2.2.CopperHead FS-790 Transceiver System concepts
The Telecast CopperHead FS-790 Transceiver System is a camera video, audio and data multiplexing
system that installs between the JVC ProHD GY-HM790 video camera and its power source and connects
via a single fiber optic cable to a Base Station in a truck, studio control room, or other video production
facility. All video, audio and data usually carried on Triax or multi-core cable is sent, bi-directionally, over
a single lightweight fiber over distances as long as 5 km or more.
The Camera Unit is attached directly to the camera. A battery, battery power adaptor or a Telecast Fiber
Power Wafer power supply is attached to the Camera Unit. Battery mounts accommodated are the
Anton-Bauer and the V-Mount.
The CopperHead FS-790 Transceiver System consists of two main components:
1. The CopperHead FS-790 Camera Unit – this unit has two options: a) the battery physical interface
system and b) the fiber connector.
2. The CopperHead FS-790 Base Station – this unit has three options: a) the power configuration, b) the
fiber connector and c) the intercom interface.
Typically options are determined at the time of product order and the units are delivered pre-configured.
Some options can be field changed by qualified personnel. This manual describes each of the possible
options.
The unique design of the CopperHead KA-F790 Camera Unit allows for the majority of signal connections
between the JVC ProHD GY-HM790 video camera and the CopperHead to be carried over a 68 pin
connector internal to the camera and CopperHead Unit.
The signals carried internally between the camera and the Camera Unit are:
SDI – HD/SDI Camera Video
VBS (Analog) Camera Video
VBS Video (Genlock) to Camera
VBS Video (Return Video) to Camera
Audio 1 from Camera
Audio 2 from Camera
Timecode to and from Camera
Camera Control
Camera Tallies (Red and Green)
