Extron DSC HD-HD 4K A Series Control Spec

Summary

Extron DSC HD-HD 4K A Series 4K scaling converters (DSC HD-HD 4K A, DSC HD-HD 4K PLUS A, DSC HD-HD 4K PLUS A xi), controlled via Extron SIS (Simple Instruction Set) over RS-232, front-panel USB, or Ethernet LAN. Covers the full SIS command/response table from User Guide 68-2803-01 Rev. E.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 23  # Telnet/SIS port default per source (reset to 23 via "E 23 MT }"); web port 80, SNMP 161
  base_url: ""  # N/A - SIS is Telnet/serial framing, not HTTP
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: password  # password prompt after copyright banner; admin or user level
  # Factory default password = device serial number (case-sensitive).
  # After absolute system reset (E ZQQQ } or mode 5 reset) password resets to "extron".

Notes:

• SIS framing: no begin/end delimiters; responses end with CR/LF (denoted ] in source); } = CR with no LF; E = Escape char; • = Space.
• USB mini-B config port (front panel) carries the same SIS command set.
• All commands case-insensitive unless otherwise stated.

Traits

traits:
  - queryable  # inferred: many view/query commands (X! *I, Q, N, E 1 CONT }, etc.)
  - levelable  # inferred: contrast/brightness/detail/volume/gain/shift/size settable
  - powerable  # inferred: power save on/off commands present (E 1 PSAV })

Actions

# All command payloads verbatim from source Command and Response Table.
# Symbols preserved: E=Escape, }=CR(no LF), ]=CR/LF, •=space, X<n>(<c>)=parameter placeholders.

  - "Rear-panel Reset mode 1 reverts firmware for one power cycle only; Extron warns DO NOT operate in that state."

Notes

• Three models share this spec: DSC HD-HD 4K A (60-1573-03), DSC HD-HD 4K PLUS A (60-1573-01), DSC HD-HD 4K PLUS A xi (60-1573-02). xi model adds input B, output B, left-right column mode, buffered output mode, and 4096x2160 column EDID.
• SIS framing tokens (verbatim): • = space, ] = CR+LF, } = CR (no LF), E = Escape. Preserve in command payloads.
• Verbose mode (X3!) changes many query response shapes — tagged variants shown in source under "verbose modes 2 and 3" rows. Default: verbose on for RS-232/USB, off for LAN.
• Error codes: E01 invalid input, E10 invalid command, E11 invalid preset, E12 invalid port, E13 invalid parameter, E14 invalid for config, E17 invalid for signal type, E22 busy, E24 privilege violation, E28 bad filename, E33 bad file type/size. Unknown commands receive no response at all.
• EDID rate-code table and Output Resolution/Refresh table (X2! codes 10..203) are large enumerations documented in source lines 60–191; not duplicated here per granularity rule (one parameterized set_output_rate action covers the range).
• Custom output rates (201/202/203) limited to 300 MHz pixel clock; supported only as buffered outputs (xi model).

Spec done. ~210 actions enumerated (every command table row). Serial+TCP transport, password auth (factory = serial number). Traits queryable+levelable+powerable. Events, feedbacks, variables, safety all populated from source. UNRESOLVED markers on firmware range, OSD menu emulation set (page 64 not in extract), voltage/power specs.

## Verification Summary

```yaml
verdict: verified
checked_at: 2026-06-16T07:05:18.285Z
matched_actions: 213
action_count: 213
confidence: medium
summary: "All 213 spec actions have verbatim command matches in the source command table; transport (9600 baud, port 23, password auth) fully supported; source command catalogue fully represented. (6 unresolved item(s) noted in Known Gaps.)"
```

## Known Gaps

```yaml
- "firmware version compatibility range not stated in source. Voltage/power specs not in this extract. xi-model-only commands (input B, output B, column mode) are flagged where relevant."
- "no multi-step sequences explicitly described as macros in source."
- "firmware version compatibility range not stated."
- "rear-panel Reset mode 1 full activation procedure is hardware-only (no SIS equivalent)."
- "OSD menu-emulation command set (E M...) referenced but full table is on source page 64, not in this extract."
- "voltage / current / power specs not present in this refined extract."
```
