SOFTWARE OPERATION
The main window is divided in three sections, as follows:
• READ shows the actual value of the RDAC or the value of
the selected 20-TP memory location. These values are
displayed in the resistor, as shown in Figure 4, and are
updated when you read from or write to the part.

from A to W; Right Position, Resistance from W to B
• WRITE has the following options:
• RDAC—changes the RDAC register contents. The
value is in hex format.
• Control Register—updates the control register
contents.
• Save Value To 20-TP—saves into the 20-TP memory
the value that is shown in the display (see Figure 5).
It is necessary to click Write To Par t to write to the
part.

Note that, if the enable program is disabled or the
display value is different from the RDAC register,
Write To Par t does not appear (to prevent errors).
• Reset (software)—sends a reset by software. It is
necessary to click Write To Part to send the
command.
• REGISTER shows the value of the control register.
There are also three buttons that allow the following functions:
• Power-down/Power-up—powers the part down and up.
When the button is clicked, the power-up/-down bit
toggles automatically.
• Reset—sends a reset by hardware.
• EXIT—closes the program (it does not reset the part).
