Summary

Sharp/NEC NP-PH3501QL is a projector controllable via an RS-232C serial interface and a wired/wireless LAN using TCP port 7142. This spec covers the binary command protocol described in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mute, picture/volume/aspect adjustment, lens and lens-memory control, and a broad set of status information requests.

Events

# UNRESOLVED: no unsolicited notification documented in source. All responses are replies to commands.

Macros

# UNRESOLVED: no multi-step sequences explicitly described in source.

Safety

confirmation_required_for: []
interlocks:
  - command: "015. POWER ON"
    note: "While turning on power, no other command can be accepted."
  - command: "016. POWER OFF"
    note: "While turning off power (including cooling time), no other command can be accepted."
  - command: "053. LENS CONTROL"
    note: "Continuous drive (DATA02=7Fh/+ or 81h/-) must be stopped by sending DATA02=00h."
# Source documents error code 02h 0Dh "command cannot be accepted because the power is off" -
# many commands require power-on. No external-interlock procedure beyond the bitfield
# "interlock switch is open" reported in 009 ERROR STATUS REQUEST DATA09 bit1.

Notes

  • All commands are binary; responses are framed as A<major>h <minor>h <ID1> <ID2> <LEN> <DATA...> <CKS>. Successful responses use major byte 2Xh (mirroring the command's major byte); error responses use AXh with <ERR1> <ERR2>.
  • Checksum (CKS) = low-order byte of the sum of all preceding bytes.
  • ID1 = projector control ID; ID2 = model code (varies by model).
  • Lamp usage time and filter usage time are returned in seconds and updated at one-minute intervals.
  • Lamp remaining life (%) may be negative if the replacement deadline is exceeded.
  • Error codes are a two-byte combination of ERR1/ERR2 (see §2.4).
  • Commands 02h-prefixed (POWER/MUTE/SHUTTER/LENS CONTROL etc.) use response major 22h; 03h-prefixed use 23h; 00h-prefixed use 20h; 01h-prefixed (FREEZE) uses 21h.
  • RS-232C uses a D-SUB 9P cross cable; RTS/CTS pins are wired but no named flow-control mode is documented.
  • Pin 1 of the LAN port function labels (TD±/RD±) are stated; PHY is auto-sensing 10/100.
