    Gents, a partner and I are doing a studio install centered on a SQ5 and 2x DX1608 in a multi-room environment.

    we plan on wiring every room with redundant CAT6 cabling terminating in the control room to the SQ-Link port.
    Since the 2nd DX box has to be run in series to the 1st and considering that the main room may need more then 16 i/o’s, what is the way to run a RJ45 type “patchbay” allowing us to route signal to and from all the rooms? Would a gigabit switch be the ticket?
    Many thanks,

    Would a gigabit switch be the ticket?

    I’m afraid no and of course, it depends… 😉

    What is your goal? Maybe a DX Hub could help…

    Hi, the goal s to route the SQ-Link protocol to the switch so that all the rooms RJ45 terminating at the switch can be patched in and out according to will. Makes sense? Possible? Txs.

    Hi @lozion

    The A&H protocols that the SLink port can switch between are all intended for direct connection and are not IP based (like Dante for example), meaning it is not possible to create a ‘star’ configuration of units using a switch.
    You can connect/cascade a maximum of two expanders to DX or dSnake ports (as found on Qu/GLD/dLive), and this is also the case when an SLink port is running in either of these modes.
    The GigaACE/GX protocol is slightly different as it can be used for direct connection and there are a couple of exceptions with expansion:
    The DX-Hub – ‘translates’ between the 128×128 96kHz Gigabit GigaACE protocol and the 32×32 96kHz Fast Ethernet DX protocol.
    The GX4816 – which is like having an expander with local I/O that also includes the last two ports of a DX-Hub built-in (and the second of these is intelligent and can be used with DX or a ME system!)

    When connecting directly to an SLink port, the port detects the speed of the connection then discovers expanders to know which mode to be in.
    If it detects a gigabit speed (which could be from GigaACE, but also from connection to a gigabit switch) then it will switch to GigaACE.
    If instead, it detects 10/100 fast ethernet, then it will switch to DX if it discovers a DX unit, or dSnake if it discovers a dSnake unit OR nothing (which would be a ME unit).

    So it is possible to use a switch in-between the SLink port and an expander, but it has to be running at the correct speed for the protocol you are using and there can only be one expander connected directly to that switch.
    There’s other things to consider if you use a managed switch.

    For the situation you describe, in theory you could use [ multiple rooms <> 10/100 unmanaged switch <> SLink port ] and make sure you only connect the DX units in one place at a time and have nothing else on that network.

    But we’d recommend a direct connection… or Dante.

    Sounds like a fun project!


    PS – I realise you know most of this, but I’ve expanded (pun intended) for completeness.

    Right. Time to apply the good Ole axiom, “if it can go South, it will..”
    Txs Keith.
