Mac

Shutter PJ-OSC is a macOS utility that bridges OSC and PJLink projectors for theatre, live shows, and installations. Configure up to 10 PJLink projectors, each with its own IP address, PJLink password, optional name, and network interface. The app listens on one OSC port (UDP and TCP) and converts OSC routes into PJLink shutter and power commands. Shutter control supports per-projector routes such as /shutter/open/1 and /shutter/close/3, plus broadcast routes like /shutter/open/all and /shutter/close/all. Power commands are also available per projector or for all configured units. For security, Shutter PJ-OSC supports two password layers: PJLink password per projector (used to authenticate with each projector) Optional OSC password (to reject unauthorized OSC commands from untrusted clients) From the app interface, you can also control shutter and power directly with on-screen buttons and per-projector selection chips. A safety toggle helps prevent accidental power commands. The app shows per-projector status (connection and shutter open/closed/unknown), busy indicators while commands are in progress, and a built-in debug log with OSC activity and PJLink command/response details for troubleshooting.
