SUMMARY

The discussion centers on troubleshooting a Smartboard 580 cable issue after purchasing the device at an auction without the necessary power supply. The user attempted to create a cable based on a schematic found online, using various power supplies (5V 550mA, 9V 2.2A, and 12V 1A) but did not achieve the expected functionality. Key components such as a fuse, diode, and resistor were omitted from the cable, which may have contributed to the problem. The suggestion was made to test with a known working power supply to determine if the board is functional.

PREREQUISITES
  • Understanding of basic electronics and circuit design.
  • Familiarity with power supply specifications and voltage measurements.
  • Knowledge of Smartboard 580 schematic and connection requirements.
  • Experience with troubleshooting electronic devices.
NEXT STEPS
  • Research how to properly construct a Smartboard 580 connection cable, including necessary components like fuses and diodes.
  • Learn about testing electronic devices using multimeters to diagnose power issues.
  • Investigate the specifications and compatibility of power supplies for the Smartboard 580.
  • Explore forums or communities focused on Smartboard repairs for additional insights and shared experiences.
USEFUL FOR

Electronics enthusiasts, educators, and technicians interested in repairing or troubleshooting Smartboard 580 devices, as well as anyone looking to understand the intricacies of connecting touchscreen technology to computers.

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.
 
unfortunately 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.
