Summary

Control spec for the Sharp/NEC LED Q039E2 projector (document BDT140013 Revision 7.1, "Projector Control Command Reference Manual"). Covers RS-232C serial control and TCP/IP LAN control (port 7142). The protocol is a binary hex-byte command/response scheme with a trailing checksum byte.

Transport

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

Traits

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

Actions

# All command payloads are verbatim hex bytes from the source. CKS = checksum byte
# computed as the low-order 8 bits of the sum of all preceding bytes (see Notes).
# <ID1> = control ID set on projector; <ID2> = model code (varies by model). Both
# omitted from the `command` field below where they are positional response fields.

# Source notes that during POWER ON / POWER OFF (including cooling time) no other

# documented.
# <!-- UNRESOLVED: no explicit safety warnings, interlock procedures, or power-on
# sequencing requirements stated in source. -->

Notes

  • Checksum (CKS): sum all preceding bytes, take the low-order 8 bits. Example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Frame format: commands begin with a message-type byte (00h-03h for requests; 20h-23h success responses; A0h-A3h error responses), followed by <ID1> (control ID set on projector) and <ID2> (model code, model-dependent), then LEN, then DATA bytes, then CKS.
  • Power-on/off blocking: while POWER ON is executing, no other command is accepted; while POWER OFF is executing (including cooling time), no other command is accepted.
  • Lens drive: after sending 7Fh (+continuous) or 81h (-continuous) in 053 DATA02, lens can be stopped by sending 00h. While lens is driving, the same command can re-issue without a stop.
  • Usage-time resolution: lamp/filter usage time returned in 1-second units but updated at 1-minute intervals.
  • Signal list number: returned value is 1 less than the practical number; add 1.
  • Error codes: ERR1/ERR2 combinations cover unrecognized command, unsupported-by-model, invalid value, invalid input, power-off rejection, memory errors, no signal, etc. (full list in section 2.4 of source).

53 actions, all command bytes verbatim. Checksum + frame docs in Notes. Appendix value tables + default baud + flow_control marked UNRESOLVED (not in refined source).

## Known Gaps

```yaml
- "this manual is a generic Sharp/NEC projector command reference; device-specific parameters (input terminal values, aspect values, eco-mode values, base-model-type codes) are deferred to an \"Appendix: Supplementary Information by Command\" that is not included in the source text."
- "flow control not stated in source (RTS/CTS pins wired in pin table)"
- "no explicit safety warnings, interlock procedures, or power-on"
- "device-specific value tables referenced as \"Appendix: Supplementary Information by Command\" (input terminal values, aspect values, eco-mode values, base-model-type codes, sub-input values) are not present in the refined source text."
- "default baud rate not stated (only the supported set 4800-115200)."
- "flow control not stated despite RTS/CTS pins being wired."
- "firmware version compatibility not stated."
- "wireless-LAN unit details deferred to a separate operation manual."
