At least you did not ask how to tell which one is female or male

I had that one explained to me many years ago when I was a young apprentice, funny that was one lesson I never forgot

Right then I've got:

5 - Yellow

3 - Red

2 - Brown

How does that sound / look?

Very fine wires, I was quite surprised by that.

There does not seem to be much of a standard for color coding. That is the reason to check with a meter.

Small wires. Yup. The reason I mentioned soldering heavier wires on for breadbording.

Sounds like you are about ready for some fun.

Ready and waiting

Although I haven't got my breadboard yet.

If you use a 14 pin chip in your PicKit1 the empty header holes near the diodes can be used for external to the board stuff. Solder a serial cable there??? Be sure to look at the PBP manual, gives a little schematic for serial hick ups.

Mmmm,

A little confused here mackrackit. I can see the header J3 (see attached word.docs) but can't see which of the three cables go where from looking at the diagrams.

Also, am I right in that: Pin5 = clear to send, Pin3 = receive data and Pin2 = transmit data.

Or (wild assumptions here) I can connect the three wires to anywhere on J3 as long as they correspond to three I/O pins on the socket which can be set-up to communicate with the pc COM-PORT.

As far as I know, any of the PIC® that work in the PicKit1 do not have hardware serial (UART), so it does not matter. The only exception I can think of is the ADC pins, you may want to save these for sensors, but they will still work for serial.

Pin 5
Common, ground, zero rail...
This must be connected to both devices for any serial to work.

Pin 2
Data is sent to the PC via this pin. PIC® -->> PC

Pin 3
Data is sent to the PIC® via this pin. PIC® <<-- PC

Hi mackrackit,

I'm using a PIC12F683 on my PICKit1.

I've got common pin5 on the DB9 cable (yellow) going to VSS PIC pin8.

I've got pin3 on the DB9 cable (red) going to GPIO.0 PIC pin7.

And pin2 on the DB9 cable (brown) going to GPIO.2 PIC pin5.

All via header J3.

How does that sound?
