The screen shot above illustrates the default I/O point assignment that the VP4-2330
is shipped with. It may not be necessary to make any changes. The most common
change that will be made is to assign analog/universal inputs (A/UI) to Binary Input
objects instead of Analog Input objects. The Binary Input objects would then be
configured as discrete or dry contact inputs on the Objects page.
Assignments are made or changed using the top line of input windows. The large
window is for display only. The steps for assigning an I/O point to a BACnet object are
as follows:
(i) Scroll the number on the left to the desired physical I/O point number. You can also
double click on a line in the large display window to directly select that point.
(ii) Select a BACnet object type from the drop-down list on the right.
(iii) Scroll the number on the right to the BACnet object instance desired.
