I've seen a Martin Logan MDA-16 amp that looks ideal for my needs :

    That brain is not that inexpensive

    No scripting necessary. Big 5 is made for non programmers.

    Since scripting is going to be needed to facilitate the use case then what advantage does Big5 add? This seems like straightforward serial communication to me using the .NET serial library. If Big5 added the bidirectional communication between the amp and HS without events and without scripting then this would be a value added.

    The answer is YES as far as Big5 is concerned. I'm using Big5 to control several legacy systems and it works reliably. I'm using both USB to serial cable/converter for the systems that are in the same room as HS3 and IP to Serial servers from "Helo Devices" f.k.a. Sena for the systems that are in a remote to HS3 location. Both technologies work great.

    Hi there!

    "The RS-232 connection allows connection to a compatible control system. The control system should be configured to use 115200/8-N-1, no flow control, protocol. The cable connection should be one to one."

    It then goes on to provide a full table of serial commands, such as:
    ZxPOWy Set zone x power.
    x=zone: 0 (all), 1=zone 1 ../. 8=zone 8
    to y:
    0=off
    1=on
    t=toggle.
    When unit is in 1/2W standby mode, it may be necessary to send the power-on command twice. Ex:"Z0POW1;Z0POW1;". The first instance is the wake-up from low-power state. Note that Zx=Z0 applies only to power command.
    ZxPOW? returns ZxPOWy

    Z0POW? returns ZxPOWy for all zones (Z1POWy;Z2POWy;Z3PO…;Z8POWy
    Before I purchase, can I confirm that I will definitely be able to control using HS3 + Big5?

    Is it as simple as buying a usb to serial cable and scripting the commands I need to use?

    Thanks in advance for your help!
