LINE INTERFACE
LINE interface used as audio input
External audio devices (e.g. CD player) can be connected to the LINE
interface.
If configured in IRIS-Net this signal can be used for business music. The
C a l l s t a t i o n k i t LINE interface converts a stereo signal to a mono
source.
Supervised PTT interface driven microphone connection
For connecting a supervised PTT microphone to the Call station kit the PTT
in contact on th e PM X -C SK must be used as input to activate the PTT
microphone (like a fireman microphone DBB 9081/00). The PTT function of the
corresponding call station kit must be configured within IRIS-Net software.
Ensure that the correct jumper settings are assigned for the type of
microphone used. The following figure shows the correct assignment of a
DBB 9081/00 for using the PTT input
.

MIC INTERFACE
The mic input is used for a connection to a microphone.
A standard (PC / electret ) microphone (VCC = 3,3 V) may be used.
The following figure shows the wiring assignment.
Connect a LED to the Mic_LED to get feedback if the microphone is activated
or not.
