Startup problems with USB485B

Recommended Posts

I have finally gotten a 16 plug unit, controller, and software, as well as a zillion lights and extension cords. I wanted to get the computer and FM transmitter set up and next week my kids will help me with the lights and connections.


I installed the software for the 485B and then connected it and then went to the LOR software hardware utility. When I first open the utility I get an error that says "The serial port assigned to LOR has a problem. Open of serial port has failed. Error 8002 invalid port number"
In windows system I can see the port (confirmed by unplugging and replugging the cable) but the auto configure under set up comm port says it can't find it. I have tried manually setting the port, changing the port in windows and trying again, uninstalling and reinstalling the drivers for the port etc. I have tried everything in every FAQ I could find and the LOR software cant find the unit.
HELP! I have hundreds of dollars in equipment and lights and I can't get past step one!

Hmm should be able to locate the comm port on it's own.

I assume you have rebooted after the install of the drivers for the USB485B.

You did follow all the steps for installation of the drivers?....As I recall there are like 2 or 3 items that have to be installed to make it work correctly.

I'm guessing you have a CTB16PC..

Try manually setting the com port field to 4. Connect the controller, click on ignore errors, and then select 1 on set new unit ID..

I believe I have heard of cases where the USB com port would not be recognized until after a controller with a programmed unit ID was connected...

Just checking a few things here: Windows still adds com4 when you plug in the adapter? Or the series I described above was done against the com port that was assigned to the adapter at the time?

At least the right half of the controller is powered up during these tests? The controller is cabled to the USB adapter? You have at least a blinking status LED on the controller? Does it go solid when the com port is manually set on the hardware utility?

Yes... I watched in the harware manager. It dissapears when I unplug it and reappears when I plug it in.

Yes. I even manually changed the adapter to a different port and tried again.... same result.

At least the right half of the controller is powered up during these tests?

Both halves.

The controller is cabled to the USB adapter?

The controller is cabled to the adapter.

You have at least a blinking status LED on the controller?

Blinking red light

Does it go solid when the com port is manually set on the hardware utility?


Nope..... stays blinking red

That message is because your PC is currently configured to play shows on a com port that your PC is not allowing the HW utility to open. You are not getting as far as the controller.

One other idea to check.. You don't have the LOR control panel running at the same time you are trying to use the hardware utility? Only one application can open the com port at a time...

The fact that you are getting an error on the open of the serial port can be caused by a couple of things.

But I want to confirm that you took the following steps from the trouble shooting guide.

1. Unplugged the USB Adapter from the PC

2. Downloaded and ran the FTClean per instruction in the guide.

3. Downloaded and ran the USB Driver Installer: http://www.lightorama.com/downloads/CDM_2.02.04.exe

4. Waited for the dirver install to complete, It takes a while and give no feedback until it is finished.

Then once those steps from the guide were completed...

5. Plug the controller into the USB adapter, power up the controller and then plug the USB adapter into the PC. (did you hear a bong or see a new hardware found message?)

6. Start the Hardware Utility (ignore any errors when it starts) and click the Auto Configure button.

I went back and did it again... just to make sure and basically got the same error. When I start the LOR control panel I get:

The serial port (com3) assigned to LOR has a problem.
You may need to select another port

Open of serial port failed
Error:(8002) Invalid port number
While: Executing Port Open Property

I reassigned the port to 4 in the windows control panel and try again... same problem.

Just for clarity, after the driver software finished installing, and you plugged in the adapter, and you launched the hardware utility, which gives the expected error, did you have everything plugged in, and try autoconfigure?

Separately, if you have the adapter installed, and you know the com port, are you able to use some other communications tool to successfully open the port? Not that you will get any response from the adapter, but it is a test to see if some software or setting on your PC is capturing the port and preventing LOR from using it..

If the port can be opened, then there is also a chance that the com chip on your light controller is bad...

Check to make sure nothing is grabbing your com port, and if not, then contact support to see what else they want to try before they investigate the light controller...

I'm not sure how I'd do that. Windows system tells me the port is functioning properly. When I manually reassign the adapter to another port (and I have tried 4 different ports) I continue to have the same problem
