Editor doesn't find the Stamp

OK, this is my first try, my first program to download to the Stamp...running PBasic 2.5, Win 98, BS2. I input a canned program, selected RUN and am told that "No Basic Stamp was found." I have doubled checked the wiring, checked for voltages to be where they should, checked for continuity in the cable. I need suggestions for things to check. Do I have to do anything special with the computer so it uses the serial port properly...what port settings, e.g.? This is all pretty new to me.

    Hello,

    You may have to turn off the FIFO buffers.· Here is a simple way of doing this:

    1.· Go to your Control Panel.

    2.· Click on Systems.

    3.· Click on Hardware Settings.

    4.· Click on Device Manager.

    5.· Scroll down to Ports.

    6.· Double click on the Com Port that you are using.

    7.· Click on the Port Setting tab.

    8.· Click on the Advanced button.

    9.· Uncheck the FIFO box.

    10. Click on Okay on the way out.

    Dave

    Thanks, Dave.· I tried that...unchecked FIFO...still no luck.
    Here's some additional info:

    When I do a RUN ---> Identify, for COM 1 (which I believe is the port I'm using) I get:
    · Loopback = Yes
    · Echo = Yes.
    · Device Type = (nothing)

    Does this say anything useful here?

    That's what you see if your BS2 is un-powered.

    Yes the Stamp's power must be on. Been there, done that.

    I am having the same problem (still) trying to run my Stamp from my old DOS computer.
    I like to use the old computer because it's there.

    Everything works on my WIN98 machine: same program, cable etc.
    I can connect and run both in WIN98 and from a DOS window running under WIN98

    But no luck on the old machine and the power is on.

    I've got exactly the same problem as Iac.

    BS2 (industrial version)

    9V to pin 24, GND to 23
    Measure 4.99 @ pin 22

    RX (DB9-2) to pin 1
    TX (DB9-3) to pin 2
    DTR (DB9-4) to pin 3
    GND (DB9-5) to pin 4

    I have LEDs thru 1K from both SIN and SOUT to GND.

    When I try to identify (Ctrl-I) the stamp, there is activity on both SIN and SOUT: 5 brief pulses. Result: Loopback-YES Echo-YES
    If the stamp is powered off, I see 5 brief pulses on SIN, nothing on SOUT (of course). Result: Loopback-YES Echo-YES

    If the stamp is powered on, but I disconnect SOUT from the DB9, I see one pulse on both SIN and SOUT, Loopback-YES, Echo-NO
    Power off, SOUT disconnected yields one pulse on SIN, Loopback-YES, Echo-NO

    I'm at a loss. Can you help?

    Thanks.

    Oh, yeah- I also tried it with the LEDs out, so it's not that they are loading it down.

    And one more thing (I think!).

    Running XP Pro, Belkin F5109U USB-serial adapter as COM7, 9600-N-8-1, no flow control, FIFO disabled (also tried with FIFO enabled, no luck).

    That's it, I promise!

    This looks like two different problems, the Belkin adapter is not known to work with the BASIC Stamps.· There are two known adapters that will work with the BASIC Stamp and they are the Key-Span model # 19HS and the FTDI adapter that we sell.· Here is a link for more information regarding the FTDI adapter:

    Regarding lac's issue:·· Make sure that you are running the latest editor version 2.1.· You mentioned that you are using a canned program, make sure that there isn't a com port directive in your code already.· If this doesn't work, please give the Parallax tech support a call at 1-888-997-8267.

    Dave,

    Thanks for the help- I tried on a desktop with built-in serial port; it worked like a champ <sheepish grin>. I actually remember now reading about the USB-serial converter issue, just kinda forgot about it.

    Thanks again,

    Steve
