Well, after extensive testing I can report the following: I have four different display units hooked up to a p5wd2 premium ASUS board. All four units work fine, unless I connect a fan to one of the fan headers. Then I get random display corruption (about every five minutes), and once a day on ...

Well I could do that, but that would defeat the whole purpose of the fan control gpo and temp control gpo. I guess I'll just live with it, maybe wrap the usb cables to try to insulate the noise.

It seems the units are sensitive to electrical noise, so I'll try to isolate them as best as possible ...

The one unit, an MX4, has four fans and a floppy connected to it. This is the unit that shows the most interference in display characters and backlight problems.

Oh, and all four of my units are Rev 1.1 (more noise tolerant I have been told.)

Well I hooked up three units directly to the mobo (skipped the hub), reset the ports, reloaded the drivers. Let them run for an hour and they didn't shut down or turn the backlight off. However, I get garbled characters on one of the displays fairly often, and sometimes the events I program in LCDC ...

Hi Tom. Yes, all three boards are Rev 1.1. It must have been just that one fan then. Thanks for the info.

Hi Tom. I meant to say it was plugged into the hi power gpo number 4 (not 7). I have used several of these units, and this one particular several different fans into the fan headers. gpo 3, directly above this one had an identical fan (less than 4 watts). Specifically I wondered if the unit has some ...

Hi. I have an Mx414 and when I plugged a 3.84w Delta 60mm fan into gpo 7 (hi power), the display started flashing on and off, and the fan rpm was erratic.

I had the same fans plugged into 5 and 6, no problem. Yes I do have the unmodified floppy power cable plugged in.

From other posts it seems ...

Hi Tom

I'll get you that revision number when I get home tonight. Last night I hooked up two units and put them on the "relight the unit" routine. (Just to see if it works. Didn't see anything strange and let it run an hour (short for time)). Tonight I will take the routine off and just let them ...

What if I set up an event in LCDC to turn the backlight on after, say, each time a certain screen displays? Might not work if the unit has actually stalled, but if its still running, it might relight? Just a thought.

The internal cable definitely generated more errors. Probably closer to interference generating electronics that the outside routed cable. I use an open box tower Lubic case, so I just route the cables anywhere I want.

Dont think its a cable issue however. I have the unit grounded to the PSU ground ...

Hi Tom.

Tried both, internal and external, long and short ones.

Well still having a few problems. I have no less than four different MO displays (mx414, 411, 412, 212)I have tried on two ASUS motherboards. (I use all Delta fans, great quality, and no other lighting, like CCFl).
It is more stable now, but even after a fresh o/s install, removing all other usb ...

First, I want to thank you for your efforts. It is clear you have great dedication to your products.

I left both units on over the weekend (two different ASUS boards, one with an MX2 and the other with the MX4) I moved the one on the MX2 three feet outside of the case, away from any EMI, and I ...

Thank you for your efforts. I will await your reply. In the meantime I am going to remove the unit from the pc and try to set it up somewhere away from it. Perhaps there is some coincidental anomoly that affects the USB connection, when the unit is in proximity. and the LCDC software is running. I ...
