Does anyone have a definitive answer as to what I need to hook up an E3 to a PC serial port?

The various opinions I've seen so far are:

• If you just wire it up, it may work, but you run some risk of frying the

UART in the E3.

True; I have mine wired up at present with no converter or level shifter.

• If you just wire it up, it won't work, because you need to invert

the signal levels.

• You can wire it up to an E2 line level converter and it will work.

True if taken together I believe; you need an E2 style converter plus an inverter.
