Notes

Protocol is case-sensitive ASCII. Command frame: S{CLIENT ID(3)}{COMMAND(4)}{DATA(4)}{CHECKSUM(1)}{CR}. Query frame: Q{CLIENT ID(3)}{COMMAND(4)}????{CHECKSUM(1)}{CR}. Client ID for Smart TV is last 3 bytes of Ethernet MAC address; broadcast uses ALL. Acknowledgements: OKAY, EROR, WAIT. Checksum is 8-bit ensuring full frame sums to zero. RS-232 port must be enabled via Custom Install menu (7-3-1-0 remote code sequence) before serial control works. Power-on via RS-232 requires Power On Command setting enabled in the same menu. No authentication, no login required.

Verification Summary

verdict: verified

matched_actions: 118
action_count: 118
confidence: medium
summary: "All 118 spec action units (87 set-commands + 31 query feedbacks) match verbatim mnemonics in the source RS-232 command table; transport parameters confirmed; source command catalogue fully represented. (4 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "TCP/IP control not documented in source — only RS-232"
- "no unsolicited event notifications described in source"
- "no multi-step macro sequences described in source"
- "power-on sequencing via RS-232 requires RS-232 Remote Power On setting to be enabled in Custom Install menu; source does not specify voltage/current/power specs"
