Network connection
Video Grabber has two RJ45 ports, named LAN 1 and LAN 2. When both interfaces are configured and
active (connected) then the same data is sent through both of them. This way two independent
systems can receive the same data from the Video Grabber using two physically separate connections
thus achieving redundancy.
Device can work in 10, 100 and 1000 Mbit/s network, however when higher framerates and resolutions
are in use 1000 Mbit/s network may be required to comply with higher data rates. Video Grabber
detects type of network automatically as long as network connection cable complies with network
standard CAT5e

or higher.

Power supply unit
Figure 7: Connecting power to the Video Grabber
Connecting Video Grabber to power source:
1.
Plug power supply unit to Video Grabber, make sure *click* is heard.
2.
Tighten the screw on the plug to secure power supply unit from unplugging.
3.
Power supply unit can now be connected to power source.
Video Grabber has two power inputs (PWR1 and PWR2), but requires only one power supply to work
properly. The dual power input design gives user an option of ensuring power redundancy for the
device which may be required in some systems (e.g. ATC related). When two power supplies are used
then Video Grabber balances the load on both of them. If one of them fails then Video Grabber will
continue working by using remaining power supply exclusively.
Video Grabber uses 12V, 2.5A power supply, but its maximum power consumption is 12W.

The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These
documents specify performance characteristics and test requirements for frequencies up to 100 MHz. Cable
types, connector types and cabling topologies are defined by TIA/EIA-568-B. Nearly always, 8P8C modular
connectors (often referred to as RJ45 connectors) are used for connecting category 5 cable. The cable is
terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be
mixed in an installation so long as the same scheme is used on both ends of each cable.
