Installation Problem

Hi Peter,

Josh from tech support and I spent time on the phone attempting to debug the problem.
He verified (hands on) that the hardware is functioning properly.

I am using a Toshiba Satellite notebook computer running Windows XP.

I am using a USB to serial adapter (from Parallax).

We forced the serial port to COM3.

Using "Test Connection" from the Javelin IDE, the following messages are returned:

Found connected Javelin Stamp, now testing for power

Resetting

[noparse][[/noparse]Error IDE-0022] Error reading from serial port (timeout).

Windows dialog box says "Javelin not found on any port"


Thanks for any help that you can provide.

Charlie Kelly

    Have you added COM3 to the port edit list?
    Menu Project->Global options, tab debugger, click ... button
    and add com port 3 if it is not in the list.

    Hi Peter,

    Yes, Josh and I tried this.

    Since you are using a parallax usb2ser cable, have you set
    the latency timing to its minimum value (= 1) in
    the com port property setting?
    (locate the com port under device manager).

    Yes, we tried this also.

    Assuming you use a javelin demoboard, how do you
    power the board: dc adapter or 9V battery?
    The latter may give problems if the battery is
    not fresh due to required current consumption.

    I'm using a dc adapter that I purchased from Parallax

    If you have a multimeter,
    do you measure 5V at the socket headers at pins labelled Vdd?

    Also, have tried the usb2ser adapter and javelin setup on another PC?

    No, I don't have a multimeter.
    It is a 7.5 V 1.0 Amp adapter (Parallax part number: PX7510AWPL05

    Also, no I don't have another PC

    If the power LED on the board is brightly illuminated,
    you can assume the dc adapter and onboard regulator are ok.
    The javelin module itself also has a regulator
    and it outputs 5V to pin 21 (Vdd).
    If you don't have a multimeter, try connecting a LED in series with a 1k resistor
    from the socket header pin labelled Vdd to Vss (= GND).
    If the regulator is ok the led should turn on (also try to reverse the connections,
    the led should only turn on with its anode to the Vdd).
    If the led does not turn on either way, the onmodule regulator is defect.

    I'll try your suggestion.

    However, when I returned all the components to Parallax, Josh was able to use the system.

    Therefore, I suspect that it is PC/communications/software problem.

    So you had returned·the components?
    I assume you received them back so you have them now?

    Two things that you can check:
    You use the DB9 connector labelled JIDE? (do not use the one labelled COM).
    The module is correctly oriented (pin1 near the DB9 connector)?

    If both are true, you should first try to find another PC to try if
    the setup works on that.

    This is a first to hear the Parallax usb2ser cable appears not to work with
    a parallax product when connected to a laptop. Could it be your XP installation has the
    wrong driver (or·not quite compatible)·installed for your laptop's usb port?

    Hi Peter,

    the DB9 is connected to port labeled JIDE (I left my configuration in tact when I returned the components to Parallax).

    Josh and I re-installed the drivers while he was providing telephone support.

    Thanks for your help.

    Also, do you have access to another PC to try and narrow it down to a communication with that PC? Do you have any Palm Pilot/PDA software such as Active-Sync or Hot-Sync?

    I have the same communication issue with my Javelin Demo board.· I tried all the previous suggestions and found on this forum.··Found that·the problem·was actually the USBtoSerial Cable and/or driver.· On my desktop I found a serial connector and plugged in the straightthrough cable.· Loaded the program and it worked!
