Well, Night before last all worked great, but then last night I turned on the laptop and opened the scheduler. When the show started we had sound but no lights. When I tried to set the output configuration I got the access to Com5 is denied again. After much fighting with it, I finally had to purge my show and create a new show file. The weird thing is that I recreated the same show using the same files and it ran great for almost 4 hours and then it just froze. I closed the scheduler down and opened it back up and it ran for the last hour just fine. Huh? Same music files and everything and I did not change anything between the two nights, so I don't get it. We are really starting to get busy and it sucks to have 10 cars lined up outside and not have any lights, so I went back to the latest 1.7 today and we are going to use that for the rest of this years shows. I really like the scheduler in the 1.8, but I will take reliability over features any day. I just ran a test with the 1.7 schedular and I have lights and sound, so I'm just going to stick with the old version for now.

Thanks for all your help!!

I'm a total newbie. .however, I had/have a similar issue with denied COM4 in my case. I'm only using 1 AC16 d-light controller which makes it even more maddening. I've shut down LSP and just had scheduler running on a Win 7 machine with the latest updates... It's a USB emulated COM port. I tried to reassign to other COM ports but that didnt help. I rebooted, cursed, clicked my heels and it did start to work again. But it's definately funky.. I also had my show die half way though (only 5 sequences, told ya, I'm a newbie!).. Anyway.. not sure if it's just me as a newbie or the software but it sure as heck drove me nuts.

On a related scheduler question.. I noticed that scheduler doesn't wake up a sleeping PC which stinks... Do I disable the power saving settings on my PC or is there some setting I configure in scheduler.. I couldn't find anything that was sticking out that was obvious (disable power saving features on PC?) I hate to leave the PC running at full tilt all day just to have it run my light show for a few hours in the evening. Any insight that can be providef would be much appreciated on both fronts.. Thanks!

Was there a fix for this?

I was doing some testing last night with a single AC16 using the D-Light USB dongle and the sequencer.

If I use the hardware test in LSP for the single AC16, it comes up with the denied access to COM4 port (nothing else is plugged in to the Comms port and I've verified that the dongle and drivers have loaded under the device manager).

If I use the D-Light harware test utility, it connects to the AC16 and I can control the lisghts on all 16 channels
Switch to LSP and it will not connect to the AC16 and reports denied access to COM4 port

I'm running it under Windows 7 and using the latest version of LSP.

Any ideas folks?

If you use the D-Light test utility after you close it down, unplug your dongle and then plug it back in so it will reset. Also make sure in your advanced power settings you don't have your USB ports going to sleep. Another thing I do is run LSP as an administrator which seems to stop a lot of little problems.

I figured it out today

I'm testing a single AC16 plus in the sequence I'm planning to use Pixel Net. Because I don't have the USB PixelNet dongle yet, I had to delete those controllers since LSP assumes the USB dongle should be connected which was interfering with the comms port for the D-Light AC16.

I followed the following proceedure

1. Delete all controllers that don't have a dongle yet
2. Exit LSP
3. Plug in USB dongle
4. Connect to the AC16 via the dongle and thr D-Light Hardware utility
5. Set it's baud rate to 57600 via hardware utility and it's address to 1
6. Disconnect
7. Exit utility
8. Restart LSP
9. Set baud rates in LSP to 57600 in the controller set up menus
10. Set controller address to 1
11. Click on the connect bulb
12. Hit play in the sequencer

Voila, all is well in blinky light world
