I had a
bit of an odd ball question...
I planned on trying to use wireless
dmx for a different use.
DMX has 5 pins because they thought they would need it, and I have heard tales that you can run 2
DMX lines down one cable if you
wire it correctly. If that is all true, do wireless
dmx transfer 5 pins of information or 3pins? the reason I ask is because the project I need requires 4 pins of wireless digital data transfer.
Now right off the bat this may be a bad idea to try (due to data transfer rates and language issues ect), but I wanted to
throw that first question out there.
I guess as I write this, I figure it is also worth asking... is there a 4 wireless transmitter out there?
What do you mean 4
wire? Are you meaning 2 separate universes? If so, then no this will not work. All of the Wireless
DMX systems I have used (ShowDMX, WDMX, RC4) take in the data from 1
universe of
DMX, process it and use Xbee's or some other 2.4GHz
system to transmit the information, and reprocess it into a
DMX stream. For 2 universes you will need 2 transmitters, one for each
universe.
I recently built some
props that light up with
RGB LED tape, and I purchased 2 sets of Chauvet D-FI, for small devices there havent been any problems, but once I tried a 24
Channel device i noticed serious
lag between commands and the actual excecution on the
fixture.
All of my experiences with ShowDMX have been great. The rodent company uses them on most of their trucks for devices that need to be controlled weather they are foggers or
LED's. We had 3 transmitters, all transmitting 1
universe, and close to 30 recievers on different trucks,
props and drops. Never had any issues with
lag, or with being powered on and off endlessly during the shows.
RickR - Transmitting regular
DMX over Wifi is generally not a good idea either.
Ethernet and TCP/IP rely on packet transmitting, and
DMX doesnt like being broken up into the packet sizes that are used for TCP/IP transmission.
sACN and
Artnet can be transmitted over Wifi, but I would err on the side of caution with doing anything show critical with a setup like that as
ACN and
Artnet both transmit a large amount of information, and Wifi can be really unstable with consumer grade gear.
I have to shut off my Show Control wireless
router during shows, once the audience gets into the
house the number of smartphones that scan and hit the
router trying to connect even when it has a WPA password lags down the
router processor greatly, and I notice a large amount of packet
drop between devices.
