Feedbacks

# UNRESOLVED: device sends display data (OSD) back to controller - string-based
# display packets with 0xFE start byte, 0x17 count, 0xA0 device ID, 0x20 type,
# but no full decode of flag bits provided in source. Feedback section not
# populated due to incomplete flag decode documentation.

Variables

# UNRESOLVED: treble/bass are adjusted via increment/decrement commands only (no absolute set).
# No query commands returning current treble/bass values documented.

Events

# UNRESOLVED: unsolicited display data packets are documented (RSP1098→PC) but
# detailed flag decode not provided.

Macros

# UNRESOLVED: no multi-step macro sequences documented in source.

Safety

confirmation_required_for: []
interlocks:
  - Firmware note: some RS232 commands only available on units with serial #s beyond 079/979-3411001. Units before this serial require software update and EPROM.
# UNRESOLVED: no explicit safety warnings or interlock procedures for power sequencing.

Notes

Device supports two-byte byte-stuffing for any command string containing 0xFE or 0xFD: FD→FD 00, FE→FD 01. Used for Power On (FE→FD 01), Power Off (FD→FD 00 for checksum byte), Volume 43/44, Zone 2 Volume 40/41.

Main zone discrete commands (Type 14) recommended for multi-zone installations to avoid zone conflicts.
