WARNING

Be aware that the chips used in your kit are sensitive to static electricity discharge and could be damaged by mishandling of the PCB. Be careful with the board and avoid touching any of the tracks or pads while assembling it. Try to handle it only by the edges.

VERY IMPORTANT

Please do not insert any chip into the programming socket unless the board is connected to the PC either via the serial port or the USB port and the MicroPro software is running.

The controller PICmicro® on the board is held in a reset state until MicroPro gains control of it. In this reset condition, there will be stray voltages present in the programming socket.

There is a modification that keeps these voltages turned off unless needed by the programmer. Please see “resmod.pdf” in your installation directory. Later version kits have this modification already installed.

Even will this modification, it is not advisable to turn the programmer board off and on while a chip is in the programming socket.

Clk & Dat Programming Pins

On the programmer board, the PICmicro® driver chip has the Clk and Dat pins set as inputs when the programmer is idle. These are set as outputs only when programming takes place.
