CCB and some coloring problems


Chagoi

Recommended Posts

So, now that I have things up and running. I am noticing when going from a white cell then to a green cell, that yellow appears for a split second throughout the strand. This definately seems like a glitch as it varies from bulb to bulb each time and even the intensity of the yellow varies. I have checked my sequences, this is a single ccb device on a single network. Anyone else run into this?

Here is a sample of the sequence.

between the transition from the single white cell and the green 2 cell fade, many bulbs flash yellow.

i had it on average and changed it to short range faster. While this seemed to help, the same problem occurred....just faster/shorter if that makes any sense.

The only thing I can come up with is that the Blue pixel element is turning off before the Red pixel element (which would result in the yellow flash). Since you observed that the problem was reduced by changing the network to high speed, I would suggest that at least during that transition, the RS-485 network can't keep up.

I am assuming that for a hard transition like this, for each RGB pixel, the Red and Green pixel elements have to be commanded off individually. You did not tell us how many things are happening at the same time, but if for example, you have 6 CCRs (assuming NOT using macros, so each pixel is individually addressed) that have every pixel change from White to Green at the same time, you would have 600 commands trying to go down the RS-485 at the same time. SOMETHING is going to be delayed a bit.

As far as I know, we don't have any direct control over the order in which commands that should happen at the same time are sent down the wire. Normally it's not a big issue as the human eye works in milli-seconds so even at the relatively slow speed of the LOR RS-485 network, it all happens faster than the eye can see it. However there is a time lag. Try to cram enough data down the wire at the same time and something is going to give.

I would understand if that is the case, however, this is a single ccb on a network by itself. I have 3 ccb's and it happens on all of them when testing one at a time. I am sure if LOR tried this simple test, they would see the same. It does not happen to any other combination I have tried, only that specific one from what I have seen so far. If it is a glitch where blue is turning off in the rgb faster than the red, while in transition to ONLY a green fade, then that would be a bug that maybe could be corrected?

I did try to reconstruct it, but it still happened every time. Here is the channel expanded. This only occurs going from white to green. No other combination has this problem.

Chagoi,

I am still unable to reproduce your problem. I spent several hours last night trying different hardward configuration to see if a specific combination would cause this, but the sequence ran as expected.

If you havn't already, I would put in a support ticket with LOR.

I would try resetting the controller, but I found out last night that by holding down the reset button during power up, DID NOT reset my controller, all my setting were still there. I'm going to contact LOR about that and I'll repost here.

Chagoi,

The CCB manual states that "resetting the controller sets all parameters except the Unit ID back to the factory defaults" but LOR supports says the following:

Frank Farmer,

A Light-O-Rama help desk staff member has replied to your request, #587679 with the following response:

You're only reseting some low level parameters of the controller should the internal processor get confused. We leave all the user setting alone.

So I would still do a controller reset on your CCB controller to see if that resets any low level parameters that may have been corrupted, but you will not see any changes in the user configuration settings.

Frank
