Summary
Sharp/NEC LED FA025I2 projector control spec. Binary hex command protocol over both RS-232C serial and TCP/IP (wired/wireless LAN). Commands use framed hex payloads with checksum byte; responses carry ID1/ID2 plus data or error codes.
Transport
protocols:
- tcp
- serial
addressing:
port: 7142 # "Use TCP port number 7142 for sending and receiving commands."
serial:
baud_rate: 115200 # source lists 115200/38400/19200/9600/4800 bps as selectable; 115200 shown first
data_bits: 8
parity: none
stop_bits: 1
flow_control: none # full-duplex communication mode stated; no flow-control field in source
auth:
type: none # inferred: no auth procedure in source
Traits
- powerable # inferred: POWER ON (015) / POWER OFF (016) commands present
- queryable # inferred: many status/information request commands present
- levelable # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST present
Actions
# All command payloads verbatim from source (hex bytes). ID1/ID2/CKS appear in
# the framed protocol; literal command bytes below are exactly as documented.
# Checksum (CKS) = low byte of sum of all preceding bytes.

Notes
- Baud rate is selectable among 115200/38400/19200/9600/4800 bps; 115200 listed first (likely default). Both endpoints must match.
- Command frame: literal hex bytes; checksum (CKS) = low-order byte of sum of all preceding bytes.
- Response frame prefixes:
20h/21h/22h/23h= success (echoes command group),A0h/A1h/A2h/A3h= error response with ERR1/ERR2. - ID1 = projector control ID setting; ID2 = model code (model-specific).
- Lamp/filter usage times update at one-minute intervals despite one-second resolution.
- Two-lamp projector models only: Lamp 2 selectors (DATA01=01h) effective.
Spec done. 53 commands, all hex payloads verbatim. Serial+TCP both documented, port 7142 explicit, no auth inferred. Appendix value tables referenced but absent → marked UNRESOLVED.
