diagnostic data, and for communication with other subscribers.
The PMI 509 has additional buttons which can be used to control special functions within
an application.
The device is fitted with a real­time clock that is battery­buffered, so allowing it to run for 90
days without an external power supply. The battery is automatically charged during normal
operation by the power supply for the device.
