INTRODUCTION

    This is a production release of firmware for Digi's ConnectPort X2
    Wireless M-Bus Gateway.
    
    The ConnectPort X2 with Wireless M-Bus provides a secure, reliable
    connection that adds monitoring capabilities between a Home Area Network
    (HAN) and an energy service provider’s management infrastructure. The
    gateway incorporates the Wireless M-Bus standard (EN13757-4:2005), which
    defines the communications protocol between devices such as water, gas,
    heat and electricity meters, in-home displays and concentrators. The
    ConnectPort X2 with Wireless M-Bus enables energy service providers to
    deploy HAN devices such as in-home displays, ideal for today’s smart grid
    initiatives.
    
    The M-Bus Gateway is intended to allow wireless M-Bus-enabled water, gas,
    and electric meters to connect to iDigi via Ethernet or to a Smart Energy
    network. This allows legacy M-Bus meters to be brought into the emerging
    Smart Energy infrastructure and to make meter information available for
    collection and distribution via iDigi. 

    The M-Bus Gateway will be a boxed product with enclosure and preprogrammed
    firmware. The device will fit within the existing ConnectPort X2 enclosure.
    The M-Bus Gateway will include a ConnectME 9210 and will connect M-Bus
    devices directly to iDigi. 

    These devices will be used within homes to connect M-Bus devices to the
    iDigi framework and/or a Smart Energy network. This will allow connecting
    customers meter information to be made available via an information portal,
    thus empowering customers to change usage habits based on their past
    consumption.

ENHANCEMENTS

    The factory default sequence (holding the reset button while powering up
    the X2) is now used to initiate the factory default of the Amber module
    The result can be seen in the event logging.
    
    The Amber module now receives a hardware reset on startup.
    
    The Amber module now has it's preselect set to T2-Other in the EOL test
    to make sure it can properly receive meter requests.

    The CPU clock frequency has been set to 128 MHZ instead of 150 MHZ to
    pass emissions testing.
