The B742AV high-performance broadcast-grade fiber transmission system supports
composite video and two channels of line-level audio. The all-digital processing
platform features 10-bit video processing coupled with 24-bit dual channel audio
processing. This advanced design enables the B742AV to exceed RS250C short-haul
video performance as specified in the EIA-250C standard.
Dual 10-segment LED displays provide for complete monitoring of transmitter and
receiver operation. Signals monitored include input video, output video, audio input
and audio output levels and the received optical signal. For added flexibility dual range
audio levels for the two audio channels can be configured for (-10 dB to +8 dB) or
(0 dB to +18 dB) operation. Balanced 600 ohm, hi-Z or unbalanced operation for
input audio. The audio output stage will drive balanced 600 ohm audio, balanced hi-Z,
and unbalanced hi-Z audio loads. The optical transmission system operates at
1300 nm over 62.5 µm multimode fiber. At 1300 nm, transmission distances up to
6 km (3.7 miles) are possible. The front-panel LED display when switched to the test
mode on the receiver has the capability to display the received optical level. This
built-in test feature aids in the installation process as it easily measures the actual
optical loss in the fiber run from the transmitter.
FEATURES

• Exceeds EIA-250C short-haul video standard
• Video bandwidth - 7.5 MHz
• Video signal-to-noise ratio > 67 dB
• 24-bit A/D audio processing
• Audio frequency response - 20 - 20 kHz
• Audio SNR > 90 dB, THD < 0.003%
• Balanced or unbalanced audio
• Built-in audio 1.5 kHz test generator
• Multimode fiber
• Optical budget 13 dB at 1300 nm

The S764DAV/S7764DAV fiber link provides one-way dig
ital video transmission
combined with two-way 2-channel digital audio, 2-channel multiprotocol data and
2-channel contact closures. Digital processing of the video signal along with a video
signal-to-noise ratio of > 60 dB assures clean, noise-free video at the receiver.
Digital processing of the audio signal along with an audio signal-to-noise ratio of
> 90 dB allows the audio output to drive balanced or unbalanced loads and
maintain constant audio levels. 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. Interlogix's unique SMARTS diagnostic technology provides
an extensive set of built-in diagnostic tools including a video test-pattern generator
that allows failures to be diagnosed from the monitor, and LED displays for
monitoring video, data, audio, contact and optical signal.
FEATURES
• One-way video and two-way audio/data transmission over one or two fibers
• 9-bit A/D video processing, 24-bit A/D audio processing
• Multiprotocol data: RS-232, RS-422, RS-485, Manchester, Biphase, TTL
and SensorNet
• Unique data translation function
• Local or remote user-configurable data format
