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.
