Topic: Using HDSPe AOX-D without a switch

Hi MC!

I would like to understand how AOX-D is connected to other Dante devices or whether is possible to connect it without a switch. Here are the 2 options for what i understand:


Option A — With a switch

Cabling:

  • AOX‑D Primary → Switch
    M1620‑D Primary → Switch
    Computer’s regular NIC → Switch




Option B — No switch (daisy-chain)

Set both devices (AOX-D & M1620-D) Dante port mode to Switched (no Redundancy)

Cabling (pick one of these equivalent chains):



Using the AOX‑D as the pass‑through:

  • Computer NIC ↔ AOX‑D Port 1
    AOX‑D Port 2 ↔ M1620‑D Primary
    Leave M1620‑D Secondary unplugged



Using the M1620‑D as the pass‑through:

  • Computer NIC ↔ M1620‑D Primary
    M1620‑D Secondary ↔ AOX‑D Primary
    Leave AOX‑D second port unplugged



Example:
Diagram (AOX‑D as pass‑through)

  • Computer NIC ⇄ AOX‑D Port 1 ⇄ AOX‑D Port 2 ⇄ M1620‑D Primary


So is the option B possible? Will the Dante controller be able to control the sample rate for both devices?

Thank you! Regards Nino

From my understanding thus far, AoX-D needs to be on a switch as it doesn't pass Dante control/info through the PCIe bus.

Re: Using HDSPe AOX-D without a switch

Hi Nino,

both options are possible. The AoX has a switch chip on board and thus can be used for daisy chaining when set to "Switched" mode in Dante Controller.
