problem with serial and javelin stamp

I recently ordered a javelin stamp to go with my boebot's BOE. The program is failing to program the javelin with the error code [noparse][[/noparse]IDE – 0056]. I'm using a serial adapter manufactured by airlink101 based on a prolific usb to rs232 chip. I don't know what is wrong.

The board i have is a serial BOE rev B, i tried the resistor fix thing, but it didn't help.

Thanks in advance for helping me.

    I have a prolific chip (PL-2303) based usb/serial cable that didn't
    work either with the supplied usb drivers.
    Once I installed the prolific originals (I have windows XP):
    http://www.prolific.com.tw/eng/Download-2.asp?ID=17

    it did work. It may work for your cable too.
    Also make sure any latency setting is set to minimum
    (if the usb driver provides such a setting).

    i'm running vista, and the only drivers that work are the supplied ones.

    and suggestions since the ones on prolific's site are for xp and lower only, not vista

    Parallax has a converter that does work with Vista:

    BTW, have you added the com port to the port list?
    In Javelin IDE go to Project -> Global options
    Select tab debugger.
    Click ... button
    Now you can add the port number if not in the list.

    ok, i checked the com port, and it is there.

    I tried another computer running xp with a built in serial port on the MB, and i get the same error.
    Could it be that my javelin stamp is deffective?

    Also what is the resistor fix for?

    The resistor fix is for USB boards. The resistor ensures the sx48 rx pin
    is pulled low sufficiently. For serial boards the resistor is not necessary
    but it doesn't hurt either.

    On the xp machine, is there any software running that may
    interfere with serial ports, like Hot Sync or a simular program?

    Measure the voltage on the javelin module pin 21 (VDD).
    It should be 5V when the module is powered.
    If it is not, the module's onboard regulator is defect.

    Is that using the usb cable? If so, the serial port timeout
    is probably due to the latency setting of the usb driver.
    You need to set the latency to minimum (I hope the driver
    allows you to set the latency).

    ??, ok i found out there is no latency setting for me, and i'd get the timeout error, but now i get error ide 0052, incompatible firmware revision ($f)

    what does that mean, and how can i fix it?
