Summary

Sharp/NEC NP Um361Xi Wk projector controlled via RS-232C serial or TCP/IP LAN (wired/wireless). Binary hex-frame protocol with a trailing checksum byte (low byte of sum of all preceding bytes). This spec covers the command catalogue from the Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # bps, all supported per source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: not explicitly stated (RTS/CTS pins present, full-duplex mode stated)
  duplex: full
addressing:
  port: 7142  # TCP, stated for LAN command send/receive
auth:
  type: none  # inferred: no auth procedure in source
# Frame format: <CMD bytes> <ID1> <ID2> <LEN> <DATA...> <CKS>
# Checksum = low-order one byte of sum of all preceding bytes.

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many status/information request commands present
  - levelable    # inferred: picture/volume/lamp adjust commands present
  - routable     # inferred: INPUT SW CHANGE command present

confirmation_required_for:
  - power_off  # blocks all other commands during cool-down
  - power_on   # blocks all other commands during warm-up
interlocks: []
notes: >
  Source notes power-on/off block other commands during transitions. No explicit
  safety interlock procedure, voltage/current specs, or fault-recovery sequences
  are documented in this command reference.
# UNRESOLVED: no dedicated safety/interlock section in source.

Notes

  • All commands/responses are hex byte frames terminated by a checksum byte (<CKS>), computed as the low-order one byte of the sum of all preceding bytes (see source example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
  • Frame structure: <CMD1> <CMD2> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1 is the projector's control ID; ID2 is the model code.
  • Success response prefixes mirror command group (2Xh); error response uses A Xh with <ERR1> <ERR2>. See source error code table (ERR1/ERR2 combos).
  • Lamp/filter usage times update at one-minute intervals despite one-second resolution.
  • For two-lamp models, lamp 2 (DATA01=01h) is valid in 037-4.
  • Input terminal enums, eco-mode enums, and sub-input enums reference an Appendix ("Supplementary Information by Command") not present in this source.

Spec done. 53 actions = every source row. Serial+TCP both populated. CKS frame + checksum rule in Transport/Notes. Enums missing (Appendix not in source) marked UNRESOLVED, no fabrication.

summary: "All 53 spec actions matched verbatim against source command reference; transport parameters verified; complete bidirectional coverage. (7 unresolved item(s) noted in Known Gaps.)"
```

## Known Gaps

```yaml
- "input-terminal value enums (Appendix \"Supplementary Information"
- "not explicitly stated (RTS/CTS pins present, full-duplex mode stated)"
- "enum in Appendix not present in source\""
- "no dedicated safety/interlock section in source."
- "Appendix \"Supplementary Information by Command\" not in source"
- "flow_control not explicitly stated (RTS/CTS pins wired, full-duplex stated)."
- "firmware version compatibility not stated in source."
```
