The VADT/VADR-9004 system consists of the VADT-9004 transmitter and
VADR-9004 receiver. Both units utilize pure digital 10 bit encoded
modulation to transmit 4 individual high quality video signals, 4 hi-fi
stereo (or 8 mono) audio channels, and 4 data channels on a single fiber.
Video signals are an in accordance with NTSC, PAL and SECAM specifications.
Audio channels can be balanced or unbalanced. Data can be RS-232, RS-422 or
TTL as specified by the user
Both multi-mode and single-mode versions are available and installation is
adjustment free. In addition, indicators are provided on both units to
continuously indicate the presence of video, audio and digital signals as
well as the presence of operating power making system troubleshooting
simple.
