The 285 features a digital, fiber
optic transmission technology, capable of providing crisp audio,
little or no maintenance, high function reliability, and low operating
cost.
The 285 Series is a low-cost and high-performance
Digital Fiber Optic Audio and Data Transmission System, providing
simultaneous transmission of digitized audio and serial data. The
standard 285 system is designed to transmit one (1) audio channel
and one (1) serial data (RS-232/ RS-422) channel over one or one
pair of multimode or singlemode fiber. No user adjustments are required
in the 285 system, enabling quick setup and trouble-free operation.
The 285 Series comes with two packaging options: a rugged, standalone,
and compact unit, or a plug-in card for a card cage system. Panel
connectors are provided for audio and data (terminal block connector)
and fiber connection (ST-type for singlemode and multimode fiber).
The 285 Series is easily monitored using LED indicators for power,
optical link, and audio/data activity. The standalone units are
powered by +12 VDC. Due to its digital transmission design, the
285 Series is capable of addressing a variety of non-standard configurations.
