Summary

The Extron PVS 407D is a PoleVault Digital Switcher with Ethernet Control designed for classroom AV systems. It provides 7-input video and audio switching with HDMI/HDBaseT outputs, EDID Minder, HDCP management, integrated VoiceLift Pro microphone system support, and audio DSP features including feedback suppression and paging. Control is via Extron Simple Instruction Set (SIS) over RS-232 (9600 baud, 8N1) or Ethernet (Telnet port 23).

Traits

traits:
  - routable    # inferred: input selection commands (X! selects input 1-7)
  - queryable   # inferred: extensive query commands (input, volume, status, EDID, HDCP, etc.)
  - levelable   # inferred: volume control (set/increment/decrement), pixel phase, picture adjustment

    Switcher sends unsolicited tagged responses via Ethernet/USB/RS-232 whenever
    there is any state change on the VoiceLift receiver (VLR 302 or VLR 102).
  trigger: voicelift_state_change

Macros

# No multi-step command sequences explicitly described in the source.

Safety

confirmation_required_for: []
interlocks: []
# NOTE: The source documents several destructive reset commands that should be
# used with caution (not explicitly flagged as safety interlocks in source):
#   - E ZXXX  - resets all video and audio settings to factory defaults
#   - E ZQQQ  - absolute system reset to factory defaults (firmware retained)
#   - E 1ZQQQ - IP system reset (resets IP/network settings to factory defaults)
#   - E ZFFF  - erases all files from flash user memory (EDID, configs, HTML)
#   - E ZY    - absolute system reset, retains IP settings
#   - E v1*1RSTD - VoiceLift receiver factory reset (clears microphone pairing)
# No explicit safety warnings, interlock procedures, or power-on sequencing
# requirements are documented in this source.

Notes

  • SIS command structure: Commands consist of one or more characters per field. No special characters required to begin or end a command. All responses end with CR/LF (represented as ] in the source). A space (•) marks required spaces only.
  • Verbose mode: Four modes (0–3). Mode 0 = clear/none (default for IP). Mode 1 = tagged responses for queries. Mode 2 = tagged responses (default for RS-232/USB). Mode 3 = verbose + tagged. When tagged responses are enabled, all read commands return the constant string plus data.
  • Audio mute behavior: The 1Z mute command affects embedded HDMI, line out, and amplifier outputs. If output audio mute is on and input is switched or volume changed, the switcher auto-unmutes. Audio file playback is excluded from the Z mute command.
  • Password behavior: Reading a password via RS-232 or IP returns four asterisks (****) if a password exists, empty if none set — never returns the actual password.
  • VoiceLift receiver detection: Returns E25 (device not present) when VLR 302/VLR 102 is not detected. Returns E14 when VLR 102 is detected but VLR 302 command was sent.
  • Error codes: E01 (invalid input channel), E10 (invalid command), E12 (invalid port), E13 (invalid parameter), E14 (invalid for configuration), E17 (invalid for signal type), E18 (timeout), E22 (busy), E24 (privilege violation — administrator level required), E25 (device not present), E26 (max connections exceeded), E28 (file not found).
  • Default network settings: IP 192.168.254.254, subnet 255.255.0.0, gateway 0.0.0.0, DHCP off, Telnet port 23, Pass-Thru port 2003.
  • GVCCS audio streaming: Requires firmware 5.00+ and Audio Decoding LinkLicense. Default multicast 239.255.255.250, UDP ports 3030 (public), 2020 (priority), 3029 (listen).

Verification Summary

verdict: verified
checked_at: 2026-07-12T08:59:04.771Z
matched_actions: 153
action_count: 153
confidence: medium
summary: "Every one of the 153 spec action/feedback commands matches a literal SIS command row in the source with correct shape, and every source command-table row is represented in the spec; transport params match exactly. (4 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "firmware version compatibility ranges not stated in source beyond feature-specific notes (2.00+ for 4K/UHD, 5.00+ for GVCCS audio streaming)"
- "firmware version compatibility ranges beyond feature-specific notes (2.00+, 5.00+)"
- "maximum number of concurrent TCP/IP connections not stated (E26 implies a limit exists)"
- "RS-232 control port is a 3.5mm captive screw 3-pole connector (Tx, Rx, G) — wiring documented but connector spec not beyond that"
