Line Level Stereo Audio (Analog) or E&M + Data (RS-232/422/485) Systems
FiberPlex TD-7280 Fiber Optic Isolator/Converter/Modem - line level stereo audio or E&M with data and contact closures; industrial packaging

Overview
Elegantly simple yet packed with an advanced feature set, the TD-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 (RS-232/422/485) and a bidirectional pair of ‘form C’ contact closures are included.

The combination of audio and signaling provides a seamless solution for 4-wire E&M applications, push-to-talk, intercom, audio distribution, railway signaling, and more

Various advanced routing and networking options are available via DIP switch setting.

In point-to-point mode basic audio inputs one unit map directly to audio outputs on the other unit and serial data and contact closures are a direct connection.

In 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.

In Intercom or “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.
