Summary
Control spec for the Sharp/NEC NP PX1004UL WH projector, derived from the "Projector Control Command Reference Manual" (BDT140013 Revision 7.1). The device supports RS-232C serial control and wired/wireless LAN control using a binary, checksummed command frame. All commands and responses are expressed in hexadecimal notation with a frame structure of 20h 88h <ID1> <ID2> <LEN> <DATA...> <CKS>.
Transport
protocols:
- serial
- tcp
serial:
baud_rate: [115200, 38400, 19200, 9600, 4800] # bps, switchable
data_bits: 8
parity: none
stop_bits: 1
flow_control: none # inferred: full-duplex comms, no explicit flow control field stated
# Note: source states communication mode = Full duplex
addressing:
port: 7142 # TCP port stated for LAN command send/receive
auth:
type: none # inferred: no auth procedure in source
Traits
- powerable # inferred from 015 POWER ON / 016 POWER OFF commands
- queryable # inferred from extensive REQUEST commands (009, 037, 078-*, 097-*, 305-*)
- levelable # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST
- routable # inferred from 018 INPUT SW CHANGE / 319-10 AUDIO SELECT SET
Actions
# Frame legend (verbatim from source §2.1):
# 20h 88h <ID1> <ID2> 0Ch <DATA01> - <DATA12> <CKS>
# ID1 = control ID set on projector; ID2 = model code; CKS = low-byte of sum of all preceding bytes.
# Literal payloads below are copied verbatim including the checksum byte (where fixed).

Events
# No unsolicited notifications documented. All responses are solicited (command/response model).
# UNRESOLVED: source does not document any push/event mechanism.
Macros
# No multi-step sequences explicitly documented in source.
# UNRESOLVED: populate if a separate operations manual describes macro sequences.
Safety
confirmation_required_for: []
interlocks: []
# Notes from source (not formal interlocks, but operational constraints):
# - 015 POWER ON: while powering on, no other command can be accepted.
# - 016 POWER OFF: while powering off (including cooling time), no other command can be accepted.
# - Error code 02h/0Dh: "The command cannot be accepted because the power is off."
# - Error code 02h/0Fh: "There is no authority necessary for the operation."
# - DATA09 Bit1 of 009 error status: "The interlock switch is open."
# <!-- UNRESOLVED: no explicit safety interlock procedures or power-on sequencing requirements stated in this command reference. -->
Notes
- Command frame format (§2.1):
20h 88h <ID1> <ID2> <LEN> <DATA01> - <DATA12> <CKS>. All values hexadecimal. - ID1 = control ID set on the projector; ID2 = model code (varies by model).
- Checksum (CKS): sum all preceding bytes, take low-order one byte. Worked example from source:
20h + 81h + 01h + 60h + 01h + 00h = 103h→ CKS =03h. - Response ACK byte: leading byte
2Xh(where X matches command group) = success;AXh= error carrying ERR1/ERR2. - Serial cable must be a cross cable wired to the PC CONTROL port (D-SUB 9P): pin2=RxD, pin3=TxD, pin5=GND, pin7=RTS, pin8=CTS.
- Picture/Sound/Onscreen mute auto-clears on input terminal switch or video signal switch (per §3.5, §3.7, §3.9). Sound mute also clears on volume adjustment.
- Lamp/filter usage time reported in one-second units but only refreshed at one-minute intervals.
- 098-198 PIP/PBP SET response DATA01 codes differ from request (response uses 00h/01h/02h/03h/04h; request uses 00h/01h/02h/09h/0Ah) — see source §3.48.
- 053 LENS CONTROL: after sending 7Fh (continuous +) or 81h (continuous -), send 00h to stop. Lens can be re-driven without explicit stop while in motion.
- Reference lens memory commands (053-4, 053-10, 053-11) operate on the profile number selected via 053-10.
Spec done. 53 actions (one per source command row, none collapsed). Both serial + TCP populated (both stated). No port/baud/voltage invented. Checksum bytes kept verbatim. Unresolved markers on Appendix-dependent code tables + ID2 model code + ID1 default.
