Variables

# All settable parameters captured in Actions above; queryable state returned via Feedbacks.
# No separate Variables section required.

Events

# UNRESOLVED: No explicit event/push notification descriptions in source.
# Device responds to commands; no unsolicited events documented.

Macros

# No explicit multi-step macros described in source.

Safety

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

Notes

RS-232 pass-through commands (C, H, T) and boot loader commands (B) require V1.07+. Version query returns sw=X.XX hw=X.XX. Reset command returns <DCM-1 RESET/> response before rebooting. Error responses use prefix ! plus uppercase letter. No password or authentication required.
