eb501 to eliminate the serial cable

does any know of any information about using the eb501 to eliminate the serial cable on a homework board?
also, where can i get information about how the homework board uses rs232? i have read that it is not standard so the eb501 can not be used for programming. i'd really like/need to go wireless i also have no appmod!

any help appreciated!

    The problem with programming is that the download process requires tight timing of the serial information and the EB501 (as most other wireless links do) buffers the data into packets which alters the timing and introduces unanticipated delays. The Toothpick is the only wireless device that supports Stamp downloading. Parallax is discontinuing it (for economic reasons, not technical), but it should be available from the manufacturer.

    thanks! so i use a serial cable to program if i have to, what about just getting data out? is that possible? just to have the stamp broadcast some output? slightly off topic but can i use appmod without an appmod 'port?' can i plug in an appmod device and wire it up somehow?

    1) You can use a wireless link like the EB501 using the 5V interface to communicate with a PC to transfer data. Read the EB501 documentation. You have to establish a link with the PC using commands on the Stamp side and on the PC side. Once the link is established, the EB501 just looks like a serial port to the Stamp.

    2) Yes, you can use an AppMod without the AppMod connector. It just supplies operating voltages (Vin, Vdd, Vss) and the 16 I/O pins. You can run jumpers to connect an AppMod device to some other board. Look at the schematic for the BOE.

    One other point with the eb501-SER, it supports an EasyConnect mode of operation. This allows you to pair two of the modules and they will automaticlly connect when both are powered up. Once you have them paired, they will connect without any code on the BS2. This can be very helpful if you have a complex project and are running low on program space.

    This job would be a lot easier if I could type.
