BASIC Stamp Programming Connections
We suggest using a Parallax development board and cable for
programming BASIC Stamp modules. When these items are not available,
you may create your own board by duplicating the following diagrams
with your own circuits and cables.
Be very careful to follow these diagrams closely; it is quite common for
programming problems with the BASIC Stamp to be a result of a poorly
made custom cable or programming connections on your applications
board. With the programming connections for all the BS2 models, it is
possible to reverse a couple of wires and still get positive results using
some of the "connection" tests our Tech. Support team tries and yet you
still will not be able to communicate with the BASIC Stamp. It is vital that
you check your connections with a meter and verify the pin numbering to
avoid problems like this.

Note: Though it is not shown, power
must be connected to the BS1 to
program it.
