Sharp/NEC ME501 PT Control Spec

Summary

Sharp/NEC ME501 PT projector control spec. Binary hex protocol over RS-232C serial and TCP/IP (port 7142). Covers power, input switch, mutes, lens/shutter, picture/volume/aspect adjust, eco mode, PIP/PbP, edge blending, and many status queries. Source: "Projector Control Command Reference Manual" BDT140013 Rev 7.1 — generic manual, may cover multiple Sharp/NEC models beyond ME501 PT.

Variables

# Discrete settable params (not covered as actions) - none beyond those already
# represented as parameterized Actions above. Picture/volume/aspect/lens-adjust
# ranges returned dynamically by 060-1 GAIN PARAMETER REQUEST 3.

Events

# Source documents no unsolicited notifications. All responses are replies to commands.

Macros

# Source documents no named multi-step macros.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements. Note: 015 POWER ON / 016 POWER OFF reject
# other commands during transition (incl. cooling time), and 009 ERROR STATUS
# REQUEST bit DATA09 Bit1 'interlock switch is open' is reported - but no
# operator interlock procedure is documented.

Notes

• All commands are binary hex frames. Format: {lead} {cmd} {ID1} {ID2} {LEN} {DATA...} {CKS}. Lead bytes: 00h=request group, 01h=freeze group, 02h=control group, 03h=set/adjust group. Response leads: 20h/21h/22h/23h (success), A0h/A1h/A2h/A3h (error).
• Checksum (CKS) = low-order byte of sum of all preceding bytes. Example: 20h 81h 01h 60h 01h 00h → 103h → CKS=03h.
• ID1 = control ID set on projector. ID2 = model code (varies by model). ERR1/ERR2 returned on failure (see source §2.4 error code list — 30 distinct error codes documented).
• Power On (015) and Power Off (016) reject all other commands during the transition. Picture/Sound/Onscreen mute auto-clear on input switch or signal switch.
• Source is generic "Projector Control Command Reference Manual" BDT140013 Rev 7.1. May cover multiple Sharp/NEC projector models; per-model command subset not stated.

Spec done. 53 source commands → 24 actions + 24 feedbacks (queries). All hex payloads verbatim. UNRESOLVED markers on appendix-referenced value tables, flow control, default baud, ID2 model code, firmware.
