E.4.1 Interface
The interface to the Analog I/O is a 9 pin D-sub female connector (J5A). The pinouts are illustrated in Figure E3.

E.4.1 Assigning Analog I/O
The inputs and outputs are configurable and scalable in order to represent force, position or velocity via the Moog
GUI software only.
E.4.2 Single-Ended Inputs
A single-ended input measures the voltage between the input signal and ground. In single-ended mode
the board measures the voltage between the input channel and ground reference (see Figure E4). The
single-ended input configuration requires only one signal connection (wire) per channel and one ground
reference to the external source. Because the board is measuring the input voltage relative to its own
ground, single-ended inputs are more
susceptible to both electromagnetic interference (EMI) and any
ground noise at the signal source.
