Re: Using an Operator Interface with the 2004 EDU RC wirelessly

The reasons that you can't plug the 2003 modem into a 2004 EDU are

1. It doesn't have a modem port.
You could create an external box that converted the serial signal of the modem to the inputs on the EDU. This would require a relatively simple microprocessor circuit.

2. You can't plug it into the serial port because the voltage levels are incompatible.
You could create an external box to shift the level of the modem signal, then plug into the serial port, and write some interface code to process the signal.

While both workarounds are good challenges, Dave's solution was designed to be a quick, low cost for teams that have a 2003 EDU, but do not have the resources to design the necessary interface circuitry.

I would imagine that at this stage in the game that most teams would be more interested in exploring how to write functioning C code than creating interface modules.

EDIT: Dave beat me to the punch in replying, sorry for the duplication
