Rear Panel Connectors
14 100-240 V~ / 50-60 Hz Mains
This three-pole non-heating equipment connector with a ground contact con-
nects the FIRNET controller to the mains power supply. The multi-voltage power
supply unit allows the controller to be connected directly to all mains voltages
ranging between 100 V and 240 V without requiring transformers and the like.
Its maximum power consumption is 40 VA, which corresponds to about 175 mA
maximum current consumption at 230 V mains voltage and about 400 mA at
100 V. Do not connect the device using anything other than a three-pole con-
nector with a ground contact. The mains outlet must also be equipped with a
ground contact. Never use damaged cords, plugs, or sockets.
15 GPIO
This 25-pin sub-D port provides four each floating inputs and outputs for future
firmware versions’ use, for example, to remote-control power amps or switch
controlled devices. Current firmware does not support this feature.
16 Ethernet PC Control Ports
Ethernet ports relay remote control and monitoring data between a PC and
FIRNET controllers via computer networking hardware. The Ethernet X and
Ethernet II connectors are RJ-45 ports (Input X = for cross input,
II = parallel input).
Cabling:
If you do not wish to use further network hardware such as hubs and switches,
connect the PC’s network port to the first FIRNET’s Ethernet X port using CAT5
network cable. Then also use a CAT5 network cable to connect the first FIRNET’s
Ethernet II port to the second controller’s Ethernet X port, and so forth.
Use a CAT5 network cable to connect the FIRNET controller to hubs or switches,
patching the FIRNET controller’s Ethernet II port to the hub or switch’s network
port. To daisy-chain further FIRNET controllers, connect the first FIRNET’s
Ethernet X port to the second controller’s Ethernet II port, and so forth.
Tip: We recommend that you connect all FIRNET controllers to switches. If you
do not, and one controller fails in setups comprising several -connected FIRNET
controllers, the entire networked chain will drop out.

17 AES/EBU IN Digital Audio Input
Connect signal sources with digital outputs to these three-pin female XLR
sockets. Pin assignments are pin 1 = ground, pin 2 = signal, and pin 3 = signal.
The FIRNET controller accepts sampling rates of 48 kHz and 96 kHz, which
may be selected via a menu option.
Input-Output Signal Routing:
The analog INPUT A – that is, the left channel of the digital AES/EBU signal
- delivers the signal to OUTPUT A and OUTPUT B. OUTPUT C and OUTPUT
D receive their signal from analog INPUT B, that is, the right channel of the
digital AES/EBU signal. You can reroute signals in the LIPAN software’s Admin
window.
18 AES/EBU OUT Digital Audio Output
The signal patched into the AES/EBU input can be routed through in digital
format to other devices via this three-pin male XLR port. Pin assignments are
pin 1 = ground, pins 2 and 3 = signal. The FIRNET amplifi es the incoming digital
audio signal to preserve signal quality. If a FIRNET controller drops out, the
signal is routed directly from the digital AES/EBU IN to the digital AES/EBU
OUT via a parallel circuit.
To select the digital input, go to the Admin menu (press ADMIN once), choose
the menu option Input Options (press 1x
S), and then press ENTER to confi rm:
Menu option - ADMIN/Input Options/ Input Source
Synchronization Ports for Analog Audio Signals:
If you wish to address several FIRNET controllers via their analog inputs, you
can use digital AES/EBU IN inputs and AES/EBU OUT outputs to synchronize
these controllers to ensure the audio signal remains coherent.
To do this, connect the first FIRNET controller’s digital AES/EBU OUT to
the second FIRNET’s digital AES/EBU IN. Then connect the second FIRNET
controller’s digital AES/EBU OUT to the third FIRNET’s digital AES/EBU IN,
and so forth.
