Various advanced routing and networking options are available via DIP switch setting. These include the following:Point to point modeBasic configuration. Audio inputs one unit map directly to audio outputs on the other unit. Serial data and contact closures are a direct connection.point to pointBroadcast ModeOne 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.FOI-7280-broadcast-300x37Intercom / Loop modeOne 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.FOI-7280-loop-300x45

Overview

Elegantly simple yet packed with an advanced feature set, the FiberPlex Technologies, FOI-7280 is a powerful problem solver when it comes to routing audio or transporting E&M signals. 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. The combination of audio and signaling provides a seamless solution for 4-wire E&M applications.

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.
