Did you know?
  • 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.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

E1.31 Universe Assignment

Recommended Posts

Started to migrate my Mac software over to E1.31 (and will probably migrate to the public as well).  
One of the things I was wondering how useful it would be to have channel mapping.  How I define channel mapping is the ability to allocate a contiguous set of 512 channels from a sequence (not necessarily on any boundary), to a given interfaces universe (be it a usb dongle, E1.31 universe, etc).
 
In other words, instead of arbitrarily allocating on fixed 512 byte boundaries the channels to divide up on an E1.31 universe assignments, allow one to allocate the starting channel of their choice to an E1.31 universe.  This is useful if your pixel controller does not let you span a universe for a string. (of course, as with any flexibility, it also must be used carefully or can create issues for your network in terms of interpreting channel assignments).

OK Charles,

 

I understand IP networks, I understand DMX universes, and I understand E1.31. at least a little. If I follow you, you are talking about an E1.31 protocol using an IP address to define channels similar to a DMX universe. Is that correct?

No, I am lets say you have 8000 channels in your display.  Normally, Universe 1 would be channels 1-512, 2 would be 513-1024, snd so on.

 

 

However, you could also map whatever channels you want to those universe say Universe 2 is going to be channels 600-112. Just gives you some flexibility in how you sequence versue how your devices are configured.

OK, I think you need to see how Light Show Pro 2.5 lets you configure your channels. It sounds just like what you are describing.

If you go to here they describe it very well.  http://auschristmaslighting.com/forums/index.php/board,63.0.html?PHPSESSID=0c4ceffdc8bb639cd2f722027a523396

As far as the network is concerned each universe starts at channel 1 and finishes at channel 512, each universe will have its seperate iniverse number.

 

The way you configure in LSP is that each channel is individual, so i may have an element that starts at channel 2000 in LSP but then that start channel of 2000 and the channel range is then allocated (mapped) to a universe in the LSP E1.31 Application, each universe is still channel 1 to 512 but channel 2000 in LSP is mapped to the universe

 

This video in this thread will help you understand http://auschristmaslighting.com/forums/index.php/topic,2404.0.html

Yes, that is what I was assuming.  It is what many have allowed in terms of usb mapping.  Just curious how used that feature was used, as it was something I have in my E1.31 implementation.
