Universal Videohub 72
What you need to get started
Universal Videohub 72 is a medium-sized modular router ideal for growing facilities. It features
an 18 card rack frame that can be filled with any combination of BNC SDI or optical fiber
SDI interface cards. When fully populated with a crosspoint card, a power card, 18 SDI interface
cards and 18 deck control cables, Universal Videohub 72 provides 72 SDI inputs,
72 SDI outputs, 72 bidirectional RS-422 deck control ports, reference input, redundant power
supply options and powerful Videohub routing control software for Mac and Windows.
Occasionally, the internal software of the Universal Videohub 72 will need to be updated.
Videohub Setup will prompt you if an update is required. The utility uses the USB 2.0
connection and you will need to provide a USB 2.0 type A to mini B male cable.
Universal Videohub 72 ships as an empty rack frame, except for a removable fan tray and fans.
All other hardware components, including SDI interface cards, deck control cables, crosspoint
card and power supplies must be purchased and installed separately. SDI interface cards can
be purchased as your facility grows and don’t need to be installed all at once. This section is
designed to help you decide which components you will need before you build your Universal
Videohub 72.
See the ‘SDI Interface Card’ and ‘Universal Videohub Interface Cards’ sections for more
information on the different interface cards available for your Universal Videohub.
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 black burst
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.
