AI4AVSummary
Sharp/NEC NP-PV800UL-B1 laser projector (lamp unit 41ZL), controlled via RS-232C serial (D-SUB 9P PC CONTROL port) or wired/wireless LAN (TCP port 7142). Binary hex-framed protocol: commands prefixed 02h/03h, responses 22h/23h, request commands 00h with responses 20h, errors A0h/A1h/A2h/A3h with ERR1/ERR2 codes. Spec covers all 53 commands in the Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Actions
# Frame legend (from source §2.1/2.2):
# Command bytes shown verbatim; <ID1>=control ID, <ID2>=model code, <CKS>=checksum.
# Checksum = low-order byte of sum of all preceding bytes (incl. any DATA).
# Request commands (00h-prefixed) -> 20h-prefixed response with data.
# Set/adjust commands (02h/03h-prefixed) -> 22h/23h ack, A2h/A3h on error.
# Error response carries <ERR1> <ERR2>; see §2.4 error-code list (Feedbacks below).

# UNRESOLVED: source contains no explicit interlock procedure or power-on sequencing requirement;

Notes
- Binary protocol. All byte values in source given as hex (
NNh). ID1 = projector control ID, ID2 = model code (varies per model), CKS = low byte of sum of all preceding bytes. - Response prefixes:
20h/22h/23hsuccess (request/set/adjust),A0h/A2h/A3herror. - Two lamp slots supported on two-lamp models only (DATA01=01h Lamp2 in 037-4).
- Filter/lamp usage updated at 1-minute intervals though returned in seconds.
- Baud rate selectable among 5 values; source does not state a default.
- Wireless LAN via optional wireless-LAN unit (see separate operation manual).
Spec done. 53 commands enumerated verbatim, both transports (RS-232C + TCP 7142) captured, full error-code table in Feedbacks. Unresolved markers cover appendix refs, defaults, ranges, flow control.

## Known Gaps
```yaml
- "source is a generic command reference manual; literal \"NP-PV800UL-B1\" model string taken from device-name input, not from source body. Lamp unit 41ZL from device-name input."
- "RTS/CTS pins present (pins 7/8) but flow-control mode not stated"
- "absolute range not stated; query 060-1 DATA01=05h for bounds"
- "query 060-1 DATA01=00h for bounds"
- "query 053-1 per axis"
- "source describes no unsolicited notifications; all responses are solicited."
- "no multi-step sequences documented in source."
- "source contains no explicit interlock procedure or power-on sequencing requirement;"
- "firmware version compatibility not stated in source."
- "default baud rate not stated (one of 4800/9600/19200/38400/115200)."
- "ID1 (control ID) and ID2 (model code) default values not stated."
- "flow_control mode not stated (RTS/CTS pins present on D-SUB 9P)."
- "Appendix \"Supplementary Information by Command\" referenced for input-terminal values, aspect values, eco-mode values, sub-input values, base-model-type values — not included in this refined source."
- "variable value ranges (volume/picture gains) not stated; must query 060-1 per name at runtime."
- "voltage/current/power specs not in this control-protocol document."
