The release notes for firmware 3.13 released on May 5th mentions an email notifier board. I haven't been able to find any more information on when it will be available or how much it will cost.
- Added Support for E-Mail Board. The new E-Mail board may be configured from within PC Access 3. In order to use this feature you must have a network capable controller with firmware version 3.13 or higher. You must also have at least one serial port configured for the E-Mail board protocol.
