Each choice opens a sub-menu with an array of the logical signals and available connector
pins. The screen for digital inputs looks as follows:
In the top row, the available connector pins (D1 - D4) are shown. In the left column, the
logical signals are listed. The symbol indicates that there is a connection between the pin
and the logical signal. A signal is linked to an input pin as follows:
• move the cursor with the arrow keys and +/- keys to the necessary intersection
• press ENTER
To erase a connection, go to it with the cursor and press ENTER. The connection will
disappear.
D1 - D4 refer to the 4 digital inputs of the DAC. ‘0’ is a logical FALSE. If a signal is linked to
this, it is always regarded as low (not active). ‘1’ is a logical TRUE. If a signal is linked to
this, it as always regarded as high (active).
For digital outputs the method works similar. In the case of outputs, several logical signals can
be mapped to the same output pin. They are processed as a logical OR: if one or more of these
signals become high, the output pin becomes high.
