Is this possible? Can't seem to connect (Tools..Preferences..Find Processor) to the Basic Atom Pro 24 using Basic Micro Studio and a Board of Education with an FTDI USB -> Serial converter? Or is this not possible?

Any help would be appreciated.

The USB-Serial cable must have more than just serial-recieve and serial-transmit lines on it. Most cheapo PDA-suitable cables are like this. The Pro24 module must get a reset pulse to get the bootloading code's attention, and this is done with a third signal line. If not, you will never "see" the module using "Find Processor". Try to find the spec sheet for your cable and see if it supports serial signals other than the two mentioned.
Take care.

You can use SOME parallax boards. We've found that the new USB based parallax boards will not work. They use a slow inverter on each pin fromt eh FTDI instead of usign the FTDIs invertering option which doesn't allow the 115kbps communications needed to program our modules. Older DB-9 based Parallax boards can work. Most of them however need you to bypass a cap that is inline with the ATN pin. If you really want to use the FTDI based Parallax board you would need to bypass the external inverter circuit on TX,RX and RTS, and reprogram the FTDI using FTDIs MProg program so those pins are inverted. We haven't gotten as far as bypassing the inverter circuits but we do plan on testing it soon. By bypassing the circuit and inverting the pins using MProg you will end up with a board that works the same as our own USB Devboards.
