Summary

Control spec for the Sharp/NEC 8M B120C projector, covering the binary command protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). The device accepts control over RS-232C serial and TCP/IP LAN (port 7142). Commands are framed hex messages with a trailing checksum byte; responses return success data or an ERR1/ERR2 error code pair.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # TCP port stated in source (section "Port number")
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 bps as configurable; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  communication_mode: full_duplex  # stated as "Full duplex"
  flow_control: null  # UNRESOLVED: flow control not stated in source (RTS/CTS pins wired on D-SUB 9P but software flow control policy not documented)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable     # inferred from 015 POWER ON / 016 POWER OFF commands
  - routable      # inferred from 018 INPUT SW CHANGE / 319-10 AUDIO SELECT SET
  - queryable     # inferred from extensive status-request commands (009, 037, 078-*, 097-*, 305-*)
  - levelable     # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 030-15 OTHER ADJUST
  - shutterable   # inferred from 051 SHUTTER CLOSE / 052 SHUTTER OPEN

Actions

# All payloads are hexadecimal byte sequences verbatim from source.
# <ID1> <ID2> <CKS> are framing parameters documented in section 2.2.
# Checksum (CKS) = low-order one byte of the sum of all preceding bytes (section 2.2).

Events

# UNRESOLVED: source documents no unsolicited notifications. All responses are
# solicited replies to commands (success or ERR1/ERR2 error frame).

Macros

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

Safety

confirmation_required_for:
  - power_off  # initiates cooling cycle; no other command accepted during cooldown
interlocks:
  - "Power On: while turning on, no other command accepted (section 3.2)."
  - "Power Off: during turn-off including cooling time, no other command accepted (section 3.3)."
  - "Error status bitfield (command 009) reports interlock switch open (DATA09 Bit1) and cover errors."
  # UNRESOLVED: full power-on sequencing / warmup timing not stated in source.

Notes

  • Checksum algorithm (section 2.2): CKS = low-order one byte (8 bits) of the sum of all preceding bytes. Worked example: 20h+81h+01h+60h+01h+00h = 103h -> CKS=03h.
  • Message framing: commands begin with a type byte (00h-03h); success responses echo with bit5 set (20h/21h/22h/23h); error responses use Axh prefix (A0h/A1h/A2h/A3h) followed by <ID1> <ID2> and a 02h-length ERR1 ERR2 CKS body.
  • ID1 (Control ID) and ID2 (Model code) are per-device framing parameters; ID2 varies by model. <CKS> is always the trailing checksum byte.
  • Error codes (section 2.4) are an ERR1/ERR2 pair (e.g. 00h/00h = command unrecognized; 02h/0Dh = command rejected because power is off; 02h/0Fh = no authority for operation). Full table in source.
  • Signal list number returned by input status is offset by -1 (add 1 for practical value).
  • Usage-time fields (lamp/filter) are in seconds, updated at one-minute intervals; lamp remaining life (%) is negative once the replacement deadline is exceeded.
  • Baud rate is configurable across 115200/38400/19200/9600/4800 bps; default not stated.
  • Input-terminal value tables, eco-mode values, aspect values, base-model-type values, and sub-input setting values are referenced to an Appendix ("Supplementary Information by Command") not present in this refined excerpt — marked UNRESOLVED where they affect a payload byte.

Spec done. 53 source commands enumerated — 25 actions + 28 queries. All hex payloads verbatim incl. checksum bytes. Both transports populated (TCP port 7142 + RS-232 config from §1.2). UNRESOLVED markers on: firmware ver, default baud, flow_control, appendix enum tables (input-terminal/eco/aspect/base-model/sub-input), warmup timing.

## Known Gaps

```yaml
- "exact model-name string returned by 078-5 MODEL NAME REQUEST not shown for this device. Firmware version compatibility and protocol version not stated. Voltage/power specs not covered by this command reference."
- "flow control not stated in source (RTS/CTS pins wired on D-SUB 9P but software flow control policy not documented)"
- "query device at runtime via gain_parameter_request_3"
- "source documents no unsolicited notifications. All responses are"
- "source documents no multi-step command sequences."
- "full power-on sequencing / warmup timing not stated in source."
- "firmware/protocol version not stated. Default baud rate not stated. Full input-terminal / eco-mode / aspect / base-model / sub-input enum tables live in an appendix absent from this excerpt. Wireless-LAN unit specifics deferred to the operation manual."
