NEC NP P547UL P627UL Control Spec

Summary

Laser projectors supporting both RS-232C serial and wired LAN (TCP/IP) control. Commands sent via hex-encoded packets with ID1/ID2 control IDs, checksum validation, and structured response frames. TCP port 7142. No authentication procedure described.

Variables

# UNRESOLVED: variables are settable parameters; source describes query+set pairs for eco mode, projector name, PIP/PbP, edge blending, lens memory option - all modeled as actions above with corresponding requests in Feedbacks

Events

# UNRESOLVED: source describes no unsolicited event notifications from the device. All communication is command-response.

Macros

# UNRESOLVED: no explicit multi-step macros described in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no safety warnings or interlock procedures stated in source

Notes

Command packet structure: [PREAMBLE] [MODEL] <ID1> <ID2> [LEN] [DATA...] [CKS] — preamble and model bytes vary by command class (00h/01h/02h/03h for queries, 20h/22h/23h for responses). Checksum = low-order byte of sum of all preceding bytes. Power on/off commands block other commands during execution (including cooling time for power off). Lens drive commands (7Fh/81h) can be stopped by sending 00h. Lamp usage time updates at 1-minute intervals despite 1-second resolution. Power state enum from RUNNING STATUS: 00h=Standby(Sleep), 01h=Power on, 05h=Cooling, 06h=Standby(error), 0Fh=Standby(Power saving), 10h=Network standby.
