These pins output the binary equivalent of the decoded function tone from the tone remote or the current
scan selected channel. The chart that follows shows the pin designation and output for the decoded
function tone. These outputs can be used to control other logic-driven functions of radios that support
such features.

N OTE : The logic is inverted if the ITA2000A channel selection outputs are set for active high.
If programmable or N/C pins are not used, clip off or secure in a fashion to prevent leads from
shorting together, thus preventing damage to the adapter or the radio.
