AI4AVSummary
The NEC NP-PH1002HL Series is a professional projector controllable via RS-232C serial or wired LAN (TCP). The protocol uses binary (hexadecimal byte) framing with a checksum. This spec covers power control, input switching, picture/volume adjustment, lens control, mute functions, shutter, freeze, edge blending, PIP/PbP, and various status queries.

Variables
# No continuously-settable variables beyond the actions above.
# The gain parameter request/response pairs expose ranges and current values.
Events
# UNRESOLVED: no unsolicited notification mechanism described in source.
# All responses are solicited (command/response model).
Macros
# UNRESOLVED: no multi-step macro sequences described in source.
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety warnings or interlock procedures in the command reference.
# The error status response includes interlock switch status (DATA09 bit1) and cover error (DATA01 bit0).
# Power on/off commands block other commands during transitions but no confirmation is required by the protocol.
Notes
- All commands use binary (hexadecimal byte) framing with a checksum byte. Checksum is the low-order byte of the sum of all preceding bytes.
- Response success byte is the command byte with bit 5 set (e.g., 02h -> 22h, 03h -> 23h). Response failure byte has bit 5 set and bit 7 set (e.g., 02h -> A2h).
- Parameters
<ID1>(control ID) and<ID2>(model code) are present in all responses and vary per projector configuration. - Picture mute, sound mute, and onscreen mute are automatically cancelled on input switch or video signal switch. Sound mute is also cancelled on volume adjustment.
- Lens control (053) with continuous drive values (7Fh/81h) requires sending 00h to stop.
- Lens memory control (053-3) is separate from reference lens memory control (053-4), which operates on a selected profile.
- Lamp information reflects eco mode settings when eco mode is enabled.
- Usage time data is updated at 1-minute intervals despite being queryable in seconds.
- Some models cannot receive commands in standby mode via LAN.

Known Gaps
- "NP-PH1002HL Series is not listed in the supplementary tables for input terminal codes, aspect values, or eco mode values. The exact hex parameter values for those commands are model-specific and not documented for this model in the source."
- "not stated, but RTS/CTS pins present on connector"
- "NP-PH1002HL Series not listed in input terminal code table"
- "NP-PH1002HL Series not listed in aspect value table"
- "NP-PH1002HL Series not listed in eco mode value table"
- "no unsolicited notification mechanism described in source."
- "no multi-step macro sequences described in source."
- "no explicit safety warnings or interlock procedures in the command reference."
- "NP-PH1002HL Series is not listed in the supplementary tables for input terminal codes, aspect values, or eco mode values. The hex parameter values for input_switch, aspect_adjust, eco_mode_set, and audio_select_set are model-specific and must be determined from a NP-PH1002HL-specific source."
- "standby mode setting for receiving POWER ON command not documented for NP-PH1002HL Series."
- "the specific sub-input values for PIP/PbP commands reference an appendix not included in this source."
- "flow control method not stated despite RTS/CTS pins being present on the serial connector."
- "response timeout and command retry behavior not documented."
- "maximum command queue depth or rate limiting not documented."
