  • The original Rudolph did not have a red nose. In that day and age, red noses were seen as an indicator of chronic alcoholism and Montgomery Ward didn’t want him to look like a drunkard. To complete the original picture, he was almost named Reginald or Rollo.
  • The Christmas wreath was originally hung as a symbol of Jesus. The holly represents his crown of thorns and the red berries the blood he shed.
  • The three traditional colors of most Christmas decorations are red, green and gold. Red symbolizes the blood of Christ, green symbolized life and rebirth, and gold represents light, royalty and wealth.
  • Tinsel was invented in 1610 in Germany and was once made of real silver.
  • The oldest artificial Christmas trees date back to the late 1800s and were made of green raffia (think grass hula skirts) or dyed goose feathers. Next the Addis Brush Company used their machinery that wove toilet brushes to create pine-like branches for artificial Christmas trees that were less flammable and could hold heavier decorations.
  • ‘Jingle Bells’ – the popular Christmas song was composed by James Pierpont in Massachusetts, America. It was, however, written for thanksgiving and not Christmas.
  • Coca-Cola was the first company that used Santa Claus during the winter season for promotion.
  • Hallmark introduced their first Christmas cards in 1915.
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.

Rgb And Multiple Networks

Recommended Posts

I’ve heard that only so many CCRs can be on a single Network. I have 7 CCRs, programming aside, what exactly – network wise - is it I need to do to add these to my show. I know I can no longer use my MP3 – too bad, it was a great way to run a show.

LOR's software "knows" when it is dropping data as a result of the lack of bandwidth, I've always been suprised that LOR never put in a warning when a sequence hit that level. Personally I think you'll have problems running those CCR's with the LOR protocol when you hit complex commands.

This maybe of help in understanding why this happens:

Tim,

with 7 CCR's you'll probably want to use two (or maybe 3) LOR networks depending on how many other controllers you have. To do this you will do the following:

- PC with LOR software acting as the show player

- One LOR USB RS485 dongle per network (there are 3 flavors availabe)

- run the CAT5 from the dongles to your controllers

- use the LOR Control Panel and Schedule editor to run the show.

hope that helps,

dave

...- One LOR USB RS485 dongle per network (there are 3 flavors available)...

This is the part I'm confused about. Do I need to 3 network cards and/or USB, 1 for each LOR USB RS485 dongle?

Previously I controlled 7 CTB16PC with Cat 5 and several Easy Light Linkers using a LOR1602W, Can the CAT5 cable connections come from 1 of those CTB16PC/LOR1602W controllers or do they all have to come from a PC (another concept that is foreign)?

Tim,

you still wire up your controllers the same way. You can daisy chain them just like before, the only two things that really change are:

1. your show is run from the PC instead of your MP3 player

2. each network will run back to the pc (a network can be many daisy chained controllers/CCR's)

You would plug the 3 dongles into 3 USB ports on the computer.

For example

Network 1 = PC USB port 1 -> Dongle 1 -> CTB16PC -> LOR1602W -> LOR1602W... etc

Network 2 = PC USB port 2 -> Dongle 2 -> LOR1602W ->CCR - > CCR... etc

Network 3 = PC USB port 3 -> Dongle 2 -> CCR -> CCR -> CCR... etc

OK, now I am completely overwhelmed!!! How do you program for multiple networks? I know many of you have already crossed this bridge, so where are the How-To guides to set all of this up? I was going to buy a few more CCRs this summer, but now...

Tim,

the programming is exactly the same. You assign each controller to a network in the Sequencing software.

Start with the user manual: http://www.lightorama.com/downloads/3.0.2/LORHelp.pdf

On page 62 it introduces multiple networks and shows how for each channel the network can be selected (regular, aux a, etc) (note you can now do 16 networks i think)

In your S3 software go to the Tools > Channel Configuration menu and you will see a column called NETWORK. This column will show (and let you change) the network that each controller is set to.

Also, you manage the which network is on which dongle in the Edit > Preferences > Network Prefences menu.

There is a video posted by LOR on multiple networks that help with CCR's.. i have not watched it but it looks to cover the basics. http://www.youtube.com/watch?v=7XTiLH3J2Ss&feature=youtu.be

(found this on the LOR video tutorial list (http://www.lightorama.com/S3TutorialLinks.html)

Would using either USB-RS485 Isolated Adapter, or RS485 Network Repeater, or USB-RS485 Adapter with Booster help to run more CCRs per network?

Got some questions about this too as I am thinking about jumping in.

What do I do if my PC only has 2 USB ports?

I had 4 CCRs last season and ran into problems with too many commands on a single network.

A lot of white chases with fades going up and down.

So I am using one network for each CCR which is over kill.

For each network you need a USB adapter and make a change in the sequence editor.

Get a powered USB hub and it will work.

I'm Still a little confused, If I were to get a powered usb hub and hook up 5 networks to it wouldn't they all be on the same comport number? Or dosen't that matter, which compot number there on?

gmac,

each dongle(USB-RS485, etc) that you connect will get it's own comm port #, even if they are on a USB hub. Plug them in one at a time, let the PC detect it, then plug in the next one.

Aahh, That's where I messed up. I plugged in one, let the pc detect it, then unplugged it and plugged in the other one. The pc gave the 2nd one the same comm port #.

No - it doesn't matter what type of adapter you use - they are all still just RS485 adapters. This is a function of the speed at which the LOR protocol runs and the overall design of the protcol. The solution for excessive commands can only be solved with a faster network speed (not possible that I know of) or a method within the LOR software to warn you when there are too many commands for a given period of time.

Using a USB hub, powered or not, will make no difference. The only solution is to create additional LOR networks with addtiional 485 adapters. Ideally, you could switch to DMX running over E1.31.

One would think that DMX running over E1.31 would be quite a fast network, curious if anyone has tested how many CCR's this network can handle? Or how quick the command response times are. In the same thinking is the LOR network a Digital network or Analog?
