.
+=== LED Panel ===
+  * 112x128 pixel RGB matrix panels 10-12mm pitch.
+  * contains 56 individual 16x16  modules - 7 modules wide and 8 high
+  * Can be mounted sideways
+  * has 3 - 80 amp 5v power supplies
+  * draws between 1 and 8 amps of 120v ac at full white depending on brightness level.
+  * LED Wall Features 4 of these.
+ ==== Setting password ====
+ DO YOU NEED THE PASSWORD FOR THE PARA SETTINGS?
+ READ THIS FIRST!!!!
+ YOU CAN DESTROY THIS DEVICE WITH THE WRONG SETTINGS
+ THIS IS NOT A JOKE
+ Rule 1. DO NOT CHANGE ANYTHING ON THE RIGHT SIDE OF THE PROGRAM ESPECIALLY SCREEN OPTIONS AND RECIEVER CARD AREAS
+ hitting apply will overwrite the current settings
+ which we do not have a backup for THEY ARE UNRECOVERABLE.
+ I spent over a month trying to recreate them using a spare reciever card
+ It did not work, DO NOT ATTEMPT TO FIGURE IT OUT WITHOUT FIRST TALKING TO @dbynoe, there is no recovery possible, YOU WILL DESTROY THE DISPLAY, no take backsies. I spent a lot of time to build this, a ton of hours figuring out how to make it work, and a bunch of hours, donated a decent chunk of cash to buy the sender card. DONT FUCK IT UP. thank you.
+ Rule 6. Limit brightness to below 20%, 100% will draw up to 30amps.
+ Rule 8: note that that you have been made aware of a very limited subset of the potential hazards contact @dbynoe on talk/slack if you really want to play with this.
+ Rule 10: the password is the numbers of the above rules in order, only change settings under screen display (brightness, but keep it under 20%) or output area of image
