Aurora Dxci 4 2V2H G2 Control Spec

Summary

The Dxci 4 2V2H G2 is a 4-input AV input card (2× VGA + 2× HDMI) for the Aurora DXM G2 Series matrix chassis. It has no standalone control interface; it is driven over the chassis main RS-232 control port. This spec documents the RS-232 serial command set of the parent DXM G2 chassis that governs this card (routing, presets, per-port serial pass-through, HDCP, hot-plug, DVI mode, baud configuration, and firmware/route queries).

Transport

protocols:

  parity: none  # from "8N1"
  stop_bits: 1  # from "8N1"
  flow_control: null  # UNRESOLVED: flow control not stated in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - routable  # inferred: route command examples present (!Rxtoz, !RTx1 x2 x3)
  - queryable  # inferred: query commands returning state present (?BR, ?RX, ?FM, ?R)

Notes

• Command vs query convention: ! = command (case sensitive), ? = query command (case sensitive), ~ = response (same case as the command).
• <CR> / <cr> = carriage return (hex 0x0D / decimal 13). Commands echo this literally.
• Timing: wait at least 250ms between commands (firmware version 2.2.6 and above). For older firmware, longer spacing may be required.
• RS-232 connector: DB-9 Female. Pin 2 = TX, Pin 3 = RX, Pin 5 = GND; all other pins N/A.
• Baud rate selectable via front panel; recommended/typical 115k 8N1 (max 115kbps). Per-card serial ports (input/output RS-232 pass-through) accept 2400–38400 only via !BR... commands.
• LAN port on rear panel is future-use; for LAN operation Aurora recommends using the Nugget Serial on the RS-232 port. No Ethernet control protocol documented.
• Scope caveat: this command set is the DXM G2 chassis protocol. The Dxci 4 2V2H G2 card occupies input card slots; card-specific analog/digital distinction affects firmware queries ("Firmware query commands do not work on analog cards").

Known Gaps

- "Source is the DXM G2 chassis manual excerpt, not a Dxci-specific document. The card itself has no independent command set; all commands are chassis-level and apply to whatever ports the card occupies. Card-specific electrical/voltage specs not present in this excerpt."
- "flow control not stated in source"
- "none applicable."
- "required spacing for firmware below 2.2.6 not stated."
- "electrical/voltage/power specs for the card not present in this excerpt. Firmware query commands do not function on analog cards (card analog/digital classification not stated for Dxci). Exact default main-port baud rate (only 'recommended 115k' stated). Flow control not specified."
