BenQ BenQ E-Series RS-232 / IP control commands

Summary

BenQ E-Series projector RS-232C serial control spec. ASCII command protocol framed by <CR>...#<CR>, default 115200 8N1. Covers power, source select, audio, picture mode, picture setting, aspect, operation settings, baud, lamp, 3D, and miscellaneous controls.

Transport

protocols:
  - serial
serial:
  baud_rate: 115200  # default; settable via OSD to 2400/4800/9600/14400/19200/38400/57600/115200
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable       # inferred from power on/off commands
- routable        # inferred from source selection commands
- queryable       # inferred from query commands
- levelable       # inferred from volume/contrast/brightness/color/sharpness commands

Actions

# All commands are ASCII, framed as <CR>*cmd=args#<CR>.
# The <CR> framing is omitted from the `command` field below for readability;
# implementations MUST prepend 0x0D and append 0x0D to each command.

Feedbacks

# Source describes an echo protocol: each input character is echoed.

# Error responses: "Illegal format", "Unsupported item", "Block item".
# Power status responses (echo examples): "*POW=ON#", "*POW=OFF#".

Variables

# None documented as settable parameters distinct from the discrete action set.
# All settings in the source are addressed by discrete write commands, not free-form parameter sets.

Events

# Source describes unsolicited echo behavior only; no event subscription model documented.

Macros

# No multi-step sequences described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures, or power-on sequencing requirements.

Notes

Commands are ASCII framed as <CR>*cmd=args#<CR>. Implementations must prepend 0x0D and append 0x0D to each command string.
Echo behavior: each input character is echoed; on Enter (0x0D) the projector replies with > 0x00 (ready prompt).
Idle timeout: after 5s with no command, the projector echoes 0x0D 0x0A 0x00.
"Unsupported item" and "Block item" responses are not emitted in power saving mode (standby power < 1W).
Status and power-on commands are still functional in low power mode (< 0.5W).
Both upper- and lower-case input characters are accepted.
Volume bar display is supported.
If the system has Lan-over-RS232, the RS-232 command set remains supported.
Feature availability varies by model — sources, audio settings, and aspect ratios differ across E-Series variants.
* lampm =dual* and similar dual-lamp commands contain literal spaces as written in source; preserve verbatim.
Default baud 115200; can be changed via OSD or via the *baud=...# command (and may need to be re-matched on the host afterward).

Known Gaps

- "feature availability varies by model; source note states \"The above function will be vary from model to model. (ex: source, audio settings, aspect ratio..etc)\""
- "response format for other status queries not enumerated in source."
- "source contains no explicit safety warnings, interlock procedures, or power-on sequencing requirements."
- "firmware version compatibility not stated in source."
- "query response formats beyond power (e.g. source, picture mode) not enumerated in source."
- "voltage, current, power consumption not stated in source."
