Fiberplex TD-7280-C Line Level Stereo Audio Transceiver with PTT Serial Data
Elegantly simple yet packed with an advanced feature set,the TD-7280 is a powerful problem solver when it comes to routing audio or transportingE&M signals. The unit converts line level, stereo analog audio to fiber forlong or short haul transport. In addition to the audio, a multi-format serialdata connection (RS-232/422/485) and a bidirectional pair of `form C’ contactclosures are included.
The combination of audio and signaling provides a seamlesssolution for 4-wire E&M applications, push-to-talk, intercom, audiodistribution, railway signaling, and more
Various advanced routing and networking options areavailable via DIP switch setting.
In point-to-point mode basic audio inputs one unit mapdirectly to audio outputs on the other unit and serial data and contactclosures 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 masterare sent to all the slaves, which output the data on their respective ports. Nocommunication is sent from the slaves to any other units.
In Intercom or “Loop mode” one unit is configured as themaster, which sets the clock and sampling rate. It polls the loop, with eachunit in the loop adding its own input to the aggregated sample, gated by itspush to talk, if enabled. When the sample returns back to the master, it thensends out that aggregated sample as the output for all units in the loop. Allunits forward the aggregated output around the loop until it returns to themaster, which discards it. Serial data from the master is replicated on allslaves, and serial data from the slaves is aggregated to output on the master.
