Sharp/NEC Pnm652 Control Spec

Summary

Sharp/NEC Pnm652 large-format projector controlled via RS-232C serial or wired/wireless LAN (TCP port 7142). Binary command protocol with hex framing and checksum. Source: "Projector Control Command Reference Manual" (BDT140013 Revision 7.1), covering power, input, mute, lens, picture/volume/aspect adjust, and numerous status/information queries.

Transport

Events

events: []
# UNRESOLVED: no unsolicited notifications documented in source. Protocol is request/response only.

Macros

macros: []
# UNRESOLVED: no multi-step sequences explicitly documented in source.

Safety

confirmation_required_for:
  - power_off   # cooling period follows; no other command accepted until complete
interlocks: []
# UNRESOLVED: source notes "interlock switch is open" as an error bit (009 ERROR STATUS DATA09 Bit1)
# but no interlock procedure or power-on sequencing requirement is explicitly documented.

Notes

Checksum (CKS): Sum all preceding bytes, take low-order 8 bits. Example: 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.

Frame structure: Command first byte identifies message class: 00h/01h/02h/03h = command; 20h/21h/22h/23h = ACK response; A0h/A1h/A2h/A3h = error response. Followed by command code byte, ID1 (control ID), ID2 (model code), LEN, DATA..., CKS.

Command acceptance: While power-on / power-off is in progress (incl. cooling), no other commands accepted (015, 016).

Usage time granularity: Lamp/filter usage time returned in one-second units but updated at one-minute intervals (037, 037-3, 037-4).

Picture/Sound mute auto-clear: Picture mute, sound mute, onscreen mute auto-clear on input/video signal switch; sound mute also clears on volume adjustment.

Spec written. 53 commands, all hex payloads verbatim. Serial+TCP transport (both documented in source). Draft/low confidence. UNRESOLVED markers for missing appendix, model code ID2, default baud, firmware range.

Known Gaps

- "model code (ID2) value for Pnm652 not stated in source; firmware version range not stated; appendix \"Supplementary Information by Command\" (input terminal values, aspect values, eco mode values, base model type values) not included in the refined source text."
- "appendix not in refined source.\""
- "no unsolicited notifications documented in source. Protocol is request/response only."
- "no multi-step sequences explicitly documented in source."
- "source notes \"interlock switch is open\" as an error bit (009 ERROR STATUS DATA09 Bit1)"

- "control ID (ID1) setting procedure / default not documented in refined source."
- "Appendix \"Supplementary Information by Command\" (input terminal values, aspect values, eco mode values, base model type values, sub input values, selection signal type values) not present in refined source — several actions reference it."
- "firmware version compatibility range not stated."
- "VOLUME ADJUST (030-2) source shows DATA01=mode in description but example byte order suggests DATA01=mode, DATA02-03=value; verify field order on real device."
