Sharp-NEC P547UL Series Control Spec

Summary

The Sharp-NEC P547UL Series is a laser projector controllable via RS-232C serial or TCP/IP (wired LAN, port 7142). This spec covers the binary command protocol for power control, input switching, picture/sound/onscreen mute, lens control (zoom, focus, shift), lens memory, shutter, freeze, picture/volume/aspect adjustment, eco mode, edge blending, PIP/PbyP, and various status queries. Commands are fixed-length hex byte sequences with a trailing checksum.

Events

# UNRESOLVED: no unsolicited notification mechanism described in source

Macros

# No multi-step sequences explicitly described in source beyond sequential lens memory operations.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source mentions interlock switch in error status (DATA09 Bit1) but no explicit
# safety interlock procedure or power-on sequencing requirement is documented.
# Power on/off commands block other commands during execution.

Notes

• Binary protocol: all commands and responses are hex byte sequences. Checksum is low-order byte of sum of all preceding bytes.
• Command frame structure: <CMD_BYTE> <SUB_BYTE> <ID1> <ID2> <LEN> <DATA...> <CKS>
• ID1 = control ID set on projector, ID2 = model code (varies by model).
• Response prefix distinguishes success (bit 7 cleared with 20h/21h/22h/23h) from failure (A0h/A1h/A2h/A3h).
• Error responses include ERR1 and ERR2 bytes indicating the cause of failure.
• Serial connector: D-SUB 9P with RTS/CTS handshaking lines.
• LAN connector: RJ-45, auto-negotiating 10/100 Mbps.
• Lamp usage time and filter usage time are updated at 1-minute intervals despite being returned in seconds.
• The supplementary tables in the source only cover NP-M, NP-ME, and NP4100 series models — P547UL-specific values for input terminal codes, aspect codes, and eco mode codes are not documented.
