I am searching for the best way to send DMX commands to DMX-controllable lights at certain video time codes. There seem to be several options:
via GPIO (e.g. http://www.hms-electronics.com/BrightSign/data_sheets/gpio4_dmx4_r2.htm , limited to 4 channels?),
via serial port (e.g. http://www.hms-electronics.com/BrightSign/data_sheets/usb_s3_dmx.htm , limited to 50 channels?)
or maybe via UDP with an "unlimited" number of channels? Are there any DMX controllers that would directly accept UDP commands from a Brightsign player?
Which is the best way to control DMX-lights with Brightsigns?
I am pretty new to DMX so I don't really know how I need to configure the setup. We have DMX LED-Drivers that accept DMX signals via XLR or RJ45, but still no controller. So since I guess we can't directly send DMX signals via the RJ45 output of the Brightsign to the driver, but need to add a controller in between, I wonder which one to get?
As far as I know Art-Net is based on UDP, but we couldn't just connect a controller like the https://www.chauvetdj.com/products/dmx-an2/ and address the DMX channels, right? As little as a USB-connected controller like the https://www.enttec.com/product/lighting-communication-protocols/dmx512/dmx-usb-pro/ ? Both (and other similar DMX devices) would need to be configured by a computer and couldn't be used with the Brightsign, is that correct?
Would maybe this one work: https://allgeek.de/2018/07/22/professionelle-ethernet-dmx-bridge-udp/ ? (German language only). Or this one: https://www.acuitybrands.com/products/detail/1602874/pathway/pwinf-network-fade-processor/udp-to-dmx-din-mount-translator ?
I guess the HMS boards would work, but I rather look for a ready-to-use solution that don't need additional cases to be sturdy and safe in public spaces. Or are there no alternatives to the HMS boards?
Any help would be highly appreciated!
