Sharp/NEC PN-CD701 Control Spec

Summary

Sharp/NEC projector control spec covering RS-232C serial and wired/wireless LAN (TCP) control. Binary framed command protocol with hex opcodes, checksum bytes, and ID1/ID2 addressing. Source document is "Projector Control Command Reference Manual" (BDT140013 Revision 7.1). Device named per task input as PN-CD701.

Transport

# Source documents both RS-232C serial and LAN (TCP). Both emitted.
# Command/response framing: leading byte 20h/22h/etc = 20h + command-type;
# frame = <hdr> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1=control ID set on
# projector; ID2=model code (varies by model). CKS = low byte of sum of all
# preceding bytes. Short command lines in source omit header+ID1/ID2 (checksum
# already included as last byte); full frame adds 20h.. header and ID bytes.
protocols:
  - tcp
  - serial
addressing:
  port: 7142  # TCP port stated: "Use TCP port number 7142"
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source lists all five as supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow_control not stated (full-duplex comms mode stated)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many status/information request commands present
  - levelable    # inferred: VOLUME ADJUST, PICTURE ADJUST gain controls present
  - routable     # inferred: INPUT SW CHANGE input switching present

Variables

# UNRESOLVED: no discrete settable parameter registry beyond actions; gain/value

Events

# UNRESOLVED: source documents no unsolicited notifications; protocol is

Notes

• Framing: full command frame = <20h + cmdtype> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1 = control ID set on projector; ID2 = model code (varies by model). CKS = low-order byte of sum of all preceding bytes (example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
• The short command strings in the Actions section are copied verbatim from the source; they include the trailing checksum byte but omit the leading header byte and ID1/ID2, exactly as the source prints them.
• Error codes (ERR1/ERR2): 00h/00h=unrecognized; 00h/01h=not supported by model; 01h/00h=invalid value; 01h/01h=invalid input terminal; 02h/0Dh=power off; 02h/0Eh=execution failed; 02h/0Fh=no authority; 03h/00h-03h/02h=gain errors (full list in source §2.4).
• Lamp/filter usage returned in seconds, updated at 1-minute intervals. Lamp remaining life (%) can be negative if replacement deadline exceeded.
• Wireless LAN: see separate wireless LAN unit operation manual (not in this source).
• Appendix "Supplementary Information by Command" (input terminal codes, aspect values, eco mode values, sub input values, base model types) is referenced but NOT included in this refined source excerpt.

Known Gaps

- "source doc titled generically as \"Projector Control Command Reference Manual\"; PN-CD701 model name not confirmed verbatim inside source text. Firmware compatibility, voltage/power specs, and wireless LAN details not stated."
- "flow_control not stated (full-duplex comms mode stated)"
- "no discrete settable parameter registry beyond actions; gain/value"
- "source documents no unsolicited notifications; protocol is"
- "no multi-step sequences described in source."
- "model name \"PN-CD701\" supplied by operator; not found verbatim in source text (source is a generic projector command reference). Confirm against device label."
- "firmware version compatibility not stated."
- "flow_control not stated (full-duplex mode stated only)."
- "Appendix value tables (input terminals, aspect, eco mode, base model types) not present in source excerpt — param enums incomplete."
- "voltage / power / lamp wattage specs not in this source."
