Terminal Software

Before your KM7 can do anything useful, you need to Switch it ON.

Switching ON your KM7

KeyMaker 7 USB

Plug 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.

You turn ON your KM7 by sliding the power Switch to the right as per the image above.

You should the see the Green Power LED light up and stay ON.

You should see a few quick flashes of the Red TX and RX LEDs

Your KM7 is switched ON and ready to go.

To Switch your KM7 OFF slide the Power Switch to the LEFT and the Green Power LED will turn off.

 There are a lot of different Terminal Software programs out there, most are free.

Windows comes with a Terminal Program called Hyperlink which you can access by Start - All Programs - Accessories - Communications - Hyper Terminal.

The choice is yours,  almost any Terminal Software should work with KeyMaker 7 (KM7)

I prefer to use a program called Tera Term which is available for Download here  tera term save the downloaded file to your computer then run the exe file just like any other Windows program to Install it.

If you run another operating system then you will need to search the net for a suitable Terminal Software program for your Operating System.

The following is about Tera Term running under Windows however you can use this as a guide for most Terminal Software.

The USB interface on KM7 and the FTDI Drivers act as a USB Serial COM Port to which Windows assigns a COM Port Number.

This is a good time to be introduced to the switches and button on your KM7

Let's start with those 3 slider switches on the left side.

  1. Top 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.

  2. The 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.

  3. The bottom Switch is the Power Switch, OFF to the Left, ON to the Right.

Down the bottom left, you have the RESET Button, which we will be using further down this page

On the right, the 4 wire cable has been plugged in over the I2C Header pins, NOTE: the RED wire goes over the VCC pin.

I should mention at this point that it is better to turn ON KM7 before you run your Terminal Software.

The 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.

So 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;

COM PORT: 
Baud rate: 115200
Data: 8 bit
Parity: none
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

You should see KM7's Initial Product Activation Screen, the background and Text colours will vary depending on your settings.

Don't concern yourself with Activation right now that is fully covered later, for now lets get KM7 to display something.

If nothing appears on your screen.

Watch the KM7 board while pressing and releasing KM7's RESET button which is next to the illuminated GREEN Power LED.

Each 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.

If 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.

The usual cause for not seeing anything on the screen is you have selected a valid COM Port but the correct COM Port for KM7t.

Finding the COM Port KM7 is attached to

The easiest way to find out which COM port KM7 is on is to

Click on START, Right Click My Computer - Properties

The System Properties window should appear.

Select the Hardware tab by clicking on it, then click on Device Manager

In the Device Manager Window, scroll down until you see Ports (COM & LPT)

Click on the + symbol on the left of that line + Ports (COM & LPT)

Which call cause it to Expand and display all available Ports.

Watch that list while you switch KM7 OFF for a few seconds then switch KM7 back on again.

The 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.

Now you know for sure what is the correct COM Port, go back to your terminal Software and select that COM Port.

On my PC, when KM7 is switched ON, USB Serial Port (COM21) is displayed

.

When KM7 is switched OFF, USB Serial Port (COM21) disappears, so my KM7 is attached to COM Port 21

Setting Tera Term colours for background and text can be customized by clicking Setup - Window..

To set Text colour, click the Text Radio Button and move the R G B Sliders, then click OK

To set Background colour, click the Background Radio Button and move the R G B Sliders, then Click OK

Now that you can interact with Km7 by using a Terminal Program it is time to deal with Activation
