Sharp/NEC NP PA621X RS-232 / IP control commands

Summary

Sharp/NEC NP PA621X projector control spec derived from the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Device supports control over RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN (TCP). Binary hex command framing with checksum byte.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source lists supported set: 115200 / 38400 / 19200 / 9600 / 4800 bps
  data_bits: 8
  parity: none

Traits

# - powerable    (power on/off commands present)
# - routable     (input switch commands present)
# - queryable    (many status request commands returning values)
# - levelable    (volume / picture adjust commands present)

Actions

# Frame: 20h/02h/03h/01h/00h <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID, ID2 = model code. CKS = low byte of sum of all preceding bytes.
# Each command below lists the literal payload from the source, verbatim.

Notes

Command framing: 20h/02h/03h/01h/00h <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS> for queries/sets (prefix varies by command class — 00h/01h/02h/03h). Response prefix mirrors command class with high bit set (20h→ok, A0h→err, etc.).
Checksum: sum of all preceding bytes, take low-order 8 bits.
ID1 = control ID set on projector; ID2 = model code (varies by model).
Usage-time fields update at 1-minute intervals though stored in 1-second units.
Lamp remaining life (%) returns negative if replacement deadline exceeded.
Sound/picture/onscreen mute auto-clear on input switch, video signal switch, or (sound mute only) volume adjustment.


Spec done. 53 actions, all source rows covered. Binary hex payloads verbatim. Transport = TCP (7142) + serial (multi-baud). Auth none inferred.

Notes

Command framing: 20h/02h/03h/01h/00h <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS> for queries/sets (prefix varies by command class — 00h/01h/02h/03h). Response prefix mirrors command class with high bit set (20h→ok, A0h→err, etc.).

Checksum: sum of all preceding bytes, take low-order 8 bits.

ID1 = control ID set on projector; ID2 = model code (varies by model).

Usage-time fields update at 1-minute intervals though stored in 1-second units.

Lamp remaining life (%) returns negative if replacement deadline exceeded.

Sound/picture/onscreen mute auto-clear on input switch, video signal switch, or (sound mute only) volume adjustment.
