To connect the Velleman VM134/K8076 PIC Programmer Board to your PC, follow these steps:
1. Make sure there is no controller in the ZIF socket.
2. Connect the serial connector of the programmer to a free serial RS232 port on your PC. The serial port must be 100% IBM compatible and 16550 UART compatible.
3. Connect a 15VDC power supply to the programmer. This voltage may or may not be regulated since the PCB is equipped with a voltage regulator. A 12VDC non-regulated adapter will work, as the terminal voltage is about 15 to 16V.
4. When you switch on the power supply, the LD1 or "Power Good" LED will light up. This indicates that the programmer is live and that the controller is provided with +5V.
5. Start the "PICprog2006" software and click on the icon on the upper right corner, labeled "Hardware connections".
6. By clicking on the LD3, LD2, and LD4 LEDs with your mouse, they should light up on the PCB.
7. Press "Run hardware datelines test" to start an automatic LED lighting sequence. These LEDs must light up synchronously with the screen. Press the button again to stop the testing procedure. Note: Make sure there is no PIC in the socket during this test.
8. If the test went well, you are ready to use the programmer. If not, check for any hardware errors on the board or incompatibility with your PC to avoid damaging the PIC controllers.
