Summary

Sharp/NEC NP MC372X projector control spec covering RS-232C serial and wired/wireless LAN (TCP) control per the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands use a binary hex frame with a leading byte, command bytes, parameters, and a trailing checksum byte (low-order 8 bits of the sum of all preceding bytes). Covers power, input switching, mute, lens/shutter, picture/volume/aspect adjustment, lamp/filter/info queries, lens memory, eco mode, PIP/PbP, edge blending, and audio select.

Transport

protocols:
  - serial
  - tcp
# Connector: PC CONTROL port D-SUB 9P (cross cable). LAN: RJ-45 (wired) / wireless LAN unit.
serial:
  baud_rate: null  # UNRESOLVED: source lists selectable rates 115200/38400/19200/9600/4800 bps; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: not stated in source (RTS/CTS pins present on connector but flow_control setting unspecified)
  communication_mode: full_duplex
addressing:
  port: 7142  # TCP port for command send/receive over LAN
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON (015) / POWER OFF (016) commands present
  - queryable       # inferred: many status/information request commands present
  - levelable       # inferred: volume, brightness, contrast, color, hue, sharpness, lamp adjust present
  - routable        # inferred: INPUT SW CHANGE (018) input terminal switching present

Actions

# Frame format: <lead> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>
# CKS = low-order 8 bits of the sum of all preceding bytes (computed).
# ID1 = projector control ID; ID2 = model code. Both vary per device.
# Response lead bytes: 2xh = success (2-digit cmd echo), Axh = error with ERR1/ERR2.
#
# Hex values shown verbatim from source; parameters in <DATA??> placeholders.

Events

# UNRESOLVED: source documents no unsolicited notifications. All responses are command-acknowledgement frames (success 2xh / error Axh).

Macros

# UNRESOLVED: source documents no multi-step command sequences.

Safety

confirmation_required_for: []
interlocks: []
# Notes from source (informational, not safety interlock procedures):
#   - POWER ON (015): no other command accepted during power-on sequence.
#   - POWER OFF (016): no other command accepted during power-off incl. cooling time.
#   - Lens drive (053): continuous drive via 7Fh/81h must be stopped by sending 00h.
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures, or
# power-on sequencing requirements. Cover/interlock-switch status is queryable (009, 078-6)
# but no safety procedure is documented.

Notes

  • Frame structure: <lead> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. Lead byte encodes direction (0xh/1xh/2xh/3xh = command variants; 2xh = success response; Axh = error response). ID1 = projector control ID; ID2 = model code (device-specific).
  • Checksum (CKS): low-order 8 bits of the sum of all preceding bytes. Source example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Responses: success returns 2xh frame (no data part if command doesn't request data, with data if it does); failure returns Axh frame with ERR1/ERR2.
  • Error codes (ERR1/ERR2): 00h/00h=unrecognized command, 00h/01h=not supported by model, 01h/00h=invalid value, 01h/01h=invalid input terminal, 01h/02h=invalid language, 02h/00h=memory allocation error, 02h/02h=memory in use, 02h/03h=value cannot be set, 02h/04h=forced onscreen mute on, 02h/06h=viewer error, 02h/07h=no signal, 02h/08h=test pattern/filter displayed, 02h/09h=no PC card inserted, 02h/0Ah=memory operation error, 02h/0Ch=entry list displayed, 02h/0Dh=command rejected (power off), 02h/0Eh=execution failed, 02h/0Fh=no authority, 03h/00h=incorrect gain number, 03h/01h=invalid gain, 03h/02h=adjustment failed.
  • Signal list number: returned value is practical number minus 1; add 1 to get the practical number.
  • Usage time granularity: lamp/filter usage time available in 1-second units but updated at 1-minute intervals.
  • Lamp 2: 01h (Lamp 2) in 037-4 DATA01 effective only on two-lamp models.

Known Gaps

- "model name \"NP MC372X\" supplied by operator; the source manual is generic and does not name a specific model. Firmware version, voltage/power specs, and exact default serial rate not stated in source."
- "source lists selectable rates 115200/38400/19200/9600/4800 bps; default not stated"
- "not stated in source (RTS/CTS pins present on connector but flow_control setting unspecified)"
- "get path not documented in source excerpt"
- "source documents no unsolicited notifications. All responses are command-acknowledgement frames (success 2xh / error Axh)."
- "source documents no multi-step command sequences."
- "source contains no explicit safety warnings, interlock procedures, or"
- "input terminal value list (018, 319-10), aspect value list (030-12), eco mode value list (097-8/098-8), sub input value list (097-198/098-198), base model type value list (078-1/305-1) are referenced as \"see Appendix 'Supplementary Information by Command'\" but the Appendix is not included in the source excerpt."
- "default serial baud rate not stated (5 selectable rates given)."
- "serial flow_control not stated (RTS/CTS pins wired but setting unspecified)."
