Sharp/NEC E328 Control Spec

Summary

Sharp/NEC E328 projector controlled via RS-232C (PC CONTROL D-SUB 9P) or wired/wireless LAN. Binary command protocol with hex framing, checksum byte, and fixed response frames. Manual BDT140013 Rev 7.1 documents 53 commands spanning power, input switching, mutes, picture/volume/aspect/lamp adjustment, lens & lens memory control, eco/PIP/edge-blend set, and many status queries.

Transport

protocols:

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF
  - routable     # inferred: 018 INPUT SW CHANGE
  - queryable    # inferred: extensive *REQUEST command set
  - levelable    # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 030-15 OTHER ADJUST

Actions

# Framing: commands shown are the literal payload from projector's perspective
# (byte 0 = command class, includes checksum CKS). Responses prefixed 2xh/Axh
# echo <ID1>=control ID and <ID2>=model code. CKS = low byte of sum of all
# preceding bytes. Parameterized DATA bytes shown as <DATAxx>.

Notes

• Manual revision: BDT140013 Rev 7.1. All commands expressed in hex.
• Checksum (CKS) = low-order byte of sum of all preceding bytes. Worked example in source: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
• Framing: commands start with class byte (00h=read-only query, 01h/02h/03h=write/action). Successful response prefixes: 20h/21h/22h/23h (echo DATA). Error response prefix: A0h/A1h/A2h/A3h (high bit set), carrying <ERR1> <ERR2>.
• Error codes (ERR1/ERR2): 00h/00h=unrecognized, 00h/01h=unsupported by model, 01h/00h=invalid value, 01h/01h=invalid input terminal, 02h/0Dh=power off, 02h/0Eh=exec failed, 02h/0Fh=no authority, 03h/00h-02h=gain errors. See source §2.4 for full 30-entry table.
• ID2 (model code) varies by model — not stated for E328 in this manual.
• Appendix "Supplementary Information by Command" (referenced for input terminal values, aspect values, eco mode values, base model types, sub input values) is not present in this refined source — those enums are UNRESOLVED.

Spec done. 53 actions enumerate every command row from §3. All literal hex payloads verbatim with CKS. UNRESOLVED markers on 6 appendix-dependent value tables + model code + firmware.
