Are you sure that will work? I've done multi-segment wireless DMX before and had to have each segment on its own, separate channel. Perhaps I'm not reading your post correctly.

No, I'm not positive at all. Here's my hope. Let's say I have lights (on all the same channel) at 100', 200' 300' .... the ones at 300' aren't getting a good signal due to interference and the fact that I wish to keep my antenna in the secured slot. I'd like to put a transceiver on my 200' light (DMX out) and see if it will send a wireless signal. I have no clue without testing this theory if it will work. I'm sure others here will be able to chime in whether it will or will not work. I really don't think it will ever be an issue, but just want to be prepared if something arises.
 
A benefit of the lights with transceivers instead of receivers .. they usually rebroadcast the signal .. getting more coverage.

I will add, on the multi-segment setup I did (see sample shots), I have both transmitters coming off my controller. Transmitter #2 was coming off the "dmx out" of transmitter #1. I imagine that if you hung transmitter #2 off the end of segment #1, and you put it on a different channel (feeding segment #2) it would work. I'm still fairly certain that if you have 2 transmitters, operating on the same frequency, it won't work right. Incidentally, FYI, on that setup I found that I could only run about 25 fixtures (with 6 ft dmx cables between each fixture) off a given receiver. I believe I also remember that the reason I went to 2 segments was that I had 2 different versions of of wireless units, which were not compatible. Seems I remember running 40 cans across the back of the stage (broken into 2 segments), then had 2 front sections (see the examples below) at the front of the stage, which were fed via transmitter #2. In other words, I had 2 receivers for each transmitter. Not saying this was optimal config but it's what I came up with, on the fly. The concert came off well and the producer was pleased with the lighting efforts.

Before the concert. Rear section has uplights against the back wall (even though you could barely see them due to the foil wallpaper). The ceiling is painted with SF Jr Zooms, shot from the floor. The bannister behind the band is non-dmx fixtures and the left-right front panels are dmx-controlled (wireless) via transmitter #2. In reflecting on this gig, the producer insisted the house lights stay up, full. This killed a lot of the punch I could have delivered, but that was outside my influence. For a first effort, I felt pretty good about it.

Just to clarify --- a transmitter and a transceiver are different.

I'm sorry (assuming you were talking to me), did I say "transceiver"? I meant transmitter and receiver. Of the units I own, each unit must be configured to be either a transmitter or a receiver. A single unit cannot do both at the same time. I would be curious to know if you could configure 2 transmitters on the same frequency, and have the receiving units to operate correctly. I nominate you to do the testing. lol
 
For clarification to others, a transceiver is a unit that can act like a receiver .. or like a transmitter .. or both .. transmitter +receiver = transceiver.

I didn't want him getting upset over "trans" .. might take the conversation in the wrong direction.

Yes .. it's great having lights that go both ways ..

For my Cube Echos, every light that receives signal from the transmitter then actually broadcasts that signal as well. So if i have a steady line of lights going across the room, theoretically i can go an infinite distance with each light continuing to broadcast the signal. I love this technology

I've got a note into my Rep to confirm that as well. From the way I read the manual, my lights do as well.

I would guess they probably do. One cool thing we've discovered also when doing lighting on 2 levels of a building is that we just ran one long DMX cable up to that second level into one of the lights and then let that light broadcast to the entire second chain of lights on that level. It's very cool what you can do with this technology. Then we'll use our lights on a stage and just let them receive the DMX signal and run a DMX cable out of the lights to feed DMX to our other fixtures on stage such as moving heads, scanners, ETC. I could go on and on about what i love about this type of fixture and it's capabilities.

Rick's got it right. While the term "transceiver" is used frequently in the world of wireless DMX, it's usually just lingo - I've yet to see a light that simultaneously re-transmits what it receives. Even the standalone "transceivers" are either-or, depending on whether or not they detect a DMX input signal.

Eternal CubeEcho fixtures are the same, according to the manual. In master mode, they transmit. In slave mode, they receive. They don't simultaneously receive and transmit.

If that's the case (and I'm not doubting you), would the first fixture on the upstairs segment be setup as a master (transmit)? I still am questioning this idea that a unit can act as both a receiver and transmitter, simultaneously. It really would be cool if they did make units where you had multiple transmitters all on the same frequency.

Hmmm, i wonder if I AM mistaken , lol. I'll look into it and get back to you. I know we have actually used the light as a transmitter before by running DMX directly into one light set to master and then having the rest in the room set to slave and that worked great. But as you pointed out, they wouldn't have been doing both at once.

I didn't say they did it at the same time, just the unit could do both. Instead of having to have different pcs.

My thoughts are that I can hook up my transceiver into one of the lights, coming out of the dmx out. I HOPE it then received the DMX signal from it's internal antenna and re-broadcast via the hooked up transceiver. Again .... I've not tested it and don't know if it works. Just hoping. ;) But, like I mentioned, I'll probably never need it, but would like to be prepared if so needed.

If you plug a transmitter into the DMX out then i don't see any reason it wouldnt work just fine
