S751DA
Two-Way Audio, Multiprotocol Data, and Contact Closure
Overview
The S751DA fiber links provide two-way transmission of audio,
multiprotocol data, and contact closure over one or two multimode
fibers.
Digital Processing
Digital processing of the audio signal along with an audio
signal-to-noise ratio >90 dB allows the audio output to drive balanced
or unbalanced loads and maintain constant audio levels.
Data Translation
The data functions include the unique data translation feature, which
allows one data format to be input and a different data format to be
output. Data formats are selected during installation and can be
easily changed in the field via rotary switch.
Superior Diagnostics
The SMARTS™ diagnostic technology provides an extensive set of
built-in diagnostic tools including an audio test generator to verify
audio channel operation. LEDs provide a visual indication of the
operating status of the audio, data, and contact channels as well as
the optical signal strength.
