2.3.1 Ethernet Port
The Ethernet port must be configured before it can be used to download files into the KMV-3901/3911.
See section 3.4.4.
2.3.2 GPI / RS-422 Connector
The DB-26 GPI connector carries 8 GPI IN and 2 GPI OUT lines, plus the RS-422 interface. The pinout of
this connector is:

2.3.3 HDMI Mosaic Output Connectors
Connect these outputs (MV OUT 1 and MV OUT 2) to video displays using HDMI cables.
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.
Note: Miranda’s NSH26M wiring terminal
adapter can be used to connect the GPI
and RS-422 lines to this connector.
The NSH26M comes with a label that
identifies the pinout to make wiring easy.
