Summary

Projector control spec for the Sharp/NEC LD Fa152 F, based on the vendor Projector Control Command Reference Manual (BDT140013 Rev 7.1). The device is controllable over RS-232C serial and wired/wireless LAN (TCP). Commands are binary hex frames; responses carry a success/error prefix, the projector's control ID and model code, and a trailing checksum byte. This spec enumerates all 53 documented commands.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # all supported per source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow-control mode not stated; RTS/CTS pins are wired in the D-SUB 9P pinout (pin 7 RTS, pin 8 CTS) but the communication-conditions table lists only baud/data/parity/stop/full-duplex
addressing:
  port: 7142  # TCP port for command send/receive over LAN
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 (brightness/contrast/color/hue/sharpness), LAMP ADJUST present

Actions

# Frame format (sent): fixed hex bytes; parameterized DATA fields shown as <DATA##>.
# Trailing <CKS> = checksum = low-order byte of the sum of all preceding bytes.
# Command sent frames do NOT carry ID1/ID2; those appear only in responses.
# Response success prefix mirrors command type (00h->20h, 01h->21h, 02h->22h, 03h->23h);
# error prefix is A0h/A1h/A2h/A3h with <ERR1> <ERR2>.

Safety

confirmation_required_for: []
interlocks: []
# Source notes command-acceptance interlocks (not safety interlocks per se):
#  - POWER ON: while turning on, no other command accepted.
#  - POWER OFF: during power-off incl. cooling time, no other command accepted.
#  - Several commands rejected with ERR 02h/0Dh when power is off.
# No voltage/current/power, lamp-handling, or power-on sequencing safety warnings present in the refined source.

Notes

  • Frame format: commands are binary hex. Sent frames do not include ID1/ID2; responses do (<ID1> = projector control ID, <ID2> = model code).
  • Checksum (CKS): low-order one byte of the sum of all preceding bytes. Example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Response prefixes: success = 20h/21h/22h/23h (mirrors command type 00h/01h/02h/03h); error = A0h/A1h/A2h/A3h carrying <ERR1> <ERR2>.
  • Serial: RS-232C cross cable to PC CONTROL port (D-SUB 9P); pins 2 RxD, 3 TxD, 5 GND, 7 RTS, 8 CTS.
  • LAN: wired (RJ-45, 10/100 Mbps auto) or wireless LAN unit; TCP port 7142.
  • Lens control: after a continuous-drive (7Fh/81h) lens_control, send 00h to stop.
  • Usage-time granularity: lamp/filter usage returned in seconds, updated at 1-minute intervals.

Spec output above. 53 commands cataloged verbatim from source. Binary hex payloads carried in `command:` field; `<CKS>` checksum rule + frame format documented in Notes. Serial + TCP both populated (port 7142 + full RS-232C config explicitly stated). Appendix enum tables (input/aspect/eco/base-model/sub-input) absent from refined source → marked UNRESOLVED, no values fabricated.

## Known Gaps

```yaml
- "exact marketing model string not printed in the source text (only doc number BDT140013 Rev 7.1); model taken from device metadata."
- "firmware compatibility range not stated."
- "input-terminal / aspect / eco-mode / base-model-type / sub-input value tables live in an \"Appendix: Supplementary Information by Command\" that is not present in the refined source; those enum values are not captured here."
- "flow-control mode not stated; RTS/CTS pins are wired in the D-SUB 9P pinout (pin 7 RTS, pin 8 CTS) but the communication-conditions table lists only baud/data/parity/stop/full-duplex"
- "flow_control mode not explicitly stated (RTS/CTS wired but not listed in comm table)."
- "input-terminal, aspect, eco-mode, base-model-type, and sub-input value enums live in an Appendix (\"Supplementary Information by Command\") absent from the refined source."
- "default baud rate among the five supported values not stated."
- "exact model marketing string not printed in source body."
```
