    Look at using possibly the serial pins connected to a rs485 bus. Then use ID's in your serial commands so you know what device is communicating. The appointed master simply parses out serial data...

    This is because the controller is expecting 32 universes but is seeing alot less. Mostly due to the incompatibility of the w5500 with the current one socket library (not seeing the full 16k buffer).
