Summary
BenQ M-Series projector RS-232C control protocol. ASCII command set wrapped in <CR>...<CR> (0x0D) framing using *key=value# syntax. Covers power, source selection, audio, picture, lamp, 3D, baud rate, projector position, standby behavior, and miscellaneous OSD/maintenance functions.

serial:
baud_rate: 115200 # default per source; switchable via *baud=N# to 2400/4800/9600/14400/19200/38400/57600/115200
data_bits: 8
parity: none
stop_bits: 1

type: none # inferred: no auth procedure in source
framing:
command_prefix: "<CR>" # 0x0D, see HEX example 0D 2A ... 0D
command_suffix: "<CR>" # 0x0D
payload_pattern: "*key=value#"
echo: true # source: each input character echoed; ready prompt 3E,00 after CR
idle_timeout: "5s -> echo 0D,0A,00"
Traits
- powerable # inferred from *pow=on/off/? commands
- routable # inferred from *sour=... input routing commands
- queryable # inferred from *...=? query commands
- levelable # inferred from volume/contrast/brightness/color/sharpness +/- commands

Variables
# Settable numeric ranges (contrast / brightness / color / sharpness / volume / mic volume) are
# accessed via +/- step commands listed in Actions; absolute range bounds are not stated in source.
# UNRESOLVED: numeric ranges (min/max/step) for vol, micvol, con, bri, color, sharp not stated in source.
Events
# Source documents synchronous echoes and error replies (see Feedbacks), but does not
# describe unsolicited push notifications.
# UNRESOLVED: no unsolicited event channel documented in source.
Macros
# UNRESOLVED: no multi-step macro sequences specified in source.
Safety
confirmation_required_for: []
interlocks: []
# Source notes operational constraints rather than safety interlocks:
# - "Unsupported item" / "Block item" replies are suppressed in power-saving mode (<1W standby)
# - Only status queries and *pow=on# are honored when projector is in low-power mode (<0.5W)
# - High Altitude mode (*Highaltitude=on/off) is exposed but no thermal-safety procedure stated
# UNRESOLVED: no explicit safety / interlock procedure stated in source.
Notes
- Command framing: every command is bracketed by
<CR>(0x0D) on both sides, e.g.0D 2A 70 6F 77 3D 6F 6E 23 0Dfor*pow=on#. - Echo behavior: input characters echo verbatim; query replies use uppercase command tail (e.g.
*POW=ON#). Ready prompt3E 00(> \0) is emitted after a bare CR; idle timeout marker0D 0A 00after 5 s of silence. - Error replies are bare strings (
Illegal format,Unsupported item,Block item) — no framing. - RS-232 DE-9 pinout per source: pin 2 = RXD, pin 3 = TXD, pin 5 = GND, pin 7 = RTS, pin 8 = CTS, pins 1/4/6/9 = NC.
- Both upper- and lower-case input accepted; case in echoed reply follows the source rule (query reply uppercased).
- Dual-lamp lamp modes (
dualbr,dualre,single,singleeco) only apply to dual-lamp variants — included for spec coverage; will returnUnsupported itemon single-lamp models. - Per the source: "The above function will be vary from model to model. (ex: source, audio settings, aspect ratio..etc)" — some commands may return
Unsupported itemon specific M-Series sub-models. - LAN-over-RS232 implementations forward the same command set when supported.
