Joystick Interface

The user may connect an Aerotech JI (not JBV, or JP4) joystick or their own joystick and switches to the
Soloist (Refer to Figure 5-1). The joystick interlock input in the logic low state may be used to detect the
presence of the joystick. The zero velocity null-point for each joystick is approximately 2.5 volts. A two-
axis joystick requires 2 analog inputs. Each Soloist has only one analog input, unless the -IO option board
is present, so two Soloists may be used for a two-axis joystick.
Subsequent drawings illustrate how to connect the joystick (both single and two-axis) to the Soloist in
various ways, and the cables required to so do.
If two separate Soloists are being used to read the joystick, only one Soloist should be used to provide 5
Volt power to the potentiometers. The second Soloist should connect differentially to the second joystick
potentiometer by connecting Analog Input- to common and Analog Input+ to the potentiometers wiper, as
shown in the following figure.
