6.3.2 Connect 'PACE-Net' Ethernet
The digital audio matrix PC2003-A1 provides 2 'PACE-Net' copper Ethernet (CAT5)
RJ45 sockets (A and B) at the rear of the housing.
Connect an 'Ethernet switch (2x4/2)' PN2001-A1 or a 'Planet IGS-10020MT
Ethernet Switch' PN2005-A1 to extend the amount of 'PACE-Net' Ethernet
connections. The Ethernet switches are used to connect further Cerberus PACE
modular or Cerberus PACE Compact systems, 'PACE-Net' call stations or a PC
with the configuration tool 'PACE-Design' installed.

Always connect port A (ETH A) with an Ethernet switch.
A redundant Ethernet connection can be established by connecting socket port B
(ETH B) with an Ethernet switch. It can be the same switch or, for higher
redundancy, another Ethernet switch in the system. If the connection on port A
fails, the digital audio matrix uses automatically port B for the communication.
6.3.3 Connect general fault relay
The digital audio matrix PC2003-A1 provide one general fault relay output.

The general fault relay contact is used to display the operating status of the digital
audio matrix. The relay is activated (NO and C are connected) in regular operation
and is released in case of a fault.
