Summary

Sharp/NEC projector (LED E012I 217In) controlled via an RS-232C serial port (PC CONTROL, D-SUB 9P) or a wired/wireless LAN (TCP port 7142). This spec covers the binary hex command catalogue documented in the "Projector Control Command Reference Manual" (BDT140013 Rev 7.1), including power, input switching, mutes, picture/volume/aspect/lamp adjust, lens control and memory, shutter, freeze, eco mode, edge blending, PIP/PbP, and status/error/lamp/filter/info requests.

Notes

  • Reference manual identifier: BDT140013 Rev 7.1. Generic multi-model Sharp/NEC projector manual; not specific to LED E012I 217In. Some commands/values vary by model — see "Appendix: Supplementary Information by Command" referenced throughout but not included in the refined source excerpt.
  • Frame format: op1 op2 00h 00h LEN DATA?? CKS. Response frames prefix op1 with 20h/21h/22h/23h (success) or A0h/A1h/A2h/A3h (failure, followed by <ERR1> <ERR2> <CKS>).
  • Checksum = low-order byte of the sum of all preceding bytes (incl. header and LEN). Source example: 20h 81h 01h 60h 01h 00h → sum 103h → CKS 03h.
  • Error code pairs (ERR1/ERR2) are documented in source §2.4 (e.g. 00h/00h unrecognized, 00h/01h not supported by model, 01h/00h invalid value, 02h/0Dh power off, 02h/0Eh execution failed, 02h/0Fh no authority).
  • ID1 (control ID) and ID2 (model code) byte values for this specific projector are not stated in this generic manual — must be read from the device configuration.
  • Several "see Appendix Supplementary Information by Command" cross-references appear (input terminal values, aspect values, eco mode values, sub input values, base model types). That appendix was not present in the refined source excerpt; enum values for those parameters are UNRESOLVED.

Spec done. 55 commands enumerated, all hex payloads verbatim. Serial + TCP (port 7142). Baud rate list 5 values from source. Auth inferred none. 2 interlocks + power-off rejection documented. Appendix-referenced enums (input terminal, aspect, eco mode, sub input, base model type) marked UNRESOLVED — refined source lack appendix. ID1/ID2 byte values for this model UNRESOLVED (generic manual).
