6.2.2.2 Jumper selections on the OPT-A1 basic board
The user is able to customise the functions of the frequency converter to better suit his needs by selecting
certain positions for the jumpers on the OPT-A1 board. The positions of the jumpers determine the signal
type of analogue and digital inputs.
On the A1 basic board, there are four jumper blocks X1, X2, X3 and X6 each containing eight pins and two
jumpers. The selectable positions of the jumpers are shown in Figure 6-29.
