Traits

- powerable       # inferred from PW and SR commands
- queryable       # inferred from Get-state commands (ST, LO, BG, OL, CH, CU, AV, AM, AT, XC, XP, SC)
- levelable       # inferred from AV audio-volume set commands
- routable        # inferred from CH (video source per channel) and MC (macro) commands

Actions

# Frame format: 0x55 0xF0 LEN ADDR ACTION CMD(nx2) PARAMS 0x0D
# ACTION: 0x67=Get, 0x73=Set, 0x06=ACK, 0x15=NAK
# Default ADDR 0x01 used in source examples. Address range 0x01-0xFF (0 reserved).
# All lengths in source examples use address 0x01; LEN = ADDR+ACTION+CMD+PARAMS bytes.

Notes

• Frame: 0x55 0xF0 LEN ADDR ACTION CMD(nx2) PARAMS 0x0D. Extended header 0xF0 explicitly noted as "no checksum in format".
• Action byte: 0x67=Get, 0x73=Set, 0x06=ACK, 0x15=NAK. Address 0x01-0xFF; 0 reserved. Source flags address as "reserved for future use. Don't care".
• NAK returned both for "command failed" and "received invalid protocol data" (with End only).
• Source title explicitly covers both LC300 and LC300S; protocol identical for both.
• Standby mode (SR 0x31): source states "only accept command including 'Get state' and 'Set Standby/Wakeup'". All other commands are rejected until wake.
• Boot-up: source notes "Commands are not accepted during media station boot-up."
• TCP connection: per source, "If connection is not closed by client, connection will keep and get event notification until new connection established."
• Stream and Video Source ID parameter ranges are described in source as "based on web setting" (dynamic), not fixed maximums.
• Audio Type source quirk: inputs 1-4 only accept 0x3A (Follow); input 5 only 0x37/0x38; input 6 only 0x31/0x41; inputs 7-8 unsupported.
• Set Power (PW 0x31) is documented but flagged "NOT supported. Hardware limitation".
• Get Overlay source shows range 0x00-0x09 in the response table (likely source-side typo vs. Set Overlay's 0x00-0x1E range); recorded as-stated.

summary: "All 43 spec actions matched literal source commands with correct shapes; transport fully verified; source command set fully represented. (4 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "firmware compatibility range; source does not state it."
- "source models all settable parameters as discrete actions (e.g. AV set volume per input), not as named variables"
- "source exposes 9 macro slots via MC command but does not document macro definition, sequence, or content"
- "source does not state firmware compatibility range, voltage/current/power specs, fault-recovery sequences, protocol version, default credentials, or NAK retry/recovery procedure."
