I'm having a problem communicating with my BS2 using the windows
editor. It can identify the Stamp is there but says to check power
supply. I have scoped and probed all voltages possible according to
the schematic and they appear to be there. I get a -5V reading on the
Sout pin. Is this correct? If I understand the manual correctly the
voltage should switch between -12V and +5V.

probably haven't gone to the extent you have, but you are receiving the same
message as me. I have been corresponding with parallax for a week about
this, but have not come to any conclusions. I will post the solution when I
get it.

that would imply that your PC (a laptop maybe) is sending -5 instead of -12.
That shouldn't be a problem, since if the PC is generating -5 it should
expect -5.
A few things to think about.
1) Do you have either 5V connected to +5V (pin 22 If I recall) or 9V or more
connected to pin 24?
2) Do you have the ground pin grounded with a common ground to the power
supply and the computer (pin 5 of the DB9).
3) Do you have pins 6 & 7 shorted together? The Stamp editor uses this to
find the Stamp.
4) Is it possible you are using a "cross" cable that is reversing pins 2 and
3?
A few more questions:
a) What are you using? A BOE, a carrier board, an ASP-2, or something
homebrew?
b) What operating system?
c) What Stamp software (DOS, Windows, version?)
d) Are you using a BS2 or a BS2SX?

BS2 on a BOE in win98. I bought 3 at the time and 2 work, one doesn't.
Although it did appear to work for about 5 uploads. Don't ask me how, but
when it quit, it took out my comm port. I had to reinstall the hardware to
get it back. This has happened twice now. I don't seem to have any
problems with the DOS version of the editor.

Offhand I can tell you that the cable is a straight thru. I
understand
the basic concepts of RS-232 comms. I checked the voltages on the
actual cable itself and found my PC (running Win95) is putting out
-10V on the ATN and SIN lines but I get nothing on the pin that is
connected to SOUT until I attach it to the BS2 carrier board, which I
am using, and that's when I get the -5V. At the base of the PNP
transistor I am getting +5V from the micro-controller which I believe
is the PIC's TX line. Right now I am using the Windows editor. The
mystery to me is that all was running well last time I used it, now I
cannot even run the last program I entered after I hit the reset
button. I'm beginning to fear the worst! As for your other points I
will have to check them out later. Thanks again.

possible to control a video signal through the bs2? Something like turning
on and off or switching from one source to another or adding noise or
something like that.

This is the first time I've responded to a question, so bear with me.

I joined this group to learn about the BS2 because I was building a 16
channel surveillance camera switcher using the BS2, NCD's ASEL video
switcher, a Scott Edwards VFD module and a Decade Engineering BOB 2 On
Screen Display module. The BS2 controls all the major modules (listed above)
via serial control. The NCD crosspoint module is a little elaborate, and not
really all that appropriate for video (I know, I'm a professional video post
production engineer) but it's works just fine for this application. It would
have been cheaper to use MAXIM crosspoint chips and a little associated
cicutry. But the NCD modules were all built and ready to go, and had the
serial interface built in, so I went with those.
The project is basically finished now. If you would like further information
on the project, let me know.

tell that a BS2 was there, but it couldn't communicate and to check
the power supply. i contacted Parallax and, while they gave me
several things to try, none of their suggestions fixed it. i was
getting worried that i had shorted the chip or something when i
realized that i was using an extention of .bs2 when i had a BS2sx.
changing the extention to .bsx made all the difference in the world.
hope this helps.
