Cabling Of Stacked Units
In a stacked configuration, ASPEN processors must
be interconnected as shown here. Each Slave unit in
a stack gathers data and audio signals from the unit
below it, adds its own signals and passes the total on to
the unit above it. At the top of the stack, the Master unit
gathers all signals from below, adds its own and then
sends the total back down the bus to all Slave units
below it. In this manner, all Slave units have access to
all inputs on any unit in the stack.
Each circuit board has an upper and a lower CAT-5 con-
nector. Since there are two circuit boards in a 2RU unit,
the circuit boards are connected in the same manner as
if they were in separate chassis. The ASPEN bus is bi-
directional, handling data and audio signal forward and
back propagation through a single cable connection.

ASPEN PORT
The processors automatically configure themselves for
Master and Slave status as determined by the cabling.
If a unit is connected to another unit above it through
the upper connector, it is automatically configured as
a Slave. If there is no unit above it, then it becomes a
Master.
