The Analog Input/Joystick
Module adds two 0 to 5
volt analog input channels
to the MicroLYNX System.
Both channels can be used
for data aquisition, or either
channel can be used to
directly control motion.
This offers the user the
capability of receiving
input from a variety of
analog sources such as
temperature or pressure
sensors, and then control-
ling events based upon
those inputs.
The user-selected Joystick
channel can be pro-
grammed to set the range,
zero, deadband and sensi-
tivity.
Each channel uses a 12 bit
D/A converter for better resolution as well as a fixed single pole analog filter
with a cutoff frequency of 658 Hz to reduce the electrical noise that can be
