Yes all updated were applied to xp and lor. I thought that maybe it was crashing because I was also running zara radio, but it crashes with nothing running.:(

Hmm, well if it crashes with nothing running it has to be a system problem, If its having that many problems i would format it and reinstall windows. thats always the best way but the most time consuming to.

No I mean nothing besides lormonitor.exe. Without lor running computer stays up hrs. with it running if you cight click on the lor Icon in the task bar after awhile the status window crashes and hangs and you have to reboot to get it to quit.

Same problem happened to me last night (i had over 70 people here for the unvailing of this years new show, including local media and the charity we support/donate to). Weirdess this too, ran for almost 2.5 hours with out failure after that.

It happened again tonight 10 minutes into the show. Control panel still shows the show is running, but nothing, no sound and no lights. In order to regain control of the system, I have to perform a hard reboot and wait for it to come back up. Then of course I have to unplug and replug the USB485B adapter into the systems USB port so that the hardware utility will detect the controllers before enabling the show.

Last year was great (1.5.0), once the sequences were done, the show was created and scheduled, I never had to worry about being home to monitor the show. Looks like it will be a very long month here in western Colorado as I will become a homebody so that I can babysit the show.

Does anyone know if it is possible to run 1.5.0 with 3 controllers from last year running firmaware version 3.1 and two new ones ordered this year running 4.0 firmware? If so I might just go back to 1.5.0 until 1.6.9 becomes more stable. Dan, your thoughts?

Dan at LOR is great at replying quickly, so hang tight. In the meantime, I hope the guys at LOR have some fixes on the way...

I'm not up and running yet, heard a lot of good about it. Backup all your seq. then upgrade. If your not happy you can always reinstall 1.6

I too am experiencing this very thing. PC is a fresh load of XP fully patched Windows XP. I went through the process of removing the FTDI drivers for my USB serial adapter and re-installing the latest drivers. I am still experiencing a lights out condition in the middle of sequences, once the audio for that sequence ends, it stops the show. I have created fresh shows, and used different sequences within. The condition is totally random. I am running a 32 channel config with very 1.6.1, though I have tried 16.9 with the same results. Did not have this trouble last year.

Help!!

I suggest trying the 2.0.8 gamma LORII version. Its has been doing well. i have had no problems been running it every night and has not missed at all. You can always remove it and go back. just backup your sequences first.

My system (winXP, fast laptop) has been crashing requiring a reboot every 15 minutes to maybe several hours. since I've started my shows this year.

I'm running LOR 1.6.15 but had failures on 1.6.9 as well. and have updated all my firmware.

The problem is my USB485B. I don't know if it's defective or just not ready for prime time or perhaps should be used for linkers only and the manuals revised accordingly.

Here's the scenario; If I flip a 110v switch such as an outdoor light switch or better yet, unplug my transmitter and then plug it back in, my LORMonitor and LORTray go into the dreaded "not responding" mode and the only recovery is a reboot.

If you're using this adapter and think you have the same problem, run your show and then open Task Manager and look in the Applications folder. You should see the LOR apps running, Then start flipping power switches and see if you get a failure. There may be a 2-4 second delay before they start locking up.

I was able to crash my system even when all the controllers were off. (unplugged actually which may have made the diagnosis problematic since they were no longer grounded). The failure went away only after disconnecting both signal cables from this adapter. Either dead signal cable caused a failure.

I've had no failures, accidental or attempted, after switching back to my USB/Serial adapter.

Search on USB485B and you'll see my original symptom which, unfortunately, I later thought was a fluke and disregarded.

This adapter was originally designed to drive Linkers beyond 25 feet and for that purpose, could be perfectly fine but if used to drive a controller, be aware.

Well you might have something there because I am using the USB485B also and no matter which version of lor software I run, which drivers, or even which computer, (I also tried the kids computer and my laptop. Sorry Kids;) ) it crashes and requires a hard reboot to get going again .

It crashes with no rhyme or reason,it can go an hour ,or a whole show,or even 10 minutes but will not run from day to day.:(

My fix was to go back to a serial/usb adapter. If you don't have such an adapter, I can only suggest that you isolate the power the best you can to keep spurious electrical noise from the controllers and the adapter until LOR comes out with a fix or you order a serial adapter. Ideally different drivers for the adapter would be made available so one could tune the adapter for sensitivity.

Mine appears all too ready to pick up Aliens or Martians if they choose to transmit.

I just tested your your theory and as much as I wanted it to be just "your" problem, it appears you may be correct. My system hung and required a reboot. Probably not the best idea to perform such a test during the middle of the show with half a dozen cars out front!

LightORama Dan, what can you and/or LOR do to help and quickly?

I was having the same type problems and updating my software to LOR 1.6.15 AND updating my usb drivers did the trick. I've gone a week now with no problems (knock on wood). Before...I was only going a couple of days at best.

Hope this helps. Good luck.

I am running LOR 1.6.15 and my USB drivers for the USBRS485B driver is updated to:

FTDI
6/27/2007
2.2.4.0

The show still crashes/hangs. Is this not the correct and most recent driver?

Yes, it is. I read somewhere that someone had to uninstall LOR software, then reinstall original software they had...then update straight to 1.6.15. Luckily, I went from 1.6.3 to 1.6.9 to 1.6.15 with no problems (as of yet). You also might want to check your data cables to make sure they're a-ok.

I uninstalled all LOR software the USB drivers and ran the regwipe application and then rebooted. I installed 1.5.0 from CD and upgraded straight away to 1.16.15 and then upgraded drivers to the version indicated in prior post. The show ran perfect for the past 4 nights and then crashed unexpectedly tonight which brought me back to the message boards.

I stumbled across this thread, ran the test and sure enough, it crashed.

This USB problem apperas to be a combination of the USB drivers from FTDI and our software. We are not sure which is to blame but the result is that on some machines drivers/software hang. We are trying to come up with a solution but the problem is difficult to reproduce here... (it is obviously not hard to reproduce on some machines).

We are looking into the problem and trying to understand the exact error that is occuring and what can be done to prevent or handle this error in a way that the software does not hang.

The latest versions of the FTDI drivers seem to handle things better and reduce the occurance of problems but it is not perfect yet.

What can I use in place of the USBRS485B? My first LOR box is 95' from the PC running the LOR software. The 4 subsequent boxes are mounted right next to the first one.

Please see my previous posts for the following to make any sense.

I've done more testing since I can create the problem with little effort. (I also owe the LOR team a favor).

It does not fail on my desktop which has the same software and is almost identical hardware wise. Desktops are well shielded and grounded as opposed to laptops. It would seem like there's a RF problem with extraneous electrical noise that's picked up by the signal cables and then propagated to the laptop which can't handle it.

The failure occurs even when all electrical power is removed from everything (still grounded) and the laptop is running on battery or plugged in. My laptop and I suspect most or all others are not grounded through the power plug.

The failures occurred when I removed the FM transmitter power plug (transformer) and then reinstalled it. Interestingly, it failed less often if the speaker wire was disconnected between the two.

The other consistent failure occurred when I removed the power plug outside (about 6 ft away from the laptop) to the lights for my flag. This drives some electronics that control when the lights come on via a photo cell so this unit is capable of creating RF noise as well.

An electric drill caused a failure but not consistently. again, an electrically noisy device.

As I said in an old post, I first ran into this problem using a 1/4 hp motor.

I could not make it fail with a simple light (100 watts) turned off and on repeatedly.

I grounded the laptop and moved it away from the noise makers as far as the signal cable allowed (about 30 ft) and it still failed.

No, I didn't build a Faraday cage for testing.

It failed using the Sequencer or a show. I did most of the testing using the Sequencer for expediency.

It's hard to tell from most of the posts if a laptop or desktop was used during a failure.

Please signify which in future posts. If it only fails using a laptop, that might afford a workaround for those that don't have a serial adapter and have access to a desktop.

I am using a Dell desktop. I have everything sitting on a table in close proximity to each other (the monitor, the fm transmitter and the USB485 adapter). I also have a small radio on the floor next to the table.

Whenever I turn the switch off, you can here the popping noise through the radio over the music playing in the show. I am wondering if I should plug the FM transmitter into a different outlet from the rest of the equipment. Problem is I need it to be close to the computer for audio out connection.
