+
+This converter allows NEWS keyboard to be connected to modern PC via USB. It works with NWP-5461 and NWP-411A.
+
+How DIP switches work is unknown and you may need to turn all switches off with this converter.
+
+Limitations:
+- Speaker/Buzzer is not supported.
+- LEDs on NWP-5461 is not supported.

+Protocol
+--------
+NEWS keyboard protocol is a usual asynchronous serial communication. You can receive data from the keyboard easily with UART of micro controller.
+
+- TTL level
+- 9600bps
+- 1-start bit
+- 8-data bit
+- non-parity
+- 1-stop bit.
+
+Its scan code is one byte consists of 1-bit release(break) flag at MSB and 7-bit code.
+For example 0x29 is sent when 'a' key is pressed and 0xA9 when released.
+
+ MSB LSB
+ 7 6 5 4 3 2 1 0 bit
