ISO Programmer

This ISO Programmer was designed for home construction.  Below is a list of the items 
that make this design easier for the DIY'er.

1. There are no traces ran between component pins.
2. Because of item #1 this allows the copper pad area to be much larger, which allows a 
   bigger drill bit to be used, instead of the expensive tiny ones, without any danger 
   of the pad being destroyed. I used a #60 bit with no problems.
3. Trace widths are wider than normal. 
4. Plenty of space between traces and between traces & components.
5. The board design is single sided.  Only (2) jumpers are required.

Printing the files:

To print the Schematics, Silk Screen & PCB Layout you must first download the
WinPlot program.  This file has been uploaded along with any of my designs.
The program does not need to be installed.  Just unzip the files and WinPlot
is ready to run.  Follow the included instructions for printing each file.


Features:

The oscillator can easily be changed for programming DTV and Dish cards.

The oscillator socket can be made to support both 8 pin and 14 pin oscillators.

The smart card socket pattern will support ITT Cannon sockets:  CCM01-1NF & CCM02-1N0-32
Other venders sockets can probably be used.  You will just have to check and see.

There are two led indicators.  One indicates when power is applied and the other is
the programmer active led. This turns on when a program (ie WinExp & BasicH) is talking 
to the card.

There are four different locations the led holes can be drilled.  This allows use of 
different right angle leds if desired.  Just drill the holes for what fits best with
the leds you chose to use.


Construction Tips:

Before drilling the holes, use something with a sharp point (an awl or metal scribe
works great) to make an indent in the center of the pad.  This will keep the drill bit 
from wandering and drilling the hole off center.

Before drilling the screw holes for the DB9 connector, place the DB9 connector on the 
board and make sure the mounting holes line up with the hole is marked on the pcb.  If
they do not match mark where you want the holes to be.  Make sure the traces will not be
damaged if the holes are moved. 

Drill the DB9 mounting holes a little small and just screw the machine screw into the pcb
with no nut on the back side.  If you choose to use nuts, use a non metalic washer to keep
the nut from touching any of the traces.
