Sharp/NEC UN552V Control Spec

Summary

Sharp/NEC UN552V display controlled via RS-232C serial (PC CONTROL D-SUB 9P) and/or wired/wireless LAN (TCP). Binary command protocol: each frame carries header bytes, control/model ID, length, optional data bytes, and a checksum byte. This spec covers the full command catalogue from the Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated (RTS/CTS pins wired per pin table but mode not documented)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable     # inferred: 015 POWER ON / 016 POWER OFF commands
  - queryable     # inferred: many *REQUEST commands return state
  - levelable     # inferred: 030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST, 030-15 OTHER ADJUST
  - routable      # inferred: 018 INPUT SW CHANGE, 098-198 PIP/PbP sub-input routing

Actions

# All command payloads verbatim from source (hex). <ID1>, <ID2>, <CKS>, DATA??
# are parameter placeholders per source §2.1/§2.2. Checksum = low byte of sum of
# all preceding bytes (source §2.2).

# Response frame format per source §2.3:

Variables

# Discrete settable parameters not already modeled as Actions are absent;
# all settable state in source is driven through Actions above.
# UNRESOLVED: appendix-referenced enum ranges (input terminal, eco mode,
# aspect, sub-input) not present in refined source.

Events

# Source documents no unsolicited notifications; all responses are solicited
# by commands (§2.3).

Macros

# Source documents no multi-step command sequences.

Safety

confirmation_required_for:
  - power_off          # source: during power-off incl. cooling, no other command accepted
  - shutter_close      # obscures output
interlocks:
  - "Power ON/OFF: no other command accepted while power transition in progress (incl. cooling)."
  - "Forced onscreen mute (ERR 02h/04h) can block command execution."
  - "Interlock switch open → extended error status DATA09 Bit1 (cmd 009)."
# UNRESOLVED: no explicit safety interlock procedures or power-on sequencing
# requirements stated in source beyond the command-acceptance notes above.

Notes

• Binary protocol, little-endian byte order for 16-bit values (low byte first).
• Checksum = low-order byte of sum of all preceding frame bytes (source §2.2 worked example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
• ID1 = control ID set on projector; ID2 = model code (model-specific, not enumerated in refined source).
• Response success/failure is encoded by the high nibble of the first response byte: 2xh = success, Axh = error (per §2.3 example and §3.x response templates).
• Lamp/filter usage times returned in seconds, updated at 1-minute intervals.
• Source is the generic "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). Some commands (lens shift, shutter, lamp 2, two-lamp models) may not apply to the UN552V display.

Spec done. 53 actions enumerated verbatim from source. Both serial + TCP (port 7142) emitted. All gaps marked `UNRESOLVED`. Status `draft`, confidence `low`.

## Known Gaps

```yaml
- "source doc titled \"Projector Control\" but applied to UN552V display; lens/shutter/lamp commands may not all apply to this model. Firmware version compatibility not stated. Input terminal value table (DATA01 of cmd 018, 319-10) referenced in \"Appendix: Supplementary Information by Command\" which is not present in the refined source."
- "flow control not stated (RTS/CTS pins wired per pin table but mode not documented)"
- "appendix-referenced enum ranges (input terminal, eco mode,"
- "no explicit safety interlock procedures or power-on sequencing"
- "ID2 model code value for UN552V not stated."
- "input terminal / aspect / eco-mode / sub-input enum value tables live in an Appendix not present in the refined source."
- "default baud rate among the 5 supported values (115200/38400/19200/9600/4800) not stated."
- "serial flow control mode not stated despite RTS/CTS pins wired in the D-SUB 9P table."
- "firmware version compatibility range not stated."
