Notes

Protocol frames packets as: SOH | Reserved('0') | DestAddr | SrcAddr('0' for controller) | MsgType | Length | STX ... ETX | BCC | CR. BCC = XOR of D1..D16 bytes. Delimiter fixed as CR (0Dh). All message-body byte values are encoded as ASCII hex (e.g. 3Ah → '3A'). Monitor-ID-to-DestAddr mapping: ID 1→'A'(41h) ... ID 25→'Y'(59h), ID 26→'Z'(5Ah), IDs 26-100 continue hex sequence; ALL monitors → '*'(2Ah). Group ID A-J maps to '1'-':' (31h-3Ah). Default timeouts: 10 seconds. Power modes per CTL-01D6: 0001H=ON, 0002H=Stand-by (power save), 0003H=Reserved, 0004H=OFF (same as IR power off). Manual covers 12 SKUs (PN-M432/M502/M552/M652/P436/P506/P556/P656/M752/M862/M982/P756) — per-model feature availability not enumerated in source.

summary: "All 108 spec actions carry wire-literal VCP/CTL opcodes that appear verbatim in the source's chapter-7 CTL list and chapter-8 OSD command table; shapes and transport parameters agree. (6 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "device-specific model coverage — source manual is shared across 12 SKUs; per-model feature support not enumerated"
- "not applicable - VCP/CTL protocol exposes all settable parameters as discrete action commands; no separate Variables layer needed"
- "source describes only request/response framing; unsolicited push events not documented"
- "source does not document multi-step macro sequences"
- "source does not document electrical safety warnings or hardware interlocks beyond the inter-command timing intervals above"
- "firmware version compatibility ranges, error recovery sequences, and per-model command support gaps are not specified in source"

Verification Summary

verdict: verified checked_at: 2026-08-05T08:40:47.359Z matched_actions: 108 action_count: 108 confidence: medium summary: "All 108 spec actions carry wire-literal VCP/CTL opcodes that appear verbatim in the source's chapter-7 CTL list and chapter-8 OSD command table; shapes and transport parameters agree. (6 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "device-specific model coverage — source manual is shared across 12 SKUs; per-model feature support not enumerated" - "not applicable - VCP/CTL protocol exposes all settable parameters as discrete action commands; no separate Variables layer needed" - "source describes only request/response framing; unsolicited push events not documented" - "source does not document multi-step macro sequences" - "source does not document electrical safety warnings or hardware interlocks beyond the inter-command timing intervals above" - "firmware version compatibility ranges, error recovery sequences, and per-model command support gaps are not specified in source"
