Summary

Sharp/NEC PNM432 projector controlled via binary hex protocol over TCP (port 7142) or RS-232C serial (D-SUB 9P). Frames carry control ID, model code, and a low-byte additive checksum. Covers power, input switching, mutes, lens (shift/zoom/focus/memory), picture/volume adjust, eco mode, edge blending, PiP/PbP, freeze, shutter, and status/error queries.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source lists all five as configurable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: not stated in source (communication mode listed as "Full duplex")
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred from 015. POWER ON / 016. POWER OFF
  - queryable       # inferred from numerous REQUEST commands
  - levelable       # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST
  - routable        # inferred from 018. INPUT SW CHANGE

Actions

# All command/response payloads are hex bytes, verbatim from source.
# Frame legend:
#   <ID1> = control ID set on projector
#   <ID2> = model code (varies by model)
#   <CKS> = checksum = low-order one byte of sum of all preceding bytes
#   <DATA??> = variable-length data per command
# Response prefixes: 2xh = success (group code mirrors command group), Axh = error (with ERR1/ERR2).

Events

# UNRESOLVED: source describes no unsolicited notifications; all responses are replies to commands.

Macros

# UNRESOLVED: source documents no named multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks: []
notes:
  - "POWER OFF locks command acceptance during cooling period (see 016)."
  - "POWER ON locks command acceptance during power-on sequence (see 015)."
  - "Error bitfield (009) reports cover, fan, temperature, lamp, mirror-cover, foreign-matter sensor and interlock switch states; treat as health indicators, not safety interlocks to drive."
# UNRESOLVED: no explicit safety interlock procedures or power-on sequencing
# requirements stated in the source beyond the lockout notes above.

Notes

  • Binary protocol: every frame's final byte before <CKS> is summed; checksum = low byte of sum.
  • Response prefixes by group: success = 2xh mirroring command group; error = Axh carrying <ERR1> <ERR2>.
  • Lamp/filter usage time returned in seconds, refreshed at 1-minute granularity.
  • Many enum value tables (input terminals, aspect, eco mode, base model type, sub input) live in a referenced appendix "Supplementary Information by Command" that is not present in the refined source text.
  • ID2 (model code) varies by model — set from projector configuration; not enumerated here.

53 actions emitted (matches all rows in §2 command list + §3 detail). Unresolved marked for appendix enums, flow_control, firmware, ID2.

## Known Gaps

```yaml
- "appendix \"Supplementary Information by Command\" (input terminal enum values, aspect values, eco mode values, base model type values, sub input values) not included in refined source — several enum param ranges reference it."
- "not stated in source (communication mode listed as \"Full duplex\")"
- "appendix not in source).\""
- "source describes no unsolicited notifications; all responses are replies to commands."
- "source documents no named multi-step macro sequences."
- "no explicit safety interlock procedures or power-on sequencing"
- "appendix \"Supplementary Information by Command\" not in source — input terminal, aspect, eco mode, base model type, and sub input enum ranges unspecified."
- "firmware version compatibility not stated in source."
- "serial flow_control not stated (only \"Full duplex\" comm mode)."
- "ID2 model code value for PNM432 not stated in source."
