A1 and A2 are analog input channels on compatible telemetry receivers. A1 is most often used to report receiver voltage, and A2 pack voltage. A1 and A2 can report any value that can be represented as an analog voltage between … Continue reading
Glossary
A function used in Logical Switches that compares selectable source “a” to a second selectable source “b” using ‘Greater Than’ as the comparator. The function takes the value of TRUE when the first source is greater than the second and FALSE when the first is … Continue reading
A function used in Logical Switches that compares selectable source “a” to a chosen constant “x” using ‘greater than’ as the comparator. The function takes the value of TRUE when the value of the selected source is greater than the chosen constant and FALSE when the source is … Continue reading
A function used in Logical Switches that compares selectable source “a” to a second selectable source “b” using ‘Less Than’ as the comparator. The function takes the value of TRUE when the first source is smaller than the second and FALSE when the first is greater … Continue reading
A function used in Logical Switches that compares selectable source “a” to a chosen constant “x” using ‘less than’ as the comparator. The function takes the value of TRUE when the value of the selected source is less than the chosen constant and FALSE when the source … Continue reading
A function used in Logical Switches that compares selectable source “a” to a second selectable source “b” using ‘exactly equal’ as the comparator. The function takes the value of TRUE when the two sources are equal and FALSE when they are not equal. Two fields labeled V1 … Continue reading
A function used in Logical Switches that compares selectable source “a” to a chosen constant “x” using ‘exactly equal’ as the comparator. The function takes the value of TRUE when the source and the constant are equal and FALSE when they are not equal. Two fields … Continue reading
A function used in Logical Switches that compares selectable source “a” to a chosen constant “x” using ‘Approximately equal’ as the comparator. The function takes the value of TRUE when the source and the constant are approximately equal (+ or – 0.9) and FALSE when … Continue reading
A timer trigger that counts up or down continuously so long as the radio is turned on and that model is selected. Sometimes used with Persistent as a totalizer for time.
