I have received DMX LED drivers from a company called G&G in China, unfortunately with extremely poor documentation. This is how the drivers look like, under the picture are the specs:
The model I received is on the left, specs:
- 4 channel LED driver
- DMX512 3-pin interface (D+, D-, GND)
- 12-36V input
- 700mA constant-current driver
- "The refresh rate reaches 3980 Hz while guaranteeing the gray scale up to 65536"
With this information I was thinking that this was a 16bit DMX device (65536 levels)
The manufacturer says that these drivers will accept only 4 DMX addresses.
In my experience, to have 16bit control over LED channels, one should use two DMX addresses per channel, 256 values + 256 fine-tuning values
However, the manufacturer says that this is only true for an old version of the DMX protocol and that I should be able to control the drivers in 16 bit per channel using only one DMX address per channel, i.e. 4 DMX addresses per driver (the driver has 4 channels)
Has anyone here ever experienced the possibility of having 16bit control via the DMX protocol, using only one DMX address per channel?
