EVAL-ADM1030/31
Preliminary Technical Data
VISUAL DISPLAY
The visual display tab allows readings to be displayed
graphically on bargraphs or line graphs.
When the visual display is selected for the first time the
value displayed on the bargraph is the value of local
temperature. To display one of the other values e.g. remote
temperature or fan speed click on the relevant bar graph
button.
FAN SPEED CONTROL
The user may also control fan speed using the PWM duty
cycle select method in the visual display window. This may
be done by adjusting the position of the fan speed control
slider to the required PWM. The duty cycle is displayed as
a percentage at the bottom of the slider. The value written
to the Fan Speed Config Register is displayed on the slider
button.
Y _{EASY SETUP}
R _{The line and bargraphs can also be started by clicking on}
INA ^the
button. This also sets limits for
L _{both local and remote temperature. When you click “Easy}
IM ^A _{Setup” the software prompts the user to ensure that S1 and}
EL ^{IC S2 are switched to AIN. This is because Esay Setup sets up}
the ADM1030/31 for a 2-wire fan. Easy Setup also places
PRTECHDNATA ^{the ADM1030/31 under simple software control.}
