Connect to GrandMA 2 via Telnet

Telnet remote allows to control GrandMA2’s parameters such as Executors and Faders via Kratos using Actions. This can for example be used to manage the dimmer of fixtures automatically in function of the position of a Target or track people with LED bars.

Hardware connection

The Kratos station and the GrandMA2 station must be connected to the same ethernet network.

  • The Kratos station needs to have a ethernet address in the same subnet as the GrandMA2 station.
  • In case you use a physical GrandMA 2 console, the ethernet connection must be made via the Ethernet 1 (= eth0) connector (telnet will not go thru Ethernet 2 connector).

GrandMA side
