Sharp/NEC NP-PV800UL-W1-41ZL control commands

Summary

Sharp/NEC NP-PV800UL-W1-41ZL professional LCD projector. This spec covers the binary control protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), carried over both RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN using TCP port 7142. The protocol is a framed binary format with per-message checksum and control-ID/model-code echo in responses.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists selectable rates: 115200 / 38400 / 19200 / 9600 / 4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source: full-duplex communication; explicit RTS/CTS pins present but no hardware flow-control mode stated
addressing:
  port: 7142  # TCP port for LAN command send/receive, stated verbatim in source
auth:
  type: none  # inferred: no auth/login procedure described in source
# Framing: every request is a hex byte sequence <HDR> <CMD> 00h 00h <LEN> <DATA...> <CKS>,
# where <CKS> is the low byte of the sum of all preceding bytes. Responses are
# <HDR_ACK> <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS> on success, or
# <HDR_ERR> <CMD> <ID1> <ID2> 02h <ERR1> <ERR2> <CKS> on failure.
# ID1 = projector control ID; ID2 = model code (echoed by projector).
# HDR per request class: 00h=info-query, 01h=freeze, 02h=command, 03h=adjust/query-3.
# ACK header = HDR + 20h; ERR header = HDR + A0h.

Traits

traits:
  - powerable      # inferred: POWER ON (015) / POWER OFF (016) commands present
  - routable       # inferred: INPUT SW CHANGE (018) and audio select / PIP sub-input routing present
  - queryable      # inferred: numerous status/information request commands return state
  - levelable      # inferred: VOLUME ADJUST, PICTURE ADJUST, LAMP/LIGHT ADJUST present
  - mutable        # inferred: PICTURE/SOUND/ONSCREEN MUTE on/off present

Actions

# All payloads are verbatim hex byte sequences from the source.
# Fixed commands embed their computed checksum as the trailing byte.
# Parameterized commands show the variable DATA bytes and require a
# recomputed checksum (sum of all preceding bytes, low-order byte).
# See "Transport" framing note for ID1/ID2/CKS rules.

Notes

Protocol is binary, frame-based, big-endian hex bytes. All command bytes are documented in hexadecimal (e.g. 02h).
Request frames do NOT carry ID1/ID2; they carry a trailing checksum (low byte of sum of all preceding bytes). Responses echo ID1 (control ID) and ID2 (model code).
ACK header = request-header + 20h (e.g. 02h→22h, 03h→23h, 00h→20h, 01h→21h). Error header = request-header + A0h (e.g. 02h→A2h).
Error responses carry ERR1/ERR2 per the source error-code table (00h/00h unrecognized command, 02h/0Dh command rejected because power off, 02h/0Fh no authority, 03h/02h adjustment failed, etc.).
Serial cable must be a cross cable wired to the PC CONTROL D-SUB 9P (RxD/TxD crossed, RTS/CTS crossed, GND common).
LAN: wired RJ-45 (10/100BASE-TX auto-negotiation) and optional wireless LAN unit; both use TCP port 7142.
Lamp/filter usage times are reported in one-second units but are updated only at one-minute intervals.
Lamp remaining life (%) returns a negative value once the replacement deadline is exceeded.

# Framing: every request is a hex byte sequence <HDR> <CMD> 00h 00h <LEN> <DATA...> <CKS>,

# HDR per request class: 00h=info-query, 01h=freeze, 02h=command, 03h=adjust/query-3.

Traits

traits:
  - powerable      # inferred: POWER ON (015) / POWER OFF (016) commands present
  - routable       # inferred: INPUT SW CHANGE (018) and audio select / PIP sub-input routing present

Actions

# All payloads are verbatim hex byte sequences from the source.
# Fixed commands embed their computed checksum as the trailing byte.
# Parameterized commands show the variable DATA bytes and require a
# recomputed checksum (sum of all preceding bytes, low-order byte).

Notes

Protocol is binary, frame-based, big-endian hex bytes. All command bytes are documented in hexadecimal (e.g. 02h).
Request frames do NOT carry ID1/ID2; they carry a trailing checksum (low byte of sum of all preceding bytes). Responses echo ID1 (control ID) and ID2 (model code).
ACK header = request-header + 20h (e.g. 02h→22h, 03h→23h, 00h→20h, 01h→21h). Error header = request-header + A0h (e.g. 02h→A2h).
Error responses carry ERR1/ERR2 per the source error-code table (00h/00h unrecognized command, 02h/0Dh command rejected because power off, 02h/0Fh no authority, 03h/02h adjustment failed, etc.).
Serial cable must be a cross cable wired to the PC CONTROL D-SUB 9P (RxD/TxD crossed, RTS/CTS crossed, GND common).
LAN: wired RJ-45 (10/100BASE-TX auto-negotiation) and optional wireless LAN unit; both use TCP port 7142.
Lamp/filter usage times are reported in one-second units but are updated only at one-minute intervals.
Lamp remaining life (%) returns a negative value once the replacement deadline is exceeded.
