Summary

Sharp/NEC NP ME331X LCD projector controlled via a binary hexadecimal command protocol (document BDT140013 Rev 7.1). The device supports RS-232C serial control and TCP/IP network control (wired or optional wireless LAN unit) on TCP port 7142. Commands are framed hex sequences terminated by a modulo-256 checksum; responses use a success prefix (20h/21h/22h/23h) or error prefix (A0h/A1h/A2h/A3h) carrying ERR1/ERR2 codes.

Notes

  • Checksum rule (source 2.2): CKS = low-order one byte (8 bits) of the sum of all preceding bytes in the frame. Worked example from source: 20h 81h 01h 60h 01h 00h → sum = 103h → CKS = 03h.
  • Frame notation: commands/responses are hex series. <ID1> = control ID set on projector; <ID2> = model code (varies by model). <LEN> = byte length of DATA part. <DATA??> = variable-length data. <ERR1> <ERR2> = response error codes.
  • Response prefixes: success = 20h (no-data ack), 21h/22h/23h (data ack variants); error = A0h/A1h/A2h/A3h carrying <ERR1> <ERR2> <CKS>.
  • Picture/Sound/Onscreen mute auto-cancel: input terminal switch, video signal switch, or (for sound) volume adjustment turns the respective mute off.
  • Usage time granularity: lamp/filter usage time is returned in seconds but updated at one-minute intervals.
  • Error code list (source 2.4), ERR1/ERR2 hex pairs:
    • 00 00 command not recognized
    • 00 01 command not supported by model

## Known Gaps

```yaml
- "firmware version compatibility not stated in source."
- "specific NP ME331X model code (ID2) not stated; ID2 varies by model."
- "Appendix \"Supplementary Information by Command\" (input terminal values, aspect values, base model types, sub-input values, eco-mode values) not included in refined source."
- "RTS/CTS pins wired but flow control mode not stated in source"
- "appendix not in source).\""
- "full value list in Appendix 'Supplementary Information by Command', not in source).\""
- "value list in Appendix 'Supplementary Information by Command', not in source).\""
- "per-query structured feedback shapes (lamp/filter usage seconds,"
- "none identified beyond action-driven parameters."
- "source describes no unsolicited notifications / push events."
- "source documents no multi-step command sequences."
- "no explicit power-on sequencing procedure or voltage/current"
- "NP ME331X-specific model code (ID2) not in source — ID2 varies by projector model."
- "Appendix \"Supplementary Information by Command\" (input terminal values, aspect values, base model types, sub-input values, eco-mode values) not present in refined source text."
- "flow_control mode not stated (RTS/CTS pins wired per pin table)."
- "whether TCP port 7142 also applies to the optional wireless LAN unit — source defers to wireless unit manual."
