Camera Interface Signal Paths
The FS-900 Triple Studio Camera Interface System is
a camera video, audio, ethernet and data multiplex-
ing system that installs between three separate JVC
ProHD GY-HM890U video cameras and their power
sources in addition, each camera connects via a single
fiber optic cable to a common Base Station in a truck,
studio control room, or other video production facil-
ity. All of the video, audio and data is sent bi-direc-
tionally between the Base Station and each camera
over three separate single fiber cables, one between
each camera and the common Base Station.
The Camera Head Unit is attached directly to the
camera. The Camera Head unit is designed to allow
the majority of the signals that connect between the
Camera and itself to flow thru a 68 pin connector
internal to the Camera and the Camera Head unit.
The FS-900 Triple Studio Camera Interface System
consists of the two main components:
1. The FS-900 Base Station
2. The FS-900 Camera Head
Model numbers of available options:
FS-900BS1S - Base Station with SMPTE connectors
FS-900BS1N- Base Station with Neutrik connectors
