Fiberplex TD-7280-C Line Level Stereo Audio Transceiver with PTT Serial Data

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 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 sampli
