Control Interface and Signals Figure 3 shown the schematic of the control interface and some signals processing circuit which are related to the interface. A 34 pin dual row connector connect the power board and the control board. Table 1 is the signals on the connector. For noise immunity reason, all of the analog signals are differential. The voltage range of the analog signals is 0−1 Vp−p. The voltage level of all digital signals is 3.3 V.
