Hardware Description & Installation Manual
KMX-3901-OUT front card-edge USB connector
The KMX-3901-OUT output cards have one USB connector, into which you may connect a
mouse, keyboard, or USB flash memory for a software upgrade or data backup. The diagram
below shows the USB connector, between various LED indicators and the Select button, on
the output cards’ front edge. See
KMX-3901-OUT Output Card Interface
on page 60, for a
detailed description of the LED indicators, and
Using the Densité Frame Control Panel
page 63, for more information on the Select button.
Input Cards
The KMX-3901-IN cards are input modules that can be installed in a Densité 3, Densité 3+
FR1, or Densité 3+ FR4 frame, to be part of a Kaleido-Modular-X multiviewer system.
SDI input cards are available with eight or 16 inputs. Two different 16-input card models are
available to drive one or two output cards for two or four possible multiviewer outputs.
A KMX-3901-IN-IP input/output card is available with two (1+1 redundant) 10 GigE ports
supporting up to 6 SMPTE ST 2022-6 IP video inputs (3G/HD/SD). This input card can drive
one output card, for two multiviewer output. In addition, one or both multiviewer outputs
can be looped back into this card’s SDI inputs and made available over IP, as a SMPTE-2022-
6 stream.

Notes
• Early revisions of the KMX-3901-IN input cards (see
not
fully compatible with the Densité 3+ FR4 frame. These
cards are unable to properly extract the URS signal from the frame. Should
you decide to rely on the card's external reference input (instead of the
URS signal), to genlock your signals, the card will operate properly,
however URS time code extraction will be unreliable. Grass Valley can
modify these cards if needed (see
