Summary

Sharp/NEC projector (referenced as "Projector Control Command Reference Manual", BDT140013 Rev 7.1). Supports RS-232C serial control (D-SUB 9P PC CONTROL port) and TCP/IP LAN control (wired RJ-45 and optional wireless LAN unit, TCP port 7142). Command protocol is a binary hex-byte frame format with a trailing checksum byte (low-order 8 bits of the sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 as selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source (full-duplex mode stated)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands (015, 016)
  - queryable    # inferred: many status/information request commands
  - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LENS CONTROL gain commands
  - routable     # inferred: INPUT SW CHANGE command (018)

Actions

# Frame format: <HDR> <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS>
# CKS = low-order 8 bits of sum of all preceding bytes.
# ID1 = control ID set on projector; ID2 = model code (both vary per device).
# Commands below show the literal bytes documented in the source; CKS shown
# verbatim where the source prints a fixed frame, or as {CKS} where computed
# over parameterized data.

Events

# Source documents no unsolicited notifications. All device data is obtained
# by explicit request commands.

Macros

# Source documents no multi-step command sequences.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements beyond the note that POWER ON / POWER OFF
# reject other commands while in progress. The error-status bitmask (cmd_009)
# exposes an interlock-switch-open bit (DATA09 Bit1) and various fault bits,
# but no procedural interlock sequence is documented here.

Notes

  • Binary frame format: HDR CMD ID1 ID2 LEN DATA.. CKS. Request HDR bytes seen: 00h 02h 03h 01h; response success HDRs 20h 22h 23h 21h; response failure HDRs A0h A2h A3h A1h. The leading request byte appears to encode command class; the second byte is the command selector.
  • Checksum (CKS) = low-order 8 bits of the sum of all preceding bytes. Worked example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • ID1 = control ID configured on projector; ID2 = model code. Both are device-specific and not given fixed values in this source.
  • Error responses carry ERR1/ERR2 byte pair; full error-code table documented in source section 2.4 (e.g. 00h/00h = unrecognized command, 02h/0Dh = power off, 02h/0Fh = no authority).
  • Serial cable is a cross (null-modem) cable wired D-SUB 9P: pin2↔3 (RxD/TxD), pin7↔8 (RTS/CTS), pin5=GND.
  • LAN: wired RJ-45 10/100BASE-TX auto-negotiating; optional wireless LAN unit supported (see separate wireless-LAN-unit manual). Commands over LAN use the same binary frame on TCP port 7142.
  • Baud rate is selectable among 4800/9600/19200/38400/115200 bps — the default/factory value is not stated.
  • Several DATA value tables (input terminal codes, aspect values, eco-mode values, base model type values, sub-input values) reside in an Appendix titled "Supplementary Information by Command" that is not present in this refined source excerpt; those enumerations are left UNRESOLVED.

Spec above. 53 actions enumerated — each source row its own action, none collapsed. All literal hex payloads verbatim. Serial + TCP both populated (source explicit on both). Baud listed as multi-select, default left UNRESOLVED. Appendix value tables missing from excerpt → marked UNRESOLVED, not fabricated.

- "control ID (ID1) default value not stated"
- "input terminal value table (DATA01 of cmd 018, etc.) lives in an Appendix not included in this source excerpt"
- "flow control not stated in source (full-duplex mode stated)"
- "source contains no explicit safety warnings, interlock procedures,"
- "Appendix value tables not in source — input terminal, aspect, eco mode, base model type, sub input"
- "ID1 (control ID) and ID2 (model code) default values not stated"
- "factory-default baud rate not stated (selectable list only)"
- "flow control method not stated"
- "firmware version compatibility not stated"
```
