The discussion revolves around troubleshooting a Smartboard 580 cable issue after purchasing the board without necessary components. The user attempted to create a power cable using various power supplies but did not achieve the expected functionality. Despite following the schematic closely, they omitted safety components like the fuse, diode, and resistor, which may be crucial for proper operation. A suggestion was made to test with a known working power supply, as the board may be non-functional despite no visible damage. Voltage measurements taken from the board indicate potential issues, highlighting the need for further testing or professional assistance.

firstly hello.
second my problem is i bought a smartboard 580 (touchscreen dry erase board) at an auction. it came with nothing doing some digging i found a schematic for the cable required to connect the board to my computer: http://www2.smarttech.com/kbdoc/186" now i have tried to make this cable with 3 different power supply's. a 5v 550ma, a 9v 2.2a, and a 12v 1a. all of these are in the requirements set by the document except the 12v actually put out 16v but if you read the paper it says anything exceeding 18v just causes "noise". the only difference between there diagram and my cable is i left out the fuse,diode, and resistor because i figured these were just safety mechanisms so i don't fry the board. all the cables i tested didn't make the board light up like it should and the board doesn't appearer to be damaged at all(no burns, loose solders, or broken paths) as far as i can tell. now i am new to EE so i am somewhat ignorant but i wish to learn so ANY help would be GREATLY appreciated.thanx.
(takes a breath)

Unfortunately, your new auction purchase may be DOA. It's not necessary that there be visible damage to the electronics or printed circuit board for this to occur. If you know somebody else that has a (working) power supply for it, I'd try that out first.
 
unfortunatly i don't have an official power supply. is there any kind of testing i can do. oh and when i pluged into the board i measured the voltage across all the poart pins on the board and every other one starting with #1 had 8 volts to it (using the 9v power supply) not sure if this helps.

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
