Protocol Details

The grandMA3 system supports different network protocols.

Hint:
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:

  • 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 "IP+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 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.

Important:
According to RFC5771 (IANA Guidelines for IPv4 Multicast Address Assignments), the used Multicast addresses are within an IANA reserved block.
MA Lighting is currently investigating how to solve the issue.
For the current version of grandMA3 software, the exception needs to be made to accept the Multicast addresses in the local area network.

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+

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
