Kid Serial Data Wiring

[felix]

Hello, I read that the Kid can output serial data that can be read by a device such as a raspberry pi. Does any one know how to get the KID to output the data and how the wiring would look like to read that data from a PI? Firmware on the kid is 18.11 I appreciate any help. Thanks.

Hardware:
You need to connect to the KID using rs232. Google Pi and rs232 and there are many examples of wiring an rs232 shield or building an interface using a MAX3232 ic.
You need to make a cable with DB9 female to connect to shield and at other end an RJ11 connector to plug into the KID serial port (not the USB socket)
Only 3 wires are used, Earth, Send and Receive, pins 5, 2 and 3 on DB9 and pins 4, 2 and 3 on RJ11
The Send on DB9 needs connected to Receive on RJ11
The Receive on DB9 connects to Send on RJ11
Earth DB9 to Earth RJ11
Software:
You need to write code to extract data from the KID
Search for details in this forum as info on what to do has been posted before

Here is the PinOut:

DB9                        RJ11 ( Master jack in Kid CC)
5_GND          -------- 5_GND
2_RXD-IN      -------- 3_TX-OUT
3_TXD-OUT   -------- 4_RX-IN
