Go over the PCB again and check thoroughly for incorrectly placed components,

shorts or open circuit joints.

If all is well, turn off the power again.

Next, mount the 7406 hex open collector inverter, U4, and the ICL232 chip, U3,

taking care of chip orientation as it is very hard to remove these chips once

soldered. Remember about chip handling and static.

Now comes the time to insert the wire link LK1 near the

power jack. This can be a discarded pigtail from a

resistor or capacitor. This link completes the power

connection to the USB chip and its circuitry.

Now insert the PIC16F628 into its socket. Pin 1 is towards the power jack.

Connect a serial cable between the board and your PC. This cable is a straight

through type, NOT a null modem cable. In other words, pin 1 at one end

connects to pin 1 at the other end, pin 2 to pin 2 etc.

Make sure the switch is operated towards the [SERIAL] side.

Run the programmer software for the kit.
