It is possible to connect the following to the control
inputs/outputs connector:
•
Press-to-talk (PTT) key. See figure 18.8 for a
connection diagram. The two resistors must be
placed in the circuit, because the contact is always
supervised by the system software.
•
Internally powered lamp or LED. See figure 18.9 for
a connection diagram.
•
Externally powered lamp or LED. See figure 18.9 for
a connection diagram.
•
Externally powered relay. See figure 18.11 for a
connection diagram.
