Hi Edward,
Yes to the network topography. To prove things out I have uplinked the network switch to a TP router to provide DHCP. Enabled DHCP and sACN on the desk and tested the remote app device control from a wireless phone link to the router. The network overview shows an ip 192.168.1.101 and an active remote connection when under control of the remote app. Unfortunately, the first line of the sACN readout is corrupted but shows a green tick and ends with 88FFDB7771001 the second line 'DMX 1Live, Univese1, Priority:100, Source name FlX S48 Universe 1'
The Smartshow is reconfigured to sACN 192.168.1.201 universe1 and this works fine with Art-Net controller phone app unicasting to 192.168.1.201 universe 1 using E1.31 so proved network links to from both the desk and the smartshow.
It's only a single universe license so all on 1
Regards
Paul
PS is the FLX S 48 PSU shipped probably around Autumn last year one made by sunpower 12v 3.33A, its suddenly occurred to me that a visiting group could have swapped it?
