This FAQ describes some best practices for integrating Delta-enabled Solid State Logic consoles into existing computer networks.
When a user or facility’s IT dept wish to manage a network containing Solid State Logic consoles and DAW computers, there are certain factors to consider regarding how SSL's Delta Control software functions:
1: ipMIDI communicates between consoles and computers using multicast UDP with a destination address of 184.108.40.206.
SSL Delta Control communicates using multicast UDP with a destination of 220.127.116.11.
The remote software uses unicast TCP/IP for communication, and broadcast for console discovery.
2: Consoles are unable to send IGMP messages, so if your network has IGMP snooping running, you will need to create a static multicast group forwarding traffic with a destintation address of 18.104.22.168 and 22.214.171.124 between any ports where a console and its associated DAW computer(s) are connected.
Alternatively you can disable IGMP snooping on the ports to which consoles and DAW computers are connected.
3: If you have multiple consoles in the same facility, you will need to prevent multicast control data from one studio from being forwarded to other studios.
Failure to do this will result in all the studios controlling each other and the facility being unusable. You can either:
* Create ACL rules which prevent traffic with a destination of 126.96.36.199 & 188.8.131.52 between devices in different studios.
* Install one of SSL’s preconfigured LAN integration switches in each studio. These units contain a preconfigured static multicast group on ports 1-6 which will forward ipMIDI and Delta between any connected devices. Ports 7&8 are blocked from sending and receiving ipMIDI or Delta traffic, but will pass all other network traffic transparently.
4: If your DAW computer has more than one network adapter, you cannot connect one adapter to the console and the other to your building network and expect the system to work correctly with both adapters active.
The DAW computer will send broadcast messages through the default route – i.e. probably the one connected to your building network, so the console will be undiscoverable by the remote control software.
You should ensure only one network adapter is active on the DAW computer and connect that to other devices using a network switch.
