DANI Bus (expansion ports)
Expansion I/O ports
The four RJ45 connectors on the rear panel are used to
interconnect LecNet2™ units together. These ports are
only used to transfer digital audio information via the
Digital Audio Network Interface (DANI) between the DM
Series processors that are interconnected.
WARNING: The Expansion I/O connectors are
NOT EtherNet, CobraNet or any other network
based device interconnects. Connecting them
to Ethernet, CobraNet or other network based
device may cause damage to either unit.
To connect the Master/Slave units, plug one end of a 12
inch Cat5e cable (two are supplied with each with unit)
to the transmit (TX) port on the Master unit, and con-
nect the other end to the corresponding receiver (RX)
port on the Slave unit immediately below the Master.
Repeat this procedure with the second Cat5e cable.

Interconnection Diagram.)

Interconnection Diagram
The DMPA12 amplifier, like all DM Series processors,
are interconnected via the Expansion ports on the
rear panel. The correct wiring to stack multiple units
is shown here. To ensure proper signal and data flow,
the TX port on a slave connects to the RX port directly
above it in the stack. The TX port on the upper unit con-
nects to the RX port on the unit below it.

Audio signals and data are propagated through the DANI
bus via Cat5e cables connected to the Expansion ports
on the rear panel.
