The lanbox has IP-adress 130.89.117.xxx / network mask 255.255.240.0, while my PC has 130.89.164.xxx and mask 255.255.224.0. I guess you have to be on the same subnet to make this work? Is it possible to just change the mask and gateway of the lanbox in global settings? I'm not an network expert so i have no idea if that will work..... Eh, I'd first want to know why the LanBox and your PC are on different subnets in the first place. This suggests to me they're connected via a router, however routers typically do not forward broadcasts, which would explain why it's not working for you. In normal setups you'd have the LanBox and the PC on the same physical and logical net. In the manual you indicate that turning UDP broadcast on generates up to 1 mbit/s of network traffic for 3072 transmitted channels. I presume that the load increases linear with the amount of channels you want to transmit? If that is true, is it possible to define a well restricted list of channels that has to be transmitted? For example: 1-24 + 100-120 or does it always has to be one range like 1-120? It always has to be a single range. Network load rougly increases linearly with the number of channels, though there is also some per-packet overhead. (the number of packets varies between 20 and 60 per second, depending on how many channels you broadcast). The figure of 1 mbit/s isn't quite right though.. the absolute max (dmx in, dmx out, external inputs, and 3072 channels of the mixer) is around 85 KB/s which is 680 kbit/s. Broadcasting only 120 channels of the mixer would be around 3.5 KB/s (28 kbit/s). -- Matthijs van Duin -- May the Forth be with you!
