Installation
8995 Module Placement For Genlock Timing
Before installing the 8995 module, you will first need to determine if and
how you want to use a genlock reference or the available frame reference
buses. The genlock timing from an 8900GEN-SM submodule can be uti-
lized in several ways. Refer to the
8900GEN-SM GeckoFlex Genlock Instruc-
tion Manual available online for a complete overview of using the genlock
reference.
This as well as all other modular product manuals are available online at
the following URL on the Grass Valley web site:

In addition to the capability of providing a local external reference to this
specific 8995 module with an 8900GEN-SM submodule installed, slots 1
and 3 of the Gecko Flex frame have been specifically designed to distribute
an independent frame bus reference transmitted from the 8900GEN-SM
submodule mounted on an 8995 module (or other GeckoFlex module with
this capability) configured for this purpose. The external reference con-
nected to the corresponding Genlock Loop BNCs can be distributed to
other modules in the frame that accept a genlock reference.
If another 8995 module has already been configured and installed for frame
bus distribution, you may configure this module’s output timing to lock to
the Frame Bus 1 or Frame Bus 2 reference from the other 8995 module. In
this case, the 8995 does not require the use of an additional 8900GEN-SM
submodule.
The use of the genlock reference is determined by the setting of the Output
Timing on the System Config web page of the module and module place-
ment in the frame and jumper configuration as summarized below.
• Local Reference – the 8995 with an 8900GEN-SM submodule can have
a local external reference connected to one of the corresponding
Genlock Loop BNCs. This external timing reference will be fed to this
specific 8995 module only.
• Frame Reference 1 or 2 – when an 8995 with an 8900GEN-SM sub-
module is installed in slot 1 and/or slot 3, a frame timing bus can be
enabled to distribute the external reference connected to the corre-
sponding Genlock Loop BNCs on the rear module to all modules in the
frame that can accept a genlock reference. slot 1 provides Frame Bus 1
and slot 3 provides Frame Bus 2.
• Input Video – when no 8900GEN-SM submodule is installed on the
8995, the Output Timing can be set to Input so the output timing will
follow the input to the module.
