Pin 2 should not be connected. Pins 4 and 6 do not require connection and are internally connected to GND. The zeroing options are for hardware zeroing (both active low). These functions can also be implemented by sending a serial command (recommended). Typical connections for digital interface are GND, 3.3V, Rx and Tx. Note that the Vh for the serial Tx line will be 3V regardless of the supply voltage. The analog (voltage) output is available only when specified. Otherwise, N/C.
