Milwaukee..Chip Posted September 1, 2008 Share Posted September 1, 2008 Just wondering if the Units have to be daisy chained or if I can use both ports on the Little black box that comes from usb port to connect Cat 5 cable to.Has anyone tried this?

Denny Posted September 1, 2008 Share Posted September 1, 2008 Shouldn't make any difference. Check out this diagram. http://www.lightorama.com/LOR_Sophisticated.htmlIt shows the USB adapter connected to both a controller and the EZ light linker wireless. Should work just fine.

DavBro Posted September 2, 2008 Share Posted September 2, 2008 I hung two separate daisy chains off my box last year. One to each of the connectors. Works fine and it allowed the cable run to be a whole lot shorter, which is always a good thing.DavBro Link to comment Share on other sites More sharing options...
Richard Hamilton Posted September 5, 2008 Share Posted September 5, 2008 This brings the quesiton to mind....Is the LOR using a standard networking protocol?If so, I would expect that the controller is probably acting as a hub and probably makes no difference if you branch off both network connectors in the box to connect to other controllers or RF.I'm just speculating on this. I'll be interested in hearing from people with more brains on this than me. I'm laying out 16 controllers at a commercial venue and it is starting to get hairy.

I'm laying out 16 controllers at a commercial venue and it is starting to get hairy.Light-O-Rama uses RS485 which the the underlying electrical signaling and has pretty much been the standard for industrial control due in part to its high immunity to external electrical noise. On top of the RS485 is the standard serial protocol (start bit, data bits , stop bit(s).... ) Then on top of that is the "proprietary" (often copied!) LOR protocol.The RS485 layer does not recommend a configuration where there are branches. It works best with a single line. Now when you use both outputs of the USB485B you still only have a single line with the USB485B somewhere in the middle of that line.If you need to branch off you should use the LOR-REP repeater.Dan Link to comment Share on other sites More sharing options...
Richard Hamilton Posted September 5, 2008 Share Posted September 5, 2008 Ah! I understand perfectly. GREAT explanation. Link to comment Share on other sites More sharing options...
BrianNave Posted September 28, 2008 Share Posted September 28, 2008 Do you know where I can get the serial protocol (serial commands/strings)? I'd like to write some of my own applications using the LOR hardware. Link to comment Share on other sites More sharing options...
BrianNave Posted October 9, 2008 Share Posted October 9, 2008 Thanks for the reply... I have assumed that it was not coming after the long silence.Being a businessman myself I really don't understand NOT wanting someone to (possible) create a bigger demand for my product, but oh well.... reverse engineering time!

cattlefarmboy Posted October 9, 2008 Share Posted October 9, 2008 how about using the ELL and use the 2nd port for a controller has anyone done that before Link to comment Share on other sites More sharing options...
