AI4AVSummary
NEC projector supporting both serial (RS-232C) and wired TCP/IP control. Communication settings include configurable baud rates from 4800 to 115200 bps, 8 data bits, no parity, 1 stop bit, full duplex. LAN control uses TCP port 7142. No authentication required for either interface.
Transport
protocols:
- serial
- tcp
addressing:
port: 7142 # stated: "Use TCP port number 7142"
serial:
baud_rate: null # UNRESOLVED: baud rate configurable (115200/38400/19200/9600/4800 bps) but none fixed in source
data_bits: 8 # stated: "Data length 8 bits"
parity: none # stated: "Parity bit None"
stop_bits: 1 # stated: "Stop bit 1 bit"
flow_control: null # UNRESOLVED: hardware flow control pins present (RTS/CTS) but no protocol stated
auth:
type: none # inferred: no auth procedure in source
Traits
- powerable # inferred: POWER ON (015) and POWER OFF (016) commands present
- routable # inferred: INPUT SW CHANGE (018) command present
- queryable # inferred: multiple status request commands present (ERROR STATUS, RUNNING STATUS, INPUT STATUS, MUTE STATUS, etc.)
- levelable # inferred: PICTURE ADJUST (030-1), VOLUME ADJUST (030-2), ASPECT ADJUST (030-12) commands present
