Barco Egpu Control Spec

Summary

Barco Pulse API control spec for the Barco Egpu projector. JSON-RPC 2.0 over TCP/IP on port 9090, or RS-232 serial at 19200 baud, 8N1, no flow control. Methods cover power, source selection, picture settings, illumination, warping, blending, environment telemetry, optics, DMX, and firmware management.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 9090
serial:
  baud_rate: 19200
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: optional  # inferred: source states authentication "can be skipped" for normal end user access; only required for elevated access levels

Traits

- powerable       # inferred from system.poweron / system.poweroff commands
- routable        # inferred from image.window.main.source (source selection) commands

Variables

# UNRESOLVED: section omitted - every settable parameter from the source is already represented as a dedicated action above (per the granularity rule that one named property counts as one action).

Macros

# UNRESOLVED: no explicit multi-step sequences described in source.

Safety

confirmation_required_for:
  - system_poweroff
  - system_poweron
interlocks: []
# UNRESOLVED: source recommends verifying system.state is "standby" or "ready" before poweron, and "on" before poweroff; not enforced as an interlock by the device. No explicit safety warnings, interlocks, or power-on sequencing requirements beyond this practice.

Notes

• Pulse API uses JSON-RPC 2.0 over TCP port 9090 OR RS-232 at 19200 baud 8N1. Same command set for both transports.
• Property parameters are passed by name (order does not matter).
• Best practice: wait for property.set confirmation before setting the same property again.
• "params" member may be omitted for methods that take no arguments; ignored if present.
• system.poweron / system.poweroff return null; errors come in error member.
• ECO-mode wake requires Wake-on-LAN (MAC address), physical power button, or serial :POWR1\r.
• Source-to-object-name translation: remove non-word chars, lowercase (e.g. "DisplayPort 1" -> "displayport1").
• File endpoint base URL: http://<address>/api/... (not the same as JSON-RPC port).
• API surface is dynamic: introspection is the canonical way to discover available objects/methods/properties/signals for a specific projector configuration.

Verification Summary

verdict: verified
checked_at: 2026-08-05T07:29:18.514Z
matched_actions: 86
action_count: 86
confidence: medium
summary: "All 86 spec actions map verbatim to JSON-RPC methods and endpoints documented in the Barco Pulse API catalog; transport parameters (port 9090, 19200 8N1) appear in source. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "device model \"Egpu\" not explicitly named in source; inferred from prompt context. Source actually titles itself as the Pulse API command catalog for Pulse projectors generally."
- "section omitted - every settable parameter from the source is already represented as a dedicated action above (per the granularity rule that one named property counts as one action)."
- "no explicit multi-step sequences described in source."
- "source recommends verifying system.state is \"standby\" or \"ready\" before poweron, and \"on\" before poweroff; not enforced as an interlock by the device. No explicit safety warnings, interlocks, or power-on sequencing requirements beyond this practice."
- "device model name \"Egpu\" not stated in source PDF; inferred from prompt. Source describes \"Pulse projectors\" generically."
- "firmware version compatibility ranges not stated."
- "voltage/current/power specs intentionally omitted (Tier 3)."
