your KM7 can do anything useful, you need to Switch it ON.
ON your KM7
in your Mini USB cable into your KMs and plug the other end of your USB
cable into the USB port of a PC or Laptop that is Switched ON.
turn ON your KM7 by sliding the power Switch to the right as per the
should the see the Green Power LED light up and stay ON.
should see a few quick flashes of the Red TX and RX LEDs
KM7 is switched ON and ready to go.
Switch your KM7 OFF slide the Power Switch to the LEFT and the Green
Power LED will turn off.
are a lot of different Terminal Software programs out there, most are
comes with a Terminal Program called Hyperlink which you can access by
Start - All Programs - Accessories - Communications - Hyper Terminal.
choice is yours, almost any Terminal Software should work with
KeyMaker 7 (KM7)
prefer to use a program called Tera Term which is available for Download
term save the downloaded file to your computer then run the exe
file just like any other Windows program to Install it.
you run another operating system then you will need to search the net for
a suitable Terminal Software program for your Operating System.
following is about Tera Term running under Windows however you can use
this as a guide for most Terminal Software.
USB interface on KM7 and the FTDI Drivers act as a USB Serial COM
Port to which Windows assigns a COM Port Number.
is a good time to be introduced to the switches and button on your KM7
start with those 3 slider switches on the left side.
one is not used by KM7 Firmware, it is used when the board functions
as an Arduino board for Boot Loading, best left switched over to the left
as in the image above.
middle one, switches VCC to the ATmega328 and the VCC pin on the
EEPROM connector, leave it on 3V3, switched over to the left unlike
the image above which shows it in the 5V position.
bottom Switch is the Power Switch, OFF to the Left, ON to the Right.
the bottom left, you have the RESET Button, which we will be using further
down this page
the right, the 4 wire cable has been plugged in over the I2C Header pins,
NOTE: the RED wire goes over the VCC pin.
should mention at this point that it is better to turn ON KM7 before you
run your Terminal Software.
reason being that until KM7 is turned on its COM Port doesn't exist,
so your Terminal Program would not find it which can be frustrating if
you don't realize what's happening.
turn KM7 ON first, then run your Terminal Software.
Select the COM Port that was allocated to KM7 during the USB Driver installation.
If you are not sure which COM Port KM7 is attached to,
see further down this page for help in finding the right COM Port
Set up the Serial Port on your Terminal software to;
Baud rate: 115200
Data: 8 bit
Stop: 1 bit
Flow control: none
Save all these setting so you don't have to do this again.
On some Terminal programs you also need to CONNECT
before anything useful happens.
The drop down screen for making these settings in Tera
term is shown below
You get there by - Setup - Serial port..
Each of the settings has a drop down menu which allows
you to chose the correct settings, click OK when done.
To save those settings, you would chose - Setup - Save
setup - type in a name and click Ok, now each time Tera term is run it
starts up with all the correct settings.
Press the Reset button on KM7 - see the KM7 photo
further up this page for RESET Button location
should see KM7's Initial Product Activation Screen, the background and
Text colours will vary depending on your settings.
concern yourself with Activation right now that is fully covered later,
for now lets get KM7 to display something.
nothing appears on your screen.
the KM7 board while pressing and releasing KM7's RESET button which is
next to the illuminated GREEN Power LED.
time you press and release the reset button you should see a RED LED on
middle of the KM7 board flash very briefly, that is the TX LED which
flashes any time serial data is being sent out by KM7 to your computer
via the USB Port.
the RED LED flashes it confirms all is well as your board is indeed
sending out the Initial Activation Screen to your computer but you are
not seeing it.
usual cause for not seeing anything on the screen is you have selected a
valid COM Port but the correct COM Port for KM7t.
the COM Port KM7 is attached to
easiest way to find out which COM port KM7 is on is to
on START, Right Click My Computer - Properties
System Properties window should appear.
the Hardware tab by clicking on it, then click on Device Manager
the Device Manager Window, scroll down until you see Ports (COM &
on the + symbol on the left of that line + Ports (COM & LPT)
call cause it to Expand and display all available Ports.
that list while you switch KM7 OFF for a few seconds then switch KM7
back on again.
COM port that disappears each time you turn off KM7 and re-appears when
you switch KM7 back on again is the COM Port assigned to KM7 by Windows
and the FTDI Drivers.
you know for sure what is the correct COM Port, go back to your terminal
Software and select that COM Port.
my PC, when KM7 is switched ON, USB Serial Port (COM21) is displayed
KM7 is switched OFF, USB Serial Port (COM21) disappears, so my KM7 is attached
to COM Port 21
Tera Term colours for background and text can be customized by clicking
Setup - Window..
set Text colour, click the Text Radio Button and move the R G B Sliders,
then click OK
set Background colour, click the Background Radio Button and move the R G
B Sliders, then Click OK
that you can interact with Km7 by using a Terminal Program it is time to deal
