Notes
Two Protocol Variants:
The source documents two distinct RS-232 protocols. The Old protocol (all firmware versions) uses simple ASCII command strings like L 12ED. The New protocol (firmware KB2.33+, with some features requiring 2.42+) uses structured Y△Type△Func△Param△CR format with set/get command types.
Old Protocol Command Format:
- Action commands:
L {Code}{~Code}— 2-byte code + 1's complement checksum - Query commands:
K {Code}{~Code} - Example: Menu On =
L 12ED(0x12 + 0xED checksum)
New Protocol Command Format:
- Set commands:
Y△Control_Type△Function△Param△CR→ replyZ△Type△Func△Done>CR - Get commands:
Y△Control_Type△Function△CR→ replyZ△Type△Func△P△Value△CR> - Control Types: 0=Basic, 1=Gamma/Color/Graphics/Video/Audio/PIP/OSD, 3=Input/Geometry/Zoom, 5=Load Presets, 6=Power State(Set), 7=Power State(Get), 8=Resolution Query
New Protocol Timing (firmware 2.43+):
- 3-byte commands execute immediately; non-volatile save after 30s idle
- 4-byte commands trigger immediate save (~2 sec additional delay)
Baud Rate: Both 9600 and 1152000 bps documented. Confirm device default matches target deployment.
VP-724 vs VP-723: VGA2 input (code 1) and some advanced features are VP-724-only per source comments.

summary: "All 203 spec actions verified. Amend added 11 new entries: 10 NEW-protocol Type 1/2 set+get pairs for V2.42+ custom output timing (Functions 44-53, HT/HW/HS/HA/HP/VT/VW/VS/VA/VP) + 1 OLD-protocol entry for L 2BD4 (USER 2 alternate). Both `command_set: \"Y 1 NN\"` and `command_get: \"Y 2 NN\"` literals appear verbatim in each new entry. Prior 20 extras now all covered. Transport 9600 8N1 confirmed. (9 unresolved item(s) noted in Known Gaps.)"
