Product Information Manual

PPrroodduucctt FFeeaattuurree

The VC-P840U provides a direct video signal connection between the JVC’s HD studio Viewfinder (VF-HP840U) and the
GY-HD250U/GY-HD200UB. This cable carries the camera’s RGB, CMP or a Y signal depending on the Camera’s VF
menu setting. The Tally and Preview signal is sent from the camera to the VF-HP840U via serial communication. This
cable does not provide power to the camcorder. It is approximately 2ft long.

This cable gives the Studio System Integrator the flexibility of using the VF-HP840U in studio applications that do not use
the studio sled (KA-HD250U); such as when a third party CCU manufactured by Telecast Fiber or Camplex is used.
Owners of the GY-HD250U and GY-HD200UB also have the choice of using the high definition VF-HP840U in non studio
applications that require a viewfinder with built in features such as safety markers, focus assist, and zebras in non studio
applications that require critical focus and VF functionality.

Required Camcorder and VF-HP840U settings

When using this cable:

• Set the GY-HD250U/GY-HD200U(B) Camera’s “VF Signal” in the “LCD/VF” menu group to “COMPONENT”.

• Set the VF-HP840U’s Dip Switch4 to “OFF”. This terminates the video inputted into the studio Viewfinder with 75

ohms.
Dip switch is located on the bottom of the VF-HP840U under a cover plate. Remove two screws from cover plate and take
cover off to expose dip switch
