Variables
# No continuous / non-discrete parameters documented beyond +/- step commands above.
# UNRESOLVED: absolute numeric setpoints for contrast/brightness/color/sharpness
# not stated in source; only +/- relative steps are documented.
Events
# UNRESOLVED: source does not document unsolicited device-initiated events
# over RS-232; all examples in the source are command/echo pairs.
Macros
# UNRESOLVED: source does not document any multi-step sequences.
Safety
confirmation_required_for: []
interlocks: []
# No safety warnings, interlock procedures, or power-on sequencing requirements
# are stated in the source.
Notes
- Every command is bracketed by
<CR>(ASCII 0x0D); the source's hex example for Power On is0D 2A 70 6F 77 3D 6F 6E 23 0D. - Each input character is echoed; for query commands the device additionally echoes
<CR>(0x0D) followed by the response, e.g.> *pow=?#*POW=ON#. - Idle prompt: pressing Enter returns
3E,00("projector ready to accept RS-232 command"); after 5 s of no traffic, device returns0D,0A,00. - Error responses:
Illegal format,Unsupported item,Block item. Items 5/6 are not supported in power saving (standby <1W). - Baud rate default 115200, settable in OSD to 2400/4800/9600/14400/19200/38400/57600/115200. Once baud is changed via RS-232 (
*baud=...#), host must reconnect at the new rate. - Source note: "The above function will be vary from model to model" — applicability of every enumerated row to MX520 specifically is not confirmed in the source. Treat as a generic BenQ projector command set; per-model applicability requires verification.
- Case-insensitive for input characters (per source note 2).

summary: "All 173 spec actions matched literally to source commands; all transport parameters (115200 baud, 8-bit, no parity, 1 stop bit, no flow control) verified in source; complete coverage. (5 unresolved item(s) noted in Known Gaps.)"
Known Gaps
- "applicability of every command to MX520 — source note states \"function will vary from model to model\" (ex: source, audio settings, aspect ratio..etc). The MX520-specific applicability of each row is not enumerated in the source."
- "absolute numeric setpoints for contrast/brightness/color/sharpness"
- "source does not document unsolicited device-initiated events"
- "source does not document any multi-step sequences."
- "firmware version compatibility not stated in source. UNRESOLVED: per-row MX520 applicability not stated in source. UNRESOLVED: network/IP-control command surface not stated in source (only RS-232 documented). UNRESOLVED: continuous numeric setpoints for picture settings not stated in source."
