Example 1: The RBI input and RBO output of each digit are open when zero suppression is not being used. Example 2: Wired as shown to display only 0 for the rightmost digit when zero suppression is being used. Example 3: Zeros are suppressed only for the digits on the left of the digit where the decimal is lit when both zero suppression and a decimal point are being used. Example 4: Zeros are suppressed to the right of the first digit below the decimal point when both zero suppression and a decimal point are being used. If the first-to-fourth-digit values are all 0 and the decimal point is lit at the fourth digit, 0.0@@ will be displayed. (There is no data in @@.) Note: Use RBO output for the RBI input connection only.
