Hi all,
I'm building a sensor unit with 11 analog inputs and 1 PWM device.
At a minimum, I would like to get the 11 analog sensors hooked up to a single RS232 line. Their specs are as follows:
0-2.54V, 10mV incriments (meaning 8-bit on a 0-2.54V sensor, or 10-bit on a 0-5v).
I would like to sample them at least 10 times per second.

Are there any (inexpensive/sampleable) ADC's that I can wire the sensors to, and get an RS232 output that I can plug into the computer? I'd love to somehow get a string like this:
A055B155C254
and so on - so that I do not have to have a serial out line to ask for specific data.

Also, is there any way to make an ADC take PWM data? If not, I will be integrating several RS232 lines, so I can capture that in my microcontroller.

Thanks!
