Planning Your Videohub Installation
10
The Universal Videohub 288 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. 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. You will need a number 01 size Pozidriv
screwdriver to install the Universal Videohub 288 Crosspoint card.
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 288. 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 288 to your Ethernet network switch.
Third party router controllers can control Universal Videohub 288 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.
Power Supply Options
External power supplies connect to Universal Videohub 288 via power cards. Only one power card is needed
to power Universal Videohub 288 but two power cards should be installed if failover redundancy is required.
There are high and low power supply options for Universal Videohub 288. We strongly recommend the
high power supply to ensure sufficient power with all card combinations. The high power supply is named
the "Universal Videohub Power Supply". The low power supply may be considered due to its lower cost
but is slightly underpowered and will not power a fully populated Universal Videohub 288 under all card
combinations. The low power supply is a "Universal Videohub 450W Power Card"and requires three 150W
"brick" power supplies which are sold separately.
