BenQ RPxxxxK Series Control Spec

Summary

BenQ RPxxxxK Series interactive flat panel display. Supports RS-232 serial and TCP/IP control via LAN (port 8000) and HDBaseT. Command format identical across all transport layers. No authentication required.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 8000  # TCP port for RS232 via LAN (stated in source)
serial:
  baud_rate: null  # UNRESOLVED: configurable 9600/14400/19200/38400/57600/115200 bps; no single default stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable
- routable
- queryable
- levelable

Actions

Notes

Command echo responses: "Illegal format" (malformed command), "Unsupported item" (invalid for model), "Block item" (cannot execute under current condition).

Commands accepted in uppercase, lowercase, or mixed case.

RS232 via LAN: commands work with or without <CR> delimiters when sent over TCP. Over serial, commands are wrapped with <CR> (carriage return, 0x0D) at both ends as shown in the command table.

Source command table "Support" column indicates per-model availability for the MS531/BS5050/ES6540/MS521H/MX532/MW533/TW533/MH534/TH534 projectors; opcodes marked "No" are retained here where documented because they may apply to other models in the BenQ RS232 family.

Lamp dual-lamp mode opcodes (dualbr/dualre/single/singleeco) appear in source with irregular spacing (e.g. * lampm =dualbr#); normalized here to *lampm=dualbr# matching the rest of the lampm row family.

Upgrade done. Key adds:
- `command:` payload on every action (was zero — critical implementability gap)
- 7 new set/discrete actions: `mic_volume_adjust`, `standby_network_set`, `standby_microphone_set`, `lamp_saver_set`, `projection_login_code_set`, `broadcasting_set`, `amx_device_discovery_set` (all documented in source, missing before)
- 36 query actions (`kind: query`) — source Read rows, were only in Feedbacks
- 3 new feedbacks: `mic_volume_status`, `standby_network_status`, `standby_microphone_status`
- revision bumped 1→2, provenance note on source/RPxxxxK model mismatch added

Preserved: all original IDs, transport block, traits, feedback shapes.
