Feedbacks

# Response codes documented in source:
#   "OK" + CR  (0DH) - normal response
#   "ERR" + CR (0DH) - problem response (communication error or incorrect command)

- id: response_normal
  type: string
  values: ["OK"]
- id: response_error
  type: string
  values: ["ERR"]

Variables

# UNRESOLVED: settable parameters are exposed as discrete Actions in the source,
# not as free-form variables. No standalone Variables block documented.

Events

# UNRESOLVED: source does not document unsolicited notifications from the TV.

Macros

# UNRESOLVED: source does not document multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements beyond the RSPW2 standby-mode note.

Notes

Command format: 8 ASCII bytes total = C1 C2 C3 C4 (4-char command) + P1 P2 P3 P4 (4-char parameter, left-aligned, padded with blanks). Terminated by CR (0DH).

Do NOT send multiple commands simultaneously. Wait for "OK" response before sending next. Connection auto-disconnects after 3 minutes of no IP communication.

"x" in parameter column means any digit; "_" means a literal space; "*" means a value from the documented range.

For IP: Service must be set to None (not Telnet or SSH). ID/password may be required if configured on TV menu.

RSPW (Power On Command Setting) parameter 2 keeps the command in waiting status when TV is in standby — power consumption similar to usual, and the Center Icon Illumination on the TV front lights up while commands are queued.
