NEWS protocol is a usual asynchronous serial communication. You can receive data from the keyboard easily with UART of micro controller.
-
TTL level
-
9600bps(keyboard) / 1200bps(mouse)
-
1-start bit
-
8-data bit
-
non-parity
-
1-stop bit.
Data is received as serial input at 9600 bps from the keyboard and 1200 bps from the mouse.

sBF3-7-2. keyboard Buzzer
The NEWS series keyboard features a built-in buzzer which can be buzzed by a signal from the system unit. In the NWS-1500, the external oscillator circuit is activated when the keyboard buzzer port is accessed, producing the sound of a buzzer. The buzzer frequency is different depending on whether the port is read or write accessed. With READ, the tone produced is approximately 2.2kHz, with WRITE, approximately l.4kHz. A flowchart of this process is given below.
Buzzer can be drived with pulsing on BZ pin.
With TMK firmware you can use tone() functrion to control the buzzer.
