Input/Output Control: 20-pin Connector
Remember to configure
the DVMHD’s inputs for
Voltage or Contact
Closure. If you do not,
the inputs will not be
damaged, but they may
not operate correctly.
This setting can be
configured using the
front-panel or via Serial
or Ethernet command.
A wiring harness that
mates to this
connector is included
with the DVMHD.
The Input/Output Control connector provides 8 configurable inputs, and 2 dry contact
relay outputs. The inputs are software configurable for either Voltage or Contact
Closure operation. The behavior of these inputs is also software configurable. The
outputs are primarily used to indicate when the DVMHD is in either the Playing or
Error state, although this functionality can be changed in software as well.
For more information on how to use this connector to control the DVMHD, please
refer to the Input/Output Control section of this manual.
