See a list of protocols in the Regulations and Standards topic.

The following are some details about each protocol that might be useful for setting up rules in network switches and routers.
MA-Net3
General Traffic
Transport layer: UDP - Multicast
Port number: 30020
IP addresses (default Base address):
- 236.4.1.0 - Administration group for all devices and sessions
- 236.4.1.1 - General communication (session data)
- 236.4.1.2 - Extended communication (session data)
- 236.4.1.3 - Extended DMX (session data)
- 236.4.1.4 - Reserved (session data)
Additional Information:
The IP addresses mentioned above belonging to the session are for session index number 1. Subsequent session indexes use different addresses using the formula "BaseIP+4*X" where "X" is the session index number, and "IP" is the address mentioned above. This only changes the last octet of the address.
So the default IP addresses specific for session index 3 are:
- 236.4.1.13
- 236.4.1.14
- 236.4.1.15
- 236.4.1.16
This allows for 32 sessions in a network.
Alternate Multicast Base
The default multicast base address (236.4.1.X) is within an IANA reserved block (according to RFC5771 - IANA Guidelines for IPv4 Multicast Address Assignments).
If this causes any problem in the network environment, then an alternative multicast base address can be selected in the Network Menu.
The option called Alternative uses the 239.4.1.X address as a base. The fourth number is the same as described above.
Alternate Traffic
Transport layer: TCP - Unicast
Port number: 30022+
Additional Information:
This is used when a station needs to send a lot of information to a different station, for instance, with a network update.
MA Worldserver
Transport layer: TCP - Unicast
Port number: 30021
Additional Information:
This must be routed to the Internet to access the official worldserver from MA Lighting.
MA Web-Remote - HTTP
Transport layer: TCP - Unicast
Port number: 80
MA Web-Remote - Websocket
Transport layer: TCP - Unicast
Port number: 8080
Art-Net (revision 1.4db)
Transport layer: UDP - Broadcast
Port number: 6454
and
Transport layer: TCP - Unicast
Port number: 6454
Additional Information:
In Auto-Mode, grandMA3 Art-Net will be sent as Unicast unless there are more than five receivers (default value in Broadcast Threshold) of the same DMX universe in the network. Then the protocol switches automatically to Broadcast.
The default Broadcast Threshold is set to five but can be changed in the Art-Net menu.
sACN
Transport layer: UDP - Multicast
Port number: 5568
IP addresses: 239.255.x.y
and
Transport layer: TCP - Unicast
Port number: 5568
Additional Information:
The default uses a Multicast address for each sACN DMX universe corresponding to a specific universe. The first two numbers in the IPv4 address are fixed. The two following numbers are calculated to match the universe number.
For instance, sACN universe 1 is on IP 239.255.0.1, and sACN universe 256 is on IP 239.255.1.0
PSN - PosiStageNet
Transport layer: UDP - Multicast
Port number: 65565
IP addresses: 236.10.10.10
Additional Information:
The Multicast address and port number can be changed in the PSN menu.
OSC - OpenSoundControl
Transport layer: TCP / UDP
Port number: 8000
Additional Information:
The transport layer protocol, address, and port number can be changed in the OSC menu.
NDI - Network Device Interface
mDNS communication
Transport layer: UDP - Multicast
Port number: 5353
IP addresses: 224.0.0.251
Alternate Discovery
Transport layer: TCP - Unicast
Port number: 5959
Base TCP Connection for Stream
Transport layer: TCP - Unicast
Port number: 5961+
UDP Shared with TCP Connections
Transport layer: UDP - Multicast
Port number: 5960+
UDP / TCP Receiving
Transport layer: UDP / TCP
Port number: 6960+
UDP / TCP Sending
Transport layer: UDP / TCP
Port number: 7960+
MVR-xchange
mDNS communication for discovery
Transport layer: UDP - Multicast
Port number: 5353
IP addresses: 224.0.0.251
MVR-xchange
Transport layer: TCP
Port number: 42424
Additional Information:
Only TCP exchange is supported at the moment. Learn more about MVR-xchange in the MVR-xchange topic.
SFTP
Transport layer: TCP - Unicast
Port number: 22
SNMP
Transport layer: UDP - Multicast
Port number: 161 and 162
Additional Information:
SNMP v1 and v2c. Public community.
AVAHI
Transport layer: UDP - Multicast
Port number: 5353
