5.2.1 Front view
The front of the network controller (see figure 5.2)
contains the following:
1 Loudspeaker - A loudspeaker for audio
monitoring purposes. The loudspeaker is muted
when monitoring headphones are connected to the
monitoring headphones output (4).
2 Menu display - A 2x16 character LCD display
gives information about the network controller (see
section 5.5).
3 Menu button - A turn-and-push button to operate
the menu (see section 5.5).
4 Monitoring headphones output - A 3.5 mm
(0.14 inch) jack socket to connect headphones for
audio monitoring purposes. The loudspeaker (1) is
muted when headphones are connected.
5.2.2 Rear view
The rear of the network controller (see figure 5.2)
contains the following:
5 Ground - A connection to electrically ground the
network controller.
6 Audio inputs - Four audio inputs for receiving
audio signals from analog audio sources. Two of the
audio inputs are selectable between microphone and
line. The other two audio inputs are fixed line inputs.
Each audio input has a XLR as well as a double
cinch connector (see section 5.3.6).
7 Audio outputs - Four audio outputs for extracting
analog audio signals. Each audio output has a XLR
as well as a double cinch connector (see
section 5.3.7).
8 Voltage selector - A switch to select the local
mains voltage (see section 5.3.2).
9 Mains on/off switch - A switch to switch the
network controller on and off (see section 5.3.2).
10 Fuse holder - A fuse holder with a fuse that
protects the power supply of the network controller
(see section 5.3.2).
11 System bus - Two system bus connectors to
connect the network controller to other Praesideo

12 Ethernet interface - An interface to connect the
network controller to external logging and
configuration devices/systems. This interface usually
will be used to connect a configuration PC (see
section 5.3.5) or an open interface client to the
Praesideo system.
13 Control inputs - The control inputs can be used to
receive signals from third party equipment that must
trigger actions in the Praesideo network (see
section 5.3.8).
14 RS232 interface - For factory/development use.
15 Control outputs - The control outputs can be used
to send signals to third party equipment to trigger
actions generated by the Praesideo network (see
section 5.3.9).
16 Battery 48V - Back-up battery supply (see section
5.3.3).
17 Mains inlet - A socket to connect the network
controller to the mains (see section 5.3.2).
