How many CCRs will LOR handle?

Recommended Posts

How many CCRs will a single LOR system be able to handle? If I wanted to put 20 of them in my display, that would be like adding 3000 channels to my existing 180ish. Will I have throughput issues? Would I have to add additional USB adapters for more segments? Inquiring minds need to know...

Thanks a lot.

This is a very open question as there are a few things that can effect the bandwidth of the network when running CCRs

1: What refresh rate (timings) will you use to sequence with (50ms, 100ms etc.)

2: Will you be just using macros only and not actually sequencing the individual channels

3: Will all the CCRs be on at the same time

For me i had a general rule of no more than 4 to 5 CCRs per network, that way you guanantee that you shouldnt come across any network bandwidth issues, but on saying that you could get away with using all 20 CCRs in one network if you just used the macros or you could use more per network if your timings are not tight like 50ms or if the CCRs will not all be used at the same time. The best way is to play around and find the level that your happy with and then go with that. Not one solution here will suit all as some will get more per network.

My timings are typically .05 seconds.

2: Will you be just using macros only and not actually sequencing the individual channels

I had hoped to be able to use the superstar module of LOR when it comes out.

3: Will all the CCRs be on at the same time

At times, yes, all will be on at the same time, sometimes doing the same thing, other times, doing different things.

Another question - Suppose I have a bumch (say 10) CCR stripes running down the side of my house. If I use a macro that fills the CCR from one end to the other, and I start that macro on all 10 CCRs at once, will the macro finish on all 10 of them at the same instant? I guess the root of my question is, do the CCRs respond at the exact same rate to the same commands? This would be important if I were to program some chases running diagonally down across the grid of CCRs.

Thanks for your time.

I would tend to think so especially if using the same macro as the chip iniside the CCR sould all work at the same frequency , but im not 100% sure as i havent tested this but i would tend to think if there were any differences they would be very small and not really noticeable to the human eye.

I have 13 CCR's, and I use 2-USB485 network adapters
1 USB-485 for the LOR Controllers and the other is for the CCR's. I have had no issues with lag or false triggers on the CCR's

Thanks edvas69. I appreciate your time in answering me.

Assumptions and speculation and educated guesses are not good enough... I need cold hard fact. Maybe someone from LOR can answer my question about whether the CCRs operate in the exact same way, at the exact same speed, among a group of CCRs.

Again, thanks.

Last year I built 4 CCR matrix boxes and used mostly Macros with them. There were only a few times they got out of sync. So it does happen. But for my requirements it was close enough.
I sent the same chase macro and speed to all four and one would occasionally be a fraction of a second behind. It was always the same one too. So it may be correctable in the sequence, but I never got around to trying before I took them down.

Thanks for the replies Jeff and Bob. I wish I could take you up on your offer, Jeff, but I'll be in Wyoming then...

Dave... I asked this very question last year at the NJ Epic and Dan wouldn't answer.

I know that Brian Bruderer with the Super Star Editor has made some nice sequences with 12 ribbons. He puts 6 ribbons per network. LOR supports 16 networks so that would be 96 ribbons. We have never tested that but we have run 32 ribbons on 4 networks and had no issues.

Dan

EDIT: I had a typo above. It was was 32 ribbons on 6 networks... 5,5,5,5,6,6

Great so where do I get this software ; )

Only the demo version is available. It is being incorporated into the new LOR S3. http://www.superstarlights.com/

So what do I need to run 3 networks? 3 USB adapters plugged into 3 differnt USB Ports?


That is correct. I would suggest USB Hub with a power supply That way you only use one USB on the PC and the Hub will supply the power to the adapters.

Now my next question is which adapters would you suggest? I currently plan to deploy 18 CCRs but am also thinking of adding 10 (possibly) CCBs?

The USB485B would probably do the job just fine. I can't see a reason why you would need the USB485-ISO.

Has anyone got any idea how many CCR's one of the MP3 Show Director stand alone modules can drive please? My control net is remoted from my PC network far enough that I dont use a PC to drive the show.

Reading this thread has me a little nervous as I had intended to run 4 CCRs plus my ~200 normal channels off the show director. However, I now wonder if I am going to push it too far? (I dont really want to go to a PC driver solution for a number of logistical reasons).

I have an update to this question of the CCR macros getting out of sync. I found the settings on the one which was going faster were not the same as the other 7 ccrs. The internal speed was set to 9. All the others had 8 which is normal speed. This change back to 8 has resolved my problem and now they all move at the same speed.

I am planning to have a total of 8 CCR's and 11 CCB's in the near future, along with six 16-channel controllers. I understand from this thread that I'll need to break it down into around three if not four networks. Can I use the Easy Light Linkers for each network, without one interfering with the other, and still maintain the speed I need for .03 to .05 second timings? Is there a minimum spacing requirement between ELL transmitters?

Dan,

Would using one USB out of the computer be sufficient? Is the USB speed sufficient to handle 4 USB networks coming out of the USB hub? Just wondering....thx!

USB 1.1 can go up to 12 Mbit/s. USB 2.0 can go up to 480 Mbit/s.

The highest possible speed for an LOR network is 115.2 Kbit/s.

So yes, the USB speed is sufficient to handle more than the maximum 16 networks.

Wayne,

I believe that essentially all the usb ports on a given computer are basically set up as a hub anyway. I may be wrong with this, If I am wrong I hope someone will correct me. Dan has stated in the past. If you are going to use a usb hub, then it NEEDS to be a powered hub.
