Gateway 4 can merge two streams of data to a DMX output. Depending on the settings, merge can operate as HTP/LTP or Priority.
In HTP (highest takes precedence), the levels of each channel in the two streams are compared and the highest value is used.
In LTP (latest takes precedence), the levels of each channel in the two streams is compared to the output; if there is a change, that level is output.
In Priority, the sACN Priority field defines which universe will be output.
Merging can operate with both unicast and multicast data.
If two streams from different IP addresses are directed to the same universe, the priority field is checked and the stream with the highest priority is output. If the priority field in both streams is identical, merging will occur.
If additional stream(s) are directed to the same universe, any additional stream with higher priority will take precedence. If the priority is identical to the merging streams, it will be ignored.
