DMX help to control lights

[stephan key]

So I bought the new USB to rs485 adapter and ther rj45 to XLR cable. running advance and 6.3 software.

I have a small dmx board and a light in 3ch mode. that works fine.

LOR in the test lights in DMX mode channel count at 3 and unit ID at 1.  all I get is jumping around colors that should not be happening.

what am I missing?

Jumping around colors like its cascading different colors through RGB??

No when moving the sliders. Lets say 1 is red, 2 green, 3 blue. Well none of that. Its anything but mostly full white.

56K is too slow for pixels

You only have 1 node (R,G,B)

Not pixels. Dmx LED stage lights

Never worked with those, but are they terminated  (120 ohms) at the last unit. RS485 (what that adapter does) is a terminated electrical protocol.

yep have one of those and it is in place. when doing all on it give me green. all off stays green.

You have it set up as a LOR reg network.

Add Network, Set Universe, say 1.

Set adaptor from dropdown, make sure it's the right one. Might be best to remove any other adaptors.

Adaptor Protocol Open DMX Raw.

Set your DMX starting address to 001 on the light or board.

Open test Channels and select UNI 1 and the first three channels should be your light

that works now! thank you.

but know the unit id is grayed out.  :(

 

[PhilMassey]

The unit ID only refers to a LOR network, The Universe is now roughly equivalent to the unit ID.

Each DMX fixture will have its own starting DMX address. For example if you have a second light, it would be set to start at DMX address 004.

Phil beat me to it.  You were trying to control DMX protocol devices using the LOR protocol (wrong data format).  Glad he got you working.

BTW, the devices out on that RS-485 serial network know absolutely nothing about universes.  That RS-485 serial network is the entire universe as far as those devices are concerned.  The concept of Universe numbers is only so that the computer software can deal with more than one DMX network.  When you start dealing in pixel networks using E1.31 (DMX over Ethernet - not to be confused with DMX over Cat-5), then there generally are multiple universes being carried over the E1.31 network.

The "Test Channels" dialog doesn't allow you to "page" through the available channels. If you want to test higher channel numbers in your DMX universe, you have to set the channel count to a bigger number (up to 512).

"Channel Count" changes only the number of controls in the "Test Channels" dialog.
