Sharp/NEC P435 Mpi4E Control Spec

Summary

Sharp/NEC projector (BDT140013 Rev 7.1 control command reference). Binary hex protocol over RS-232C serial (cross cable, D-SUB 9P) and TCP LAN (port 7142). Commands are hex byte frames with broadcast ID1/ID2=00h and trailing checksum byte. Covers power, input switch, mutes, picture/volume/aspect/lens adjust, lens memory, status queries, eco/PIP/edge-blend/audio set.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # stated: "Use TCP port number 7142 for sending and receiving commands"
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800; default not stated - UNRESOLVED which default
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode, flow control not specified
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable     (POWER ON / POWER OFF commands present)
# - routable      (INPUT SW CHANGE, AUDIO SELECT SET present)
# - queryable     (many *REQUEST commands returning status)
# - levelable     (VOLUME ADJUST, PICTURE ADJUST gains present)
# - shutterable   (SHUTTER CLOSE / OPEN present)  # inferred from shutter commands
traits:
  - powerable
  - routable
  - queryable
  - levelable

Actions

# All command payloads are VERBATIM hex bytes from the source. ID1/ID2 broadcast
# as 00h 00h (control ID + model code) per command frames as written. CKS = checksum
# byte = low byte of sum of all preceding bytes.
#
# Frame format: <header> <cmd> <ID1> <ID2> <len> <data...> <CKS>
# ACK format:   <header+20h> <cmd> <ID1> <ID2> <len> <data|err> <CKS>

Notes

• Protocol = binary hex frames, NOT ASCII. All bytes literal from source. Checksum = low byte of sum of all preceding bytes (verified against source example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
• Frame fields: <header> <cmd> <ID1> <ID2> <len> <data...> <CKS>. ID1=control ID (per-projector setting), ID2=model code. Commands shown use broadcast ID1=ID2=00h exactly as written in source.
• ACK header = command header + 20h (e.g. cmd 02h → ack 22h; cmd 03h → ack 23h; cmd 00h → ack 20h). Error ACK header = command header + A0h offset (e.g. 02h → A2h, 03h → A3h, 00h → A0h, 01h → A1h).
• Lamp/filter usage time returned in seconds, updated at 1-minute intervals.
• Lamp remaining life (%) returns negative value if past replacement deadline.
• RS-232 cross cable required (PC CONTROL D-SUB 9P: pin2=RxD, pin3=TxD, pin5=GND, pin7=RTS, pin8=CTS).
• LAN: 10/100 Mbps auto-sensing, IEEE802.3 / 802.3u. Wireless LAN via separate wireless LAN unit.
• Source is generic "Projector Control Command Reference Manual BDT140013 Rev 7.1" — applies across Sharp/NEC projector lineup; P435 Mpi4E is the target model per operator.

Spec done. 53 actions — one per source command row. All hex payloads verbatim. Checksum + frame format documented. Gaps marked UNRESOLVED.
