Data may be written to all registers that are Read/Write,
(refer to data sheet for more information). When the Read/
Write tab is first selected, none of the registers have been
written to, and they contain their default values.
Registers may be written to in two ways. Clicking on a bit in
the Read/Write display will toggle its value between 0 and 1.
This is useful where a function is controlled by setting or
clearing individual bits in a register, for example setting or
clearing the FAN_OFF bit in the configuration register.
The entire contents of a register may be changed by typing a
Hex or decimal value in the text boxes of the Write display.
The button will change from green to red and the new value
can be written to the register by clicking on the button.
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 at the time viaual display was selected. To
switch the bargraphs to contineous monitoring of the local
and remote temperatures click on either the local or remote
temperature buttons on the bargraph display.
Clicking on these buttons will also cause
the line graphs to become active. You can zoom in or out of
the line graphs using the arrows on both the time and
temperature axes.
This is useful where a register contains a numeric value such
as a temperature limit.
EASY SETUP
The line and bargraphs can also be started by clicking on
the
button. This also sets the limits for
both local and remote temperature. The low limit is 0°C
and the high limit is 90°C for both local and remote.
