Summary

Sharp/NEC NP V302H DLP projector controlled via binary hex frames over RS-232C (PC CONTROL port) and/or TCP/IP (LAN). Source is the vendor "Projector Control Command Reference Manual" (BDT140013 Revision 7.1) documenting 53 commands: power, input switch, mutes, picture/volume/aspect adjust, lens control and memory, status queries, eco mode, PIP/PbP, edge blending, and identity requests.

Transport

protocols:
  - serial
  - tcp  # both connection methods documented in source; per-model availability in Appendix (not in source)
serial:
  # RS-232C, D-SUB 9P "PC CONTROL" port, cross cable (pinout: 2 RxD/TxD, 3 TxD/RxD, 5 GND, 7 RTS/CTS, 8 CTS/RTS)

Notes

  • Command/response frames are hex byte sequences. Response frames start with command byte + 20h (e.g. command 02h → normal response 22h, error response A2h), then <ID1> <ID2> (control ID, model code), LEN, data, <CKS>.
  • Checksum: add all preceding bytes, take low-order one byte of the sum. Source example: 20h+81h+01h+60h+01h+00h=103h → CKS=03h.
  • No other command is accepted while power-on or power-off (including cooling) is in progress.
  • Picture/onscreen mute auto-cancel on input switch or signal switch; sound mute also cancels on volume adjustment.
  • Lamp/filter usage times have one-second resolution but update at one-minute intervals.
  • Some models cannot receive commands in standby mode (see Appendix "Standby Mode setting for receiving commands" — not in source).
  • Signal list numbers returned are actual value minus 1.
  • Lens continuous drive (7Fh plus / 81h minus) must be stopped by sending 00h; repeated identical commands keep the lens moving without stop.

Known Gaps

- "The manual defers per-model data to an Appendix (\"Connecting an External Device\", \"Supplementary Information by Command\") that is not included in the source text — input-terminal values, aspect values, eco-mode values, base-model types, sub-input values, and per-model command availability are unknown. Manual covers many projector models; V302H-specific support for LAN control not confirmable from source."
- "flow control not stated in source (RTS/CTS pins wired per pinout table)"
- "aspect values not in source"
- "target values not in source"
- "eco mode values not in source"
- "sub input values not in source"
- "input terminal values not in source"
- "no safety warnings, interlock procedures, or power-on sequencing requirements"
- "input terminal codes, aspect values, eco mode values, base model type values, PIP/PbP sub-input values, per-model command availability, standby command reception setting, flow control — all in manual Appendix not included in source."
- "firmware version compatibility not stated in source."
- "V302H-specific LAN control support not confirmable from source (manual is multi-model)."
- "source applicability inferred: the manufacturer protocol document names no model; commands verified against it but not confirmed for this exact model"
