Basic Application Default I/O Configuration

GND terminals 3, 7 and 13 are internally connected.

For the STANDARD Application, input signals at DIN1 and DIN2 are
programmed as a pair using parameter 2.1.

Connect CMA/CMB inputs to either logic high or logic low depending
upon your application. Refer to the SVX9000 User Manual and
SVReady Application Manual for additional information.
