REF BNC Connector
The REF BNC connector is the input for synchronizing the crosspoint switch
timing of KUMO to your house video signals. Apply an analog NTSC, PAL, or
Tri-level sync signal to this input. Be sure to terminate the second BNC with a 75
Ohm terminator, or if you loop to other equipment terminate the last connected
device.
When reference is present, KUMO will switch at the SMPTE RP 168 designated
switch point with respect to the reference input. If no reference is present, the
KUMO will switch based on its internal clock.
Video Inputs and Outputs
Depending on your KUMO model, up to 64 SDI video inputs and outputs can be
connected to the video input and output BNC connectors.
Normal Mode
In Normal mode, each input and output BNC routes an individual signal.
Dual and Quad Modes
In Dual mode, inputs and outputs use adjacent pairs of BNCs for each routed
signal. In Quad mode, four adjacent BNCs are used for each routed signal. See
RS-422 Connector
KUMO routers include a RS-422 female DB-9 connector for making serial
connections to other equipment. This control connection enables interoperability
with other devices, including those that use GVG Native Protocol. See
Control Specifications (Routers)" on page 62
for more information.
Older Model RS-422 Adapter
Older KUMO 1604, 1616, and 3232 routers (serial numbers ending in -R0) needed
an RS-422 adapter for proper serial control operation (
). This adapter was
shipped with those older model routers. Be aware of this fact if your facility has a
mixture of older and newer KUMO routers that use RS-422 control.
NOTE: KUMO routers with serial numbers ending in -R1 or higher do NOT require the
adapter, and KUMO 6464 models do NOT require the adapter.
