Click [File] -> Port or double click the COM x label on screen to bring up

the COM port window. Select the COM port that you will use for serial

communications, then [OK].

Re-check the power and PC connections and turn on the programmer board.

You should see Board connected appear on screen. If not, check your cable,

the PC port setting and also that the switch is set properly.

If all is well, then as a simple system test, select 16F84 from the chip select

menu and click on Read. You should see some LEDs light and the programmer

will read from a non existant chip. The screen will most likely fill with 0000's.

Now you can turn off the PCB and prepare it for the USB test.

First off, disconnect the serial cable and move all of the switch to the [USB] side.

To enable USB capability for your PC and this project you will need to install a

special driver. This is a piece of software that handles the communications

between the PC and the special USB chip on the programmer PCB.

Create a USB driver sub directory into the directory where your programmer

software was installed. C:\diyk149 was the default. Therefore you would have

a new directory called C:\diyk149\usb.

The drivers come in 2 flavours, plug and play support and no plug and play

support. As this programmer does not have plug and play support, that narrows it

down to 1 choice.

You will need to visit this web page and download this driver.
