Accessing Cuemaster
On any device on the venue Wi-Fi, open a browser and navigate to http://<helm-ip>:3000/. The recommended operator station is a 10-inch or larger touchscreen tablet mounted next to the Bridge operator panel.
Show Mode
Cuemaster's default state. The topbar shows the Northstar mark, the product name, a live status indicator, the Helm IP, and an E-Stop button. Four tabs in the main area:
| Tab | Purpose |
|---|---|
| Overview | Stat cards (Nodes Online, Show Runtime, Active Alerts, Cues Fired) and recent activity |
| Cues | Every cue with its hat type, derived target, and a GO button |
| Nodes | Polaris board roster with IP, zone, firmware, last-poll age, status |
| Activity | Live event log — last 50 events |
Entering Maintenance Mode
Turn the maintenance key on the Polaris Bridge operator panel to the ON position. The Bridge firmware sends a UDP bridge-input event to HelmOS with role: 'maint-mode', value: 1. HelmOS aborts all running cues, broadcasts STOP to every node, and broadcasts a maintenance change over WebSocket. All connected Cuemaster clients swap to the amber Maintenance HMI within ~100 ms.
Maintenance HMI Tabs
| Tab | Purpose |
|---|---|
| Interlocks | Safety chain visualisation: E-Stop, Helm Online, TrueNorth Up, Min Nodes, Project Loaded, Zones Clear, Maint Key |
| Zone Diagnostics | Per-zone node count, average latency, fault state |
| Actuator Test | Manual fire buttons for individual outputs |
| I/O Status | Live HIGH/LOW state of every channel |
| Firmware | Bundle cards + OTA push controls |
Emergency Stop
Two paths, both immediate:
- Press the red mushroom button on the Bridge — physical E-Stop, fastest path
- Click the red E-Stop button in the Cuemaster topbar — software path, requires browser focus
Both abort every running cue and send UDP STOP to all Polaris nodes.
Loading a New Show
In Maintenance Mode, click ⬇ Load Show in the topbar. Drag a .nsss.compose into the modal. The new project becomes active. Cuemaster's Firmware tab will populate with the new bundle.
