Variables

# UNRESOLVED: all settable parameters are represented as Actions with direct commands
# No separate Variables section needed - parameters exposed via direct set commands

Events

# UNRESOLVED: device sends unsolicited notifications; VISCA supports event-like replies
# but source does not document event subscription mechanism

Macros

# UNRESOLVED: source describes no named multi-step macros

Safety

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

Notes

Camera address in VISCA packets: X = 9 to F (camera address + 8), controller address is 0 (broadcast header 88h)
VISCA over IP uses UDP port 52381; delivery confirmation is application-level responsibility
RS232 over IP supports up to 5 simultaneous controllers on same LAN segment
Broadcast function not available for VISCA over IP
PelcoD protocol: checksum = Mod(Byte2+Byte3+Byte4+Byte5+Byte6, 0x100); internal and external command lists provided
Source also covers CV420-30X-IP; this spec covers CV355-30X-IP specifically
Audio delay range: 1 to 500ms (hex 0x001 to 0x1F4)
HDMI YUV422 format only available at 4K60P/4K59.94P/4K50P

Verification Summary

verdict: verified
checked_at: 2026-05-14T18:17:18.110Z
matched_actions: 130
action_count: 166
confidence: medium
summary: "All 130 spec actions matched VISCA and PelcoD source commands; transport verified. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "PelcoD external command list may require separate protocol implementation; not clear if both VISCA and PelcoD can operate simultaneously or if切换 is required"
- "all settable parameters are represented as Actions with direct commands"
- "device sends unsolicited notifications; VISCA supports event-like replies"
- "source describes no named multi-step macros"
- "no safety warnings or interlock procedures in source"
- "whether both VISCA and PelcoD can operate simultaneously on different interfaces not stated"
- "port 52381 stated for RS232 over IP; whether VISCA over IP uses same port or different port not explicitly separated in source"
