Planning Your Videohub Installation
16
Universal Videohub Deck Control Cable has a single port at one end, for connection to both types of SDI
interface cards, and four RS-422 deck control ports at the other end.
The Universal Videohub 72 Crosspoint card contains the crosspoint processor for switching routes between
the SDI inputs and outputs, 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 the
Videohub is overheating due to inadequate cooling. A Power Overload light will illuminate on the card if
inadequate power is being supplied to the unit for the number of cards installed.
Occasional firmware updates can be downloaded from the Blackmagic Design website. Programmable
firmware can provide new features, compatibility with new hardware and support for new formats.
The Videohub firmware update utility runs on Mac OS X and Windows computers and uses a USB 2.0
connection to Universal Videohub 72. You will need to provide a USB 2.0 type A to mini B male cable.
Router Control Options
If router control is performed via Ethernet, the integrated “Videohub Server” is used and you need only
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. The Videohub Ethernet protocol, RS-422 protocol and RS-422 pinout diagram
are documented in the Developer Information section of this manual.
