Maybe Zoomkat should post a schematic.

I wouldn't mind seeing that too. What code changes would need to go along with a multiplexer? Would the firmware need to be updated?

You can easily mark up your own schematic if desired. I've been working with the CD74HC4051, but the below CD74HC4067 will give 16 inputs so is probably a better choise to work with. Look at the pinouts on the below data sheet. The VCC connects to the +5v on the ssc-32, the ground and E bar connects to the ssc-32 ground. The common input/output connects to an analog input pin on the ssc-32. The S0-S3 connect to four servo control signal pins such as P0-P3. I connected a 47k resistor between each S pin and ground to ensure the chip control lines don't float. The truth table shows how control the chip S inputs to select between the sixteen I lines. Your ssc-32 control programming would set the ssc-32 control signal pins in the logic desired to align the desired chip input line to the ssc-32 analog input pin. An example might be #0H #1H #2H #3H <CR> to align I15 to the analog input pin. Then you would issue a command like VA<CR> to read the current input value of that analog input pin.

Hi Nikatlas,
This is Laracroft,
I read your post, your confusion about which language is better for programming on laptop specially when if you want to use serial port.
Your solution is to use Java Language which is open source and API is available on http://www.sun.java.com for accessing serial port of your system.
You can also find some tutorial to use this API.
Stay connected to this forum.
