Summary

Sharp/NEC VT800 projector control spec covering RS-232C serial and wired/wireless LAN (TCP) control interfaces, per the "Projector Control Command Reference Manual" (document BDT140013, revision 7.1). The protocol is a binary, hex-byte command set with a trailing checksum byte, framed as <header> <ID1> <ID2> <LEN> <DATA...> <CKS>.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # stated: "Use TCP port number 7142 for sending and receiving commands."
serial:
  baud_rate: 115200  # UNRESOLVED: source lists supported rates 115200/38400/19200/9600/4800 bps but does not state a default; 115200 shown as a placeholder.
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but does not specify flow_control (RTS/CTS wiring is present on the D-SUB 9P connector).
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many *REQUEST commands return state values
  - levelable    # inferred: PICTURE/VOLUME/LAMP ADJUST commands present
  - routable     # inferred: INPUT SW CHANGE / AUDIO SELECT SET present

Actions

# All 53 commands from Section 2 "Command List" enumerated verbatim.
# Hex payloads copied verbatim from source (h suffix preserved). Computed
# fields (ID1, ID2, CKS) shown as <ID1> <ID2> <CKS> placeholders per source.
# Each source row = one action (no collapsing of enumerated variants).

# Ack/error response framing: every command returns either a success response

# the command header) carrying <ERR1> <ERR2> <CKS>. Example for POWER ON:
#   success: "22h 00h <ID1> <ID2> 00h <CKS>"
#   error:   "A2h 00h <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>"

# UNRESOLVED: structured variable entries not authored; source encodes values
# inside binary DATA fields rather than as discrete named parameters. Mapping
# byte offsets to a variable schema would exceed direct population policy.

Events

# No unsolicited notifications are described in the source. All responses are
# direct replies to commands.
# UNRESOLVED: not applicable - no event documentation found.

Macros

# No multi-step sequences are described explicitly in the source.
# UNRESOLVED: not applicable.

Notes

  • Protocol framing. Commands are binary hex-byte frames. Layout per section 2.1: <Header> <ID1> <ID2> <LEN> <DATA01>..<DATA?? <CKS>. ID1 is the projector's configured control ID; ID2 is the model code (varies by model); LEN is the byte count of the DATA portion; CKS is a checksum computed as the low-order byte of the sum of all preceding bytes (section 2.2). Checksum example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Response headers. A success response header is the command header byte +20h; an error response header is the command header byte +80h. Examples verbatim from the source are reproduced in each command's payload line.
  • Appendix dependency. Several commands reference an "Appendix: Supplementary Information by Command" for value tables (input terminals, aspect values, eco-mode values, sub-input values, base model types). That appendix is NOT included in this refined source excerpt, so those value enumerations are marked as deferred in params[].description.
  • Multi-rate serial. RS-232C supports 4800/9600/19200/38400/115200 bps; the source does not name a default, so implementers must match the projector's configured rate.
  • Cooling lockout. During the post-power-off cool-down the device will not accept any command (documented in 3.3 and reflected by ERR 02h 0Dh "power is off").

## Known Gaps

```yaml
- "source is a generic projector control manual (BDT140013 R7.1), not a VT800-specific document. The VT800 model name is supplied by the operator; the source itself does not name a model. Confirm VT800 actually uses this command set."
- "source lists supported rates 115200/38400/19200/9600/4800 bps but does not state a default; 115200 shown as a placeholder."
- "source states \"Full duplex\" communication mode but does not specify flow_control (RTS/CTS wiring is present on the D-SUB 9P connector)."
- "structured variable entries not authored; source encodes values"
- "not applicable - no event documentation found."
- "not applicable."
- "source does not document formal interlock procedures, power-on"
- "(1) VT800 model attribution is operator-supplied; the source document does not name a model. (2) Default baud rate not stated. (3) Flow-control mode not stated (RTS/CTS pins are wired on the D-SUB 9P connector but the source says only \"Full duplex\"). (4) Firmware version compatibility not stated. (5) Appendix value tables (input terminal codes, aspect codes, eco-mode codes, sub-input codes, base-model-type codes) are referenced but not present in this excerpt. (6) ID2 model code for the VT800 is not stated."
