Networking an ETC Ion with one network port

Hi all,

Theater maker/tech lead here. I've got a show that controls the ETC ION using OSC via Qlab. In most theaters, we've had Ions with 2 ethernet ports, and we use their secondary port for our cueing needs. An upcoming theater we're going to only has 1 port, but says "we do have a switch adapter that holds multiple ports."

I'm not quite deep enough on networking to know if this is trustworthy and will work. If they're using their only port for their "primary" house LX needs, does physically adding ports via a switch mean that we'll actually have a "secondary" port for our cueing needs?

I can change the IP address in Qlab so we're on the same network, but not sure if that's sufficient to give us the control we need.

Thanks in advance for any help!

  • No, this is necessary when you use more than one switch in the system.
    - IGMP snooping forwards the Multicast groups, which are used for sACN, to the other switches
    and also looks for wrong multicast traffic.
    - Spanning Tree is useful to avoid loops in the the network system which can crash the whole system.
    This can happen when there is a wrong patch connection.

    In this case it is not clear which network infrastructure is present.
