Feedbacks

# UNRESOLVED: response format for query commands not documented in source
# Source describes query commands (/*Type;, /^Version;, S[x], Status[x1], Status)
# but does not document the response format/structure

Variables

# No continuous variables identified. All commands are discrete actions/queries.

Events

# No unsolicited notification events documented in source.

Macros

# Source shows multi-command chaining example (e.g. "1B7.2A4." = route AV 1→7 then audio 2→4)
# but does not define named macro sequences.

Safety

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

Notes

Command codes work in both ASCII and HEX format.
Multiple commands can be chained in a single transmission separated by periods (e.g. 1B7.2A4.).
Password is 8-digit numeric, used for front panel control panel — serial commands do not require authentication.
Two alternative command syntaxes exist for routing: [x1]B[x2] and [X1]*[X2]! for AV, [x1]A[x2] and [X1]*[X2]$ for audio, [x1]V[x2] and [X1]*[X2]%/[X1]*[X2]& for video.
AV16 series has optional TCP/IP Ethernet (RJ-45) but port number not documented.
