Installation
Front Card Edge
Space constraints on the KMV-3901/3911 rear module do not allow HDMI connectors with a
screw securing mechanism. For this reason, a special locking mechanism is incorporated on
the rear panel. The mechanism is adjustable for many sizes of cables and shells.
In the case of a KMV-3901/3911 with both heads activated, the two HDMI cables should
have same-size plug connectors; otherwise the locking mechanism will not hold the
smaller connector securely. If your cables have long plug connectors that will not fit the
special locking mechanism, you can secure them with a cable wrap threaded through the
hole in the bracket.
HD-SDI Monitoring Output Connectors
There are two HD-SDI monitoring outputs: one associated with Head 1, and one with
Head 2 if enabled. The HD-SDI output resolution depends on the current resolution at the
corresponding HDMI output, and, in the case of a 1080-line resolution, on the scan format
(interlaced, progressive) configured in XEdit for this output head.

USB Connector
This USB connector is accessible when the front panel of the Densité frame is open. The USB
connector is used for the following tasks:
• Upgrading the Kaleido-X Software and KMV-3901/3911 firmware, by using a USB key
prepared with the appropriate upgrade package. Refer to the Kaleido-X Release Notes
for details.
• Controlling some features on the monitor wall, by using a mouse (e.g. showing or
hiding the monitor wall dashboard, dismissing the confirmation message that appears
