5.2.5 Analog Inputs (RCM4000 only)

unsigned int anaInConfig(unsigned int instructionbyte, unsigned int cmd, long baud);

Use this function to configure the A/D converter. This function will address the A/D converter in Register Mode only, and will return an error if you try the Direct Mode. Appendix B.4.3 provides additional addressing and command information.
