Bridge Operator Panel
Physical buttons. Real interlocks. No mouse required.
What it does, plainly.
Bridge is the operator's hardware panel. Five purpose-built buttons handle the entire show lifecycle — start, stop, reset, maintenance unlock, and server reset — with six LED indicators that mirror system state at a glance. It connects to Helm over USB serial, runs on bare-metal firmware with no external libraries, and continues to drive its LEDs even if Cuemaster is offline.
Hardware-first interlocks: Show Start refuses to fire while Show Stop is latched.
Maintenance keyswitch is physical, not a password. No software unlock.
Bridge keeps reporting button state and LED feedback even during HelmOS restart.
Custom button caps and faceplates available — specify colors and labels at order.
