4.2 Input Signal Path

This section describes the circuitry of the input signal path.

J1 is the main connection terminal. Pins 1 and 2 of J1 are used to tie the system ground to the EVM ground. Pins 3 and 4 are tied to IN+, and Pins 5 and 6 are tied to IN–. There are two pins each for IN– and IN+ for convenience, as well as current capabilities. For currents greater than 5 A, ensure that all pins of the terminal blocks are populated.
