3.2.2 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 COHX base is the same as the COHX

board, whereas the COD A and COD B modules are specific to the new V3X board.

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.

From Multicam 10.04, 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 XT2+ server. A V3X board with genlock can never

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.
