This dedicated software driver to allows a Niagara 4 JACE controller or Supervisor to communicate directly with older American Auto-Matrix (AAM) legacy automation networks.

It enables the Niagara station to read and write data points using the legacy Public Host Protocol (PHP) proprietary format over serial connections.
Communication is typically established via physical Serial RS-232 or RS-485 ports on a JACE controller.
To use this driver, the Niagara station license must explicitly have the AAMPHP feature enabled, and the standard serial communication feature must also be present on the host.
