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

units.

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.

In a stacked conﬁguration, one unit must be conﬁgured

as the Master unit and the others as Slave units. Con-

ﬁguring a unit as a Master or a Slave can be done using

theControlPanelGUIinterface.

Note: In order to use the convenient Control Panel

GUI,LecNet2™mustbeinstalledontheattached

computer system. (See Installing LecNet2™

Software and USB Driver.)

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.

(See Expansion Port Digital Audio Network Interface

Interconnection Diagram.)

CAUTION: Do not connect these ports to each

other on a single unit, and to not cross the

cables between the units.

Master/Slave Conﬁguration

When stacking multiple units, one unit is always set as

the Master and all subsequent units are set as Slaves.
