The snom PA1 is equipped with a 8 pin keyboard connector, to be able to use the keyboard matrix.
The keyboard matrix can be used to control the snom PA1 button events, like you do it with all other snom phones. For example, you can use the programmable keys to initiate a call to an extension.
As an example on how to use the keyboard matrix, we created a Keyboard Extension pcb.
This Keyboard Extension pcb will not be sold by snom as a product. Yet we provide a complete set of design data for the pcb. You can order this pcb with this data from a PCB manufacturing service.
