Events

# UNRESOLVED: source does not describe unsolicited event notifications

Macros

# UNRESOLVED: no explicit multi-step macros described in source

Safety

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

Notes

Command protocol: binary with header 20h 88h <ID1> <ID2> 0Ch <DATA> <CKS>. Response: A0h/A2h/A3h prefix. Checksum = low-order byte of sum of all preceding bytes. Power-on command blocks other commands until power-on completes. Power-off command blocks until cooling complete. Lens drive-continue command (7Fh/81h) requires explicit Stop (00h) to halt.
