1.4.2 Electrical Connections
Figure 1-2 shows how the Signal Analysis PICtail Daughter Board plugs into the
PICkit 1 Flash Starter Kit expansion header J3. The Signal Analysis Board electrically
detaches the PICkit 1 onboard LED array. The target PICmicro device is plugged into
the Signal Analysis Board DIP socket U1. Remove any PICmicro devices from the
Evaluation Socket on the PICkit 1 Flash Starter Kit.

ORIENTATION
Figure 1-3 shows the electrical connections of the Signal Analysis PICtail Daughter
Board with the PICkit 1 Flash Starter Kit. There are five connections: +5V, Ground,
ICSPCLK, ICSPDAT and V
PP (see Figure A-1 in Appendix A. “Hardware
Schematics”). These signals allow the target PICmicro device, plugged into U1 DIP
socket on the Signal Analysis PICtail Daughter Board, to be programmed and provide
bidirectional synchronous serial communications with the PICkit 1 PIC16C745 micro-
controller with USB device. With PICkit 1 V2.0.0 (or later) firmware, the user can
communicate to and from the target PICmicro device via USB serial communications.
This facilitates PC host programs to command, control and communicate with the
target PICmicro device that is being evaluated or for program development.
Note: When the Signal Analysis PICtail Daughter Board is plugged into the
PICkit 1 Flash Starter Kit, remove any PICmicro devices from the Evalua-
tion Socket on the PICkit 1. The target PICmicro device used for evaluation
and development is plugged into the DIP socket U1 on the Signal Analysis
Daughter Board.
