interlocks:
  - "Power On command requires UART Wake On to be enabled on the display. If disabled, Power On command has no effect."

Notes

Source documents RS-232 hex protocol only; no TCP/IP framing documented despite operator hint. XOR check bit (xx) varies per screen_id; consult manufacturer docs for computation routine. NAV_REMOTE commands broadcast to all devices (no screen_id). Volume range 0–100 decimal (0x00–0x64). Power State Query response byte 01 = Off, 02 = On.

summary: "All 40 spec action frames match the source RS-232 hex frames exactly, transport values are supported, and the source has no additional commands. (5 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "TCP/IP control not documented in source despite being listed as known protocol; this spec covers RS-232 only. Firmware version compatibility range not stated."
- "source does not document discrete settable parameters outside of action commands"
- "source does not document unsolicited notifications"
- "source does not document multi-step sequences"
- "TCP/IP control interface not documented in source; XOR check bit computation algorithm not documented in source; firmware version compatibility range not stated."
