Variables

# UNRESOLVED: no discrete settable parameters beyond action commands; raw positions
# (zoom, focus, pan, tilt) are queryable but are typically treated as actions.

Events

# Push messages are listed under Feedbacks (network_change_push, ir_push).

Macros

# UNRESOLVED: no multi-step sequences described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety warnings, interlock procedures, or power-on
# sequencing requirements in source. PT_Limit_Set is described as session-only
# (clears on reboot) but that is operational, not safety-critical.

Notes

Codec (host) sends on address byte 0x81; camera replies on 0x90. Single-camera use typically address 0x81, broadcast 0x88.
PrecisionHD 1080p supports a single socket only (Y=0 in 0x5Y/0x6Y replies). Command_Cancel should not be used on that model.
CAM_Speed reply is sent before the baud switch; wait 20 s after OK before sending new commands.
CAM_Boot resets serial speed back to 9600.
SW_packet and CAM_PingPong_Reset / CAM_Ping / CAM_Stdin messages must never be routed through Sony cameras (exceed 16 bytes or violate VISCA length).
PTZF_Direct, CAM_SWID_Inq, SW packet, SW start, SW end, SW abort also exceed 16 bytes and must be placed first in daisy chain.
Commands marked with * in source do not apply to PrecisionHD 1080p4x, 1080p2.5x, or Precision 40.
PrecisionHD 720p commands are documented in a separate MXP Reference User Guide for System Integrators.
Wait 9 s after receiving Network_Change push before full reconfigure.

Verification Summary

verdict: verified
checked_at: 2026-06-02T21:41:14.974Z
matched_actions: 94
action_count: 94
confidence: medium
summary: "All 94 spec actions have literal matches in source; transport parameters verified; comprehensive coverage of command catalogue. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "per-model applicability of asterisk-marked commands is in the source but not encoded per action."
- "no input routing commands in source"
- "no volume/gain control in source"
- "no discrete settable parameters beyond action commands; raw positions"
- "no multi-step sequences described in source."
- "no explicit safety warnings, interlock procedures, or power-on"
- "firmware version compatibility ranges not stated in source. Per-model applicability of asterisk-marked commands is not encoded per action (one source flag, many models)."
