Note : Selectable discrete outputs sink 50ua of current when off. If used as TCAS Inhibit to a
TCAS processor, this connection may require an external 30k-50k pull-up resistor in order for
the discrete input of the TCAS to be at the proper ‘high’ (unasserted) voltage. If necessary,
check with a voltmeter during installation.
