RJ45 Ethernet
Connector
The RJ45 Ethernet connector allows you to connect KUMO to an Ethernet 10/100/1000
Ethernet LAN using CAT5 cable as explained in the section that follows. Multiple
configurations are possible, including standalone control, a local LAN, or a WAN.
ID and Reset
The ID LED lights when you use the web interface to identify the KUMO unit you are
controlling. The Reset button (pinhole) below the LED allows a safeboot reset of the unit
as explained in Chapter 3:
REF BNC connector
The REF BNC connector is the looping input for synchronizing the switching timing of
KUMO to your house video signals. Apply an analog NTSC, PAL, or Tri-level sync signal to
this input. Also be sure to connect a terminator to the second connector, or if you loop
from that connector to other equipment, be sure to terminate the connection at the
other equipment.
When reference is present, Kumo will switch in vertical interval with respect to the
reference input. If no reference is present, the Kumo will switch at random times.
Video Inputs and
Outputs
Depending on your KUMO model, up to 32 SDI (SMPTE 259/292/296/424) video inputs
and outputs can be connected to the video input and output BNC connectors.
Normal mode
In Normal mode, BNC inputs and outputs have a one-to-one relationship with the SDI
signals being routed.
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
RS-422 DB9
Connector
KUMO includes an RS-422 female DB9 connector for making serial connections to other
equipment. This control connection enables interoperability with other devices,
including those that use GVG Native Protocol.
