Summary

Binary control spec for the Sharp/NEC PN-UN553V, derived from the Sharp/NEC "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). The device is controllable over RS-232C serial and over wired/wireless LAN (TCP). Commands are fixed-length hex frames with a trailing additive checksum (low-order byte of the sum of all preceding bytes). Covers power, input switching, mute groups, lens/shutter, picture/volume/aspect adjust, eco/PIP/edge-blend settings, and a large set of status queries.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source lists selectable rates: 4800 / 9600 / 19200 / 38400 / 115200 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source (communication mode = full duplex is stated, but is not flow control)

Traits

- powerable    # inferred from POWER ON / POWER OFF commands
- levelable    # inferred from VOLUME ADJUST / PICTURE ADJUST / LAMP ADJUST commands
- queryable    # inferred from numerous *REQUEST query commands
- routable     # inferred from INPUT SW CHANGE / AUDIO SELECT SET commands

Actions

# All payloads are hex bytes, verbatim from BDT140013 Rev 7.1.
# Framing: outgoing command frame = [cmdType] [cmdCode] 00h 00h [LEN] [DATA...] [CKS]
#   CKS = low-order byte of the sum of all preceding bytes (additive, mod 256).
# Response success frames begin 2Xh; error frames begin AXh with <ERR1><ERR2>.
# ID1/ID2 (control ID / model code) are returned in responses only.
# Where a command is parameterized, <DATA..> placeholders are shown verbatim from source.

# - POWER ON / POWER OFF accept no other command while the power transition
#   (including cooling time) is in progress.
# - error_status_request DATA09 Bit1 "interlock switch is open" is reported as an
#   error condition (portrait-cover / interlock). No explicit interlock procedure
#   is documented in this excerpt.
# UNRESOLVED: no explicit safety/interlock/power-sequencing procedure stated in source.

Notes

  • Command/response framing: outgoing frames begin with a command-type byte (0Xh); success responses begin 2Xh and echo <ID1> <ID2> (control ID, model code); error responses begin AXh and carry <ERR1> <ERR2>. CKS = low-order byte of the sum of all preceding bytes.
  • Error code table (ERR1/ERR2) is documented in section 2.4 (e.g. 00h/00h = unrecognized command; 02h/0Dh = command rejected because power is off; 02h/0Fh = no authority).
  • Serial is RS-232C cross-cable on the PC CONTROL D-SUB 9P port (pinout in source). LAN uses TCP port 7142 over wired (10/100BASE-TX) or optional wireless LAN unit.
  • Usage-time values update at one-minute intervals even though they are returned in one-second units.

Known Gaps

- "The source document is a generic Sharp/NEC projector command reference (BDT140013 Rev 7.1) and does not name the PN-UN553V model explicitly; the model name above is supplied from the entity metadata. Confirm this manual is the correct protocol reference for the PN-UN553V display."
- "Input terminal value codes, aspect values, eco-mode values, and sub-input values are referenced to an \"Appendix / Supplementary Information by Command\" that is NOT included in the refined source excerpt."
- "Outgoing command frames in this manual omit ID1/ID2 (control ID / model code); the full framing/insertion of ID1/ID2 into commands is not shown. Only response frames carry ID1/ID2."
- "flow control not stated in source (communication mode = full duplex is stated, but is not flow control)"
- "source does not document unsolicited notifications. All responses are"
- "source documents no explicit multi-step macro sequences."
- "no explicit safety/interlock/power-sequencing procedure stated in source."
- "Appendix \"Supplementary Information by Command\" (input terminal codes, aspect values, eco-mode values, base-model-type codes, sub-input codes) is not present in the refined source excerpt."
- "firmware version compatibility not stated."
- "whether PN-UN553V (a large-format display) actually implements all projector commands in BDT140013 Rev 7.1 is unconfirmed against a real device."
