For those of us who have a distance between the DMX source and the DMX end device, This is what I found.
Connected to the DMX wireless- works great to about 100' then signal interference comes into play and becomes hit or miss.
As far as a hard line connection, I have had no issues until about 300'.
A few dropped packets here and there, but nothing consistant. I tested the cable with my Fluke DSP_2000 cable certifier, and had a high signal loss at the far end. I cut and reterminated both ends with the same results.
I believe that this due to the proximity of the max data length of 328' being achieved.
I do not believe this would be an issue for most of us.
