Variables

# UNRESOLVED: no discrete settable parameters beyond dimmer and presets

Events

# UNRESOLVED: no unsolicited event format documented besides rs232_update mode

Macros

# UNRESOLVED: no multi-step macros documented

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no safety warnings or interlock procedures in source

Notes

RS-232 hardware does not support flow control. Avoid packet loss by not overwhelming the device. Commands: no spaces, no carriage return/line feed after "!". Responses: "$" for fixed length, "$$" for variable length (station metadata). Play-Fi provides source feedback only — transport status not reported.
