Terminal Software

Before your KM8 can do anything useful, you need to Switch it ON.

Switching ON your KM9A

KeyMaker 9A USB

There are 2 versions of the KM9AUSB board - the one above and this one, functionality for use on ThinkPads is identical.

Plug in your Mini USB cable into your KM9USBZ 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 KM9 by sliding the power Switch to the right as per the first image above or by plugging in the USB connector on the board above which does NOT have a power switch..

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 KM9AUSB is switched ON and ready to go.

To Switch your KM9AUSB OFF slide the Power Switch to the LEFT or unplug the USB connector 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 9A (KM9A)

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 KM9A 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 buttons on your KM9A

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

  1. Top one is not used by KM9A 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 either 5V or 3.3V, leave it on 3.3V switched over to the LEFT.

  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.

On the top left you also have the ZAP SVP button.

The other version of the KM9A board

Let's start with those 2 slider switches on the left side.

  1. Top one is not used by KM9A 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 either 5V or 3.3V, leave it on 3.3V switched over to the LEFT.

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.

On the top left you also have the ZAP SVP button.

NOTE: This version of the KM9A board does not have an ON/OFF switch, it is switched ON and OFF by plugging in or disconnecting the USB cable.

I should mention at this point that it is better to turn ON KM9A before you run your Terminal Software.

The reason being that until KM9A 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 KM9A ON first, then run your Terminal Software.

Select the COM Port that was allocated to KM9 during the USB Driver installation.

If you are not sure which COM Port KM9A 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
Tansmit delay: 1 msec/char 5 msec/line

 

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 KM9A, Bottom left of board brass coloured push button labelled RESET.

You should see KM9A'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 KM9A to display something.

If nothing appears on your screen.

Watch the KM9A board while pressing and releasing KM9A'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 KM9 board flash very briefly, that is the TX LED which flashes any time serial data is being sent out by KM9A 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 KM9A.

Finding the COM Port KM9 is attached to

The easiest way to find out which COM port KM9A 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 KM9A OFF for a few seconds then switch KM9A back on again.

The COM port that disappears each time you turn off KM9 and re-appears when you switch KM9A back on again is the COM Port assigned to KM9A 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 KM9A is switched ON, USB Serial Port (COM21) is displayed

.

When KM9A is switched OFF, USB Serial Port (COM21) disappears, so my KM9A is attached to COM Port 21

NOTE: In the images displayed below, THE BACKGROUND is NOT from a KM9A, ignore the background.

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 KM9A by using a Terminal Program it is time to deal with Activation
