Below is some of my arduino test code (for version 18) that can interface with the ssc-32. The ssc-32 TTL tx/rx/ground is connected to the arduino rx/tx/ground pins. The ssc-32 board probably can be powered from the arduino +5v if needed (but no servos!). The below code can take a control string entered in the arduino serial monitor and send it to the ssc-32. The bottom code is for use with the arduino/ethernet shield combo. HTTP request are sent from a web page to the arduino, which processes the request and sends the control strings to the ssc-32 via its serial output (and also to the serial monitor. This is part of my routerbot testing.
Code:
//zoomkat 9-9-10 simple delimited ',' string parce
//from serial port input (via serial monitor)
//and print result out serial port
// CR/LF could also be a delimiter

#include <WString.h> //provides easy string handling
String readString = String(100);
void setup() {
Serial.begin(9600);
}
void loop() {
//expect a string like wer,qwe rty,123 456,hyre kjhg,
//or like hello world,who are you?,bye!,
while (Serial.available()) {
delay(10); //small delay to allow input buffer to fill
if (Serial.available() >0) {
char c = Serial.read(); //gets one byte from serial buffer
if (c == ',') {break;} //breaks out of capture loop to print readstring
readString.append(c); } //makes the string readString
}
if (readString.length() >0) {
Serial.println(readString); //prints string to serial port out
readString=""; //clears variable for new input
}
