FOI-7280 / TD-7280

LINE LEVEL STEREO AUDIO TRANSCEIVER WITH SERIAL DATA AND CONTROLS

Overview
Elegantly simple yet packed
with an advanced feature
set, the FiberPlex
Technologies, FOI(TD)-7280
is a powerful problem
solver when it comes to
routing audio. The unit
converts line level, stereo
analog audio to fiber for
long or short haul
transport. In addition to
the audio, a multi-format
serial data connection and a
bidirectional pair of contact closures are included.
What’s the difference between the FOI and the TD versions?
Functionally, the FOI-7280 and TD-7280 are identical. The only differences are the packaging and power
supply. The FOI-7280 is part of the FOI line of products designed for ruggedized military applications
while the TD-7280 is housed in the commercial ‘Throw Down’ packaging.

Routing
Various advanced routing and networking options are available via DIP switch setting. These include the following:

Point to point mode
Basic configuration. Audio inputs one unit map directly to audio outputs on
the other unit. Serial data and contact closures are a direct connection.

Broadcast Mode
One unit is configured as the master, which sets the clock and sampling rate.
Analog and serial inputs to the master are sent to all the slaves, which output
the data on their respective ports. No communication is sent from the slaves
to any other units.

Intercom / Loop mode
One unit is configured as the master, which sets the clock and sampling rate.
It polls the loop, with each unit in the loop adding its own input to the
aggregated sample, gated by its push to talk, if enabled. When the sample
returns back to the master, it then sends out that aggregated sample as the
output for all units in the loop. All units forward the aggregated output
around the loop until it returns to the master, which discards it. Serial data
from the master is replicated on all slaves, and serial data from the slaves is
aggregated to output on the master.
