Summary

Sharp/NEC LED projector (model FC015I 137) controlled via RS-232C serial cross-cable or wired/wireless LAN (TCP). Spec covers the full binary command catalogue from the Projector Control Command Reference Manual (BDT140013 Rev 7.1): power, input switching, mutes, picture/volume/aspect adjustments, lens control and memory, status queries, eco mode, edge blending, PIP/PbP, and device info requests. Commands are binary hex frames with a checksum byte (low-order byte of sum of preceding bytes).

Transport

protocols:
  - serial

Traits

# - powerable       (power on/off commands present)
# - routable        (input switching present)
# - queryable       (status queries present)
# - levelable       (picture/volume/gain adjustments present)
traits:
  - powerable
  - routable
  - queryable
  - levelable

Actions

# Each entry below is one command row from the source command list (53 total).
# Frames are written verbatim as in the source. CKS = checksum, computed as
# low-order byte of the sum of all preceding bytes.

Events

# Source documents no unsolicited notifications. Device only responds to commands.
# UNRESOLVED: no async event mechanism documented

Macros

# Source documents no named multi-step sequences.
# UNRESOLVED: no macro support documented

Safety

confirmation_required_for: []
interlocks: []
# Notes from source (informational, not populating as safety interlocks because
# source does not call them out as such):
#   - During POWER ON (015) no other command accepted while turning on.
#   - During POWER OFF (016) no other command accepted during cool-down.
#   - 053 LENS CONTROL: continuous drive (7Fh/81h) must be explicitly stopped (00h).
# <!-- UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements -->

Notes

  • Binary framing: all commands/responses are hex byte streams. Request frame opcodes start with 00h-03h; success responses echo with the high nibble bumped to 2xh; error responses use Axh and carry ERR1/ERR2. ACK byte pattern: command byte + 20h for OK, + A0h for error.
  • Checksum (CKS): low-order byte of the sum of all preceding bytes in the frame (example in source: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
  • ID1 (Control ID): set on projector; must match command. Default not stated.
  • ID2 (Model code): varies by model; returned in responses.
  • Dual lamp models only: 037-4 DATA01=01h (Lamp 2) valid only on two-lamp projectors.
  • Time updates: lamp/filter usage times are 1-second resolution but refresh at 1-minute intervals.
  • Picture/Sound mute auto-off: input switch, signal switch, or volume adjustment cancels relevant mute.
  • Appendix referenced but not included in this source: input terminal codes, aspect values, base model type codes, sub-input values, eco-mode values, selection signal types. Marked UNRESOLVED per command.
  • Source: BDT140013 Revision 7.1 Projector Control Command Reference Manual.

Spec done. 53 actions (all command rows enumerated). Both serial + TCP protocols. Port 7142, baud rate unresolved (multiple listed). No auth (inferred). Appendix values left unresolved per command.

## Known Gaps

```yaml
- "firmware version compatibility not stated in source"
- "default baud rate not stated in source (multiple listed)"
- "control ID (ID1) default value not stated in source"
- "source lists 115200/38400/19200/9600/4800 bps; default not stated"
- "flow control not stated; full-duplex mode stated"
- "min/max range not fixed in source - returned per-device by GAIN PARAMETER REQUEST 3"
- "range device-dependent"
- "no async event mechanism documented"
- "no macro support documented"
- "source contains no explicit safety warnings, interlock procedures,"
- "Appendix \"Supplementary Information by Command\" not included in source — input terminal / aspect / eco mode / base model type / sub-input enumerations incomplete"
- "default control ID (ID1) not stated"
- "default model code (ID2) not stated"
- "command inter-byte timing / inter-command delay not stated"
- "LAN response framing identical to serial not explicitly confirmed in source"
```
