Sharp/NEC PN-LA652 Control Spec

Summary

Sharp/NEC large-format display/projector controlled via a binary RS-232C or TCP/IP command protocol (document BDT140013 Rev 7.1). Commands are hex frames consisting of a lead byte, command code, ID1 (control ID), ID2 (model code), data length, data bytes, and a checksum. This spec covers the full documented command catalogue: power, input switching, mute, picture/volume/aspect/gain adjust, shutter, lens control and memory, status/information queries, eco mode, PIP/PbP, edge blending, and audio select.

Transport

# Source documents both RS-232C (serial) and wired/wireless LAN (TCP).
# Commands are identical binary frames over either transport.
protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source lists selectable rates: 115200 / 38400 / 19200 / 9600 / 4800 bps (no single default stated)
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated; source states "Communication mode: Full duplex" only
auth:
  type: none  # inferred: no auth/login procedure in source

Traits

# - powerable   (POWER ON / POWER OFF commands present)
# - routable    (INPUT SW CHANGE - input terminal switching present)
# - queryable   (many status/information request commands present)
# - levelable   (picture adjust, volume adjust, gain adjust present)
traits:
  - powerable
  - routable
  - queryable
  - levelable

Actions

# Frame format (verbatim from source §2.1/§2.2):
#   <lead> <cmd1> [<cmd2>] <ID1> <ID2> <LEN> <DATA...> <CKS>
# - ID1 = control ID (00h = broadcast/default in examples)
# - ID2 = model code (00h in examples)
# - CKS (checksum) = low-order byte of the sum of ALL preceding bytes.
#     Example: 20h+81h+01h+60h+01h+00h = 103h -> CKS = 03h
# Commands below show the request payload verbatim. For parameterized
# commands, {dataNN} marks the variable byte(s) and {cks} is the computed
# checksum (low byte of sum of all preceding bytes including ID1=00h ID2=00h).
# Response leads: 20h/21h/22h/23h = success; A0h/A1h/A2h/A3h = error (carries ERR1 ERR2).
# See Notes for the full error-code table.

Safety

confirmation_required_for:
  - power_off  # turns off device; no other command accepted during power-off incl. cooling time
interlocks:
  - "POWER ON: while turning on, no other command can be accepted (source §3.2)."
  - "POWER OFF: while turning off (including cooling time), no other command can be accepted (source §3.3)."
  - "Interlock switch state is observable via error_status_request DATA09 bit1 (open = error) (source §3.1)."
  - "Forced onscreen mute on is reported as error code ERR1=02h ERR2=04h (source §2.4)."

Notes

• Binary protocol. Every request frame = <lead> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1=control ID, ID2=model code (both 00h/broadcast in all source examples). CKS = low byte of the sum of all preceding bytes.
• Responses: success leads 20h/21h/22h/23h (carry DATA + CKS); error leads A0h/A1h/A2h/A3h (carry ERR1, ERR2, CKS).
• Picture/volume/gain adjustments accept absolute (00h) or relative (01h/02h) modes with 16-bit signed values (low byte then high byte).
• Error-code table (ERR1 ERR2 -> description), verbatim from source §2.4:
  • 00h 00h = command not recognized
  • 00h 01h = command not supported by model
  • 01h 00h = specified value invalid
  • 01h 01h = specified input terminal invalid
  • 01h 02h = specified language invalid
  • 02h 00h = memory allocation error
  • 02h 02h = memory in use
  • 02h 03h = specified value cannot be set
  • 02h 04h = forced onscreen mute on
  • 02h 06h = viewer error
  • 02h 07h = no signal
  • 02h 08h = test pattern or filter displayed
  • 02h 09h = no PC card inserted
  • 02h 0Ah = memory operation error
  • 02h 0Ch = entry list displayed
  • 02h 0Dh = command cannot be accepted because power is off
  • 02h 0Eh = command execution failed
  • 02h 0Fh = no authority for the operation
  • 03h 00h = specified gain number incorrect
  • 03h 01h = specified gain invalid
  • 03h 02h = adjustment failed
• Several commands reference an appendix "Supplementary Information by Command" for full value lists (input terminal codes, aspect values, eco-mode values, base-model-type codes, sub-input codes). That appendix is not present in this source excerpt — affected parameter descriptions are marked accordingly.

Known Gaps

- "model name not explicitly printed in source; taken from the supplied device name. Firmware version, voltage/power specs, and protocol version not stated."
- "flow control not stated; source states \"Communication mode: Full duplex\" only"
- "min/max not fixed in source; queryable via gain_parameter_request_3 (DATA02-DATA05)"
- "queryable via gain_parameter_request_3"
- "source describes no unsolicited notifications. All responses are solicited replies to commands."
- "source documents no named multi-step command sequences."
- "no explicit power-on sequencing requirement stated beyond the command lockout"
- "firmware/protocol version not stated. Voltage, current, power specs not in source (out of scope for this command reference). Default baud rate not pinned (multiple selectable rates listed). Flow control not specified. Full input-terminal / aspect / eco-mode / base-model-type value tables require the appendix not included in the refined source."
