Control Overview

Cognio Supports many methods of Control

  • Control Panel Groups
  • Presets
  • Control Linking
  • 3rd Party Lua Control Drivers
  • External Control of Cognio with JSON-RPC

Connections

Cognio devices are controlled over Ethernet. They do not have an RS-232 serial control port.

Third-party control systems connect using the Cognio Control Protocol, which uses JSON-RPC 2.0 over TCP. By default, a Cognio device listens for control connections on TCP port 3012, and each message must end with a null byte (\0). Before a control system can reach a control, you must expose it through a Control Panel Group with Remote Enable turned on.

Note

Cognio does not support the text-based Symetrix Remote Control Protocol used by Composer and the legacy Symetrix DSPs. UDP/TCP port 48631, numeric remote control numbers, and commands such as GS2, CS, and Q! are not available. To move an existing control system to Cognio, see Differences Between Cognio and Composer.

For setup, message format, and supported methods, see Using the Cognio Control Protocol.
