Universal Videohub 72 Crosspoint Card
This module contains the crosspoint processor for switching video routes and changing deck control ports.
Ethernet, USB and serial ports are located on the card for router control.
A Reference input is located on the card for connection to a tri-level sync or blackburst genlock signal.
An Alarm light will illuminate on the card if user intervention is required, e.g., if inadequate cooling has
caused Videohub to overheat. Alarm notification is supplied by the GPI (General Purpose Interface) output
to other devices.
A Power Overload light will illuminate on the card if inadequate power is being supplied to the unit for the
number of cards installed.
Router Control Cable
Remote router control is performed via 10/100Base-T Ethernet or serial. If router control is performed via
Ethernet, the integrated Videohub Server is used. This means you only need to provide an Ethernet cable
to connect Universal Videohub 72 to your Ethernet network switch.
Third party router controllers can control Universal Videohub 72 via Ethernet, or as an RS-422 slave device, for
router crosspoint switching. Please refer to the Developer Information section of this manual for Videohub
and RS-422 protocols.
Power Supply
The Universal Videohub 450W Power Card provides connections for up to three 150W brick-style power
supplies, which must be purchased separately.
When fully populated and running at maximum power consumption, Universal Videohub 72 can be
powered by two 150W brick power supplies. A third power supply can be connected to ensure continued
operation should one power supply fail. The 150W power supplies are universal power supplies for use in all
countries. You will need to provide a standard IEC cord with a C13 connector for each power supply. When
fully populated with three power supplies, three mains power sockets will be required.
The high power supply designed for Universal Videohub 288 is ill-suited to Universal Videohub 72 because it
doesn't provide power redundancy to Universal Videohub 72, is more expensive and requires an additional
1 RU of space below Universal Videohub 72.
