Intercom Interface Crestron C2N-IIF
AV IO
This nine-position terminal block connector is used to receive a
microphone’s output signal, a video camera’s output signal, and a
doorbell switch closure. This connector also provides 12 VDC power to a
video camera (if equipped), and speaker-level audio to a door station
speaker.
Indicators, Buttons, and Controls
The indicators, buttons, and controls of the C2N-IIF are described in the
following paragraphs.
PWR (Power)
This LED illuminates when 24 volts DC is supplied to the C2N-IIF.
NET
This LED illuminates when communication between the control system
and the C2N-IIF is established (the unit is polled on the network).
Illumination indicates that the SIMPL Windows program currently
loaded has a network device defined at the same Net ID as the C2N-IIF.
The LED flashes when communication with the processor occurs.
SETUP LED and Pushbutton
The C2N-IIF is Touch Settable ID-ready. The SETUP pushbutton and its
associated LED are used for setting a units network ID during the initial
configuration of a Cresnet system or when the device is being
added/replaced. Refer to “Method B (Touch Settable ID)” on page 21 for
detailed information.
MIC VOL (Microphone Volume Control)
The volume of an incoming microphone signal can be raised or lowered
with the potentiometer that is recessed below the top of the enclosure. To
raise the microphone signal volume, turn the potentiometer clockwise
with a small flat-head screwdriver. To lower the microphone signal
volume, turn the potentiometer counterclockwise with a small flat-head
screwdriver.
