3.2 VIDEO AND REFERENCE BOARDS
3.2.1 V3X BOARD “DUAL POWER”
Important
It highly advised not to remove a V3X board from the EVS server. Should
you have to do so, manipulate the board very carefully, making sure it is
not exposed to mechanical or electric shocks.
DESCRIPTION
The V3X board is divided in 3 parts: a base board identified as COHX base (rear
section and center extension), and two modules identified as COD A V3X (front
left), and COD B V3X (front right).
The COD A V3X and COD B V3X modules are the actual CODEC modules, each of
them being able to be configured by software either as an encoder (for a record
channel) or as a decoder (for a play channel). The COD V3X modules are SD, HD
and 3 Gbps capable.
They support the following new features:
• Full resolution 3D HD on a single V3X module (Dual Link HD SDI or single link
3Gbps)
• 1080p 50/59.94Hz video standard on a single V3X module (Dual Link HD SDI
or single link 3Gbps)
There are 2 versions of the V3X board: one with genlock, one without genlock.
The genlock model can easily be identified by the presence of 3 quartz
synthesizer at the back of the COHX base board, on the right-hand side, and by
the presence of the GLK and PSU OK LEDs on either side of the DIN connector at
the centre front of the board. Note that a V3X board with genlock must
be installed
as V3X #1 in first position (slot 2) in an XT3 server. A V3X board with genlock can
never be installed in any other slot, and thus cannot be used instead of V3X #2 or
#3. Doing so will result in conflicting electrical signals inside the system.
