Summary
Sharp/NEC Pnm322 projector control spec covering RS-232C serial and TCP/IP (LAN) control. Binary hex command protocol with checksum byte; supports power, input switching, mute, picture/volume/lens adjust, lens memory, status queries, and edge blending.

Events
# UNRESOLVED: no unsolicited notifications documented in source. Device is poll-only.
Macros
# UNRESOLVED: no explicit multi-step sequences described in source.
Safety
confirmation_required_for:
- power_off # source notes cooling time during which no commands accepted
interlocks:
- "POWER ON: no other command accepted while power-on in progress"
- "POWER OFF: no other command accepted during power-off including cooling time"
- "Error DATA09 Bit1: interlock switch open is a defined error condition"
# UNRESOLVED: source contains no explicit power-on sequencing requirements or external interlock procedures beyond the error bitmask definition.
Notes
- Command/response framing: hex byte strings. Frame uses leading command-class byte (00h–03h for requests, 20h–23h for success responses, A0h–A3h for error responses).
- Parameters ID1 (control ID), ID2 (model code), CKS (checksum) are common to all commands.
- Checksum = low-order 8 bits of sum of all preceding bytes.
- Error responses carry ERR1+ERR2 pair — see source error code list (00h/00h unrecognized, 02h/0Dh power off, etc.).
- Signal list number returned is 1 less than practical value (add 1).
- Lamp/filter usage info updates at 1-minute intervals despite 1-second resolution.
- Appendices referenced ("Supplementary Information by Command") are not in this source extract — values for input terminal, eco mode, base model type, and sub input are UNRESOLVED.
Spec above. 53 actions enumerated — every command row in source 2. Command List covered. Hex payloads verbatim. Ports/serial config direct from source. UNRESOLVED markers on gaps (baud default, appendix values, firmware).
