10 | How DIP switches work is unknown and you may need to turn all switches off with this converter. |
11 | |
12 | Limitations: |
13 | - Speaker/Buzzer is not supported. |
14 | - LEDs on NWP-5461 is not supported. |

24 | Protocol |
25 | -------- |
26 | NEWS keyboard protocol is a usual asynchronous serial communication. You can receive data from the keyboard easily with UART of micro controller. |
27 | |
28 | - TTL level |
29 | - 9600bps |
30 | - 1-start bit |
31 | - 8-data bit |
32 | - non-parity |
33 | - 1-stop bit. |
34 | |
35 | Its scan code is one byte consists of 1-bit release(break) flag at MSB and 7-bit code. |
36 | For example 0x29 is sent when 'a' key is pressed and 0xA9 when released. |
