Hi guys Im having a few problems with the following MO VFD Basicly ive set the VFD up connected to power and serial cable installed, once i turn on the computer the bars on the display slightly appear (Im guessing indication of power to the unit)! Windows fires up and i start LCDC auto detect the VFD and..... Cant find display?? try'd other software and no joy Im not to sure on COM ports so i havent really messed with them..Help whats my problem My rig is a SN41G
Hmmm... sounds like it might be a power problem. Verify that the power you have going to the unit is within spec. Check it with a multimeter, just to be sure. It is possible that after the system is operating (HD, fan, processor, etc.) the power supply dips the power too much so the VFD won't fully function. You may also want to try powering it seperately from the PC as a test.
Right havent try'd the multimeter as i havent got 1 so what i did do is, disconnect the DVDRW and Graphics card from my system and power with just the Mobo,Fan,HDD pluggin in and still the same screen up (Slightly filled bars) If someone can tell me which pins to connect on a PSU so i dont have to plug it into a motherboard i can test the unit on a 450w Enermax PSU cheers Jack
Strange, your title says LK202-25, that's a LCD. But you say it's a VFD? Anyway both models have a Supply Voltage of +4.75 to +5.25Vdc. So i think you HAD it connected at 12v, and now at 5v it works.
