Summary

Sharp/NEC C651Q Avt3 projector, controlled via RS-232C serial (D-SUB 9P, cross cable) or wired/wireless LAN (TCP port 7142). This spec covers the binary command protocol documented in "Projector Control Command Reference Manual" (BDT140013 Rev 7.1): power, input switching, picture/sound/onscreen mutes, picture/volume/aspect/gain adjustments, lens and lens-memory control, shutter, freeze, eco mode, edge blending, PIP/Picture-by-Picture, audio select, and a full set of status and information queries. Commands and responses are hexadecimal byte frames with a trailing checksum byte.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source lists all five as supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # full duplex per source; RTS/CTS pins are wired (pin 7/8) but hardware flow control is not stated as enabled
addressing:
  port: 7142  # TCP command port per source ("Use TCP port number 7142")
auth:
  type: none  # inferred: no auth/login procedure in source

Traits

traits:
  - powerable   # inferred from POWER ON/OFF commands (015, 016)
  - queryable   # inferred from numerous status/information request commands (009, 037, 078, 097, 305, etc.)
  - routable    # inferred from INPUT SW CHANGE command (018)
  - levelable   # inferred from VOLUME ADJUST, PICTURE ADJUST, OTHER ADJUST gain commands (030-1/030-2/030-15)

Actions

# Common parameters for ALL commands (not repeated per action):
#   ID1  = control ID set on the projector (1 byte)
#   ID2  = model code, varies by model (1 byte)
#   CKS  = checksum: low-order one byte of the sum of all preceding bytes
#
# Response framing:
#   Success (no data):  2Xh <cmd> <ID1> <ID2> <LEN> <CKS>
#   Success (with data): 2Xh <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>
#   Failure:            AXh <cmd> <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>
# (X is the command-class nibble; see source "2.3 Responses".)

Notes

  • Command framing: every command/response is a hexadecimal byte sequence. The first byte encodes the command class (00h/01h/02h/03h for requests; 20h/21h/22h/23h for success responses; A0h/A1h/A2h/A3h for error responses). <ID1> = control ID, <ID2> = model code, <CKS> = checksum = low-order byte of the sum of all preceding bytes (worked example in source: 20h+81h+01h+60h+01h+00h=103h → CKS=03h).
  • Error responses carry <ERR1> <ERR2>; source lists ~25 error-code combinations (unrecognized command, unsupported command, invalid value, invalid input terminal, power off, no signal, forced onscreen mute, no authority, gain errors, etc.).
  • Serial cable is a cross (null-modem) cable on the PC CONTROL D-SUB 9P port (pin 2 RxD, 3 TxD, 5 GND, 7 RTS, 8 CTS).
  • Usage-time counters (lamp/filter) are readable in one-second units but updated at one-minute intervals.

Spec done. 53 commands enumerated (29 actions + 24 queries). All hex payloads verbatim from source. Gaps marked UNRESOLVED — appendix tables + firmware + model confirmation need operator follow-up.

Known Gaps

- "The source is a generic projector command manual; it does not explicitly enumerate the C651Q Avt3 model name. Model mapping assumed from the request. Firmware version compatibility not stated in source. Wireless LAN unit details not in source."
- "detailed bit-field decoding for error_status and full enum tables for eco_mode, input terminal, aspect, and sub-input values reference a source Appendix (\"Supplementary Information by Command\") that is not present in the provided refined source text."
- "enum values referenced in source Appendix, not present in refined text"
- "no explicit safety warnings or interlock procedures stated in the provided refined source."
- "(1) Source Appendix \"Supplementary Information by Command\" referenced for input terminal values, aspect values, eco mode values, sub-input values, and base model types is NOT present in the provided refined text — those enum tables cannot be populated. (2) Source is a generic projector manual; C651Q Avt3 model not explicitly named. (3) Firmware version compatibility not stated. (4) Wireless LAN unit specifications not in source. (5) Whether RTS/CTS hardware flow control is required is not stated (pins wired but mode listed as full duplex only)."
