Back End

The majority of the backend equipment is located at 'Node 0' and housed in a standard 22U 19" rack.

 From top to bottom of the rack:

The top Sky Digibox is dedicated to Radio channels and is controlled by the IR flasher stuck on the front. This is driven through Homeseer via USBUIRT.

The second Sky didbox is the Multiroom box and is sent through the house via the Kramer Matrix below.

Next up is the SKY HD box. This is connected by HDMI and Optical sound to the Home Cinema receiver and by component and stereo audio to the Matrix for distrubtion through the house. As I found the SKY HD box runs hot. I've fitted a 1U fan blade below to help cooling which has done the trick.





The Russound controller is a 6 zone (with 4 sub zones) whole house audio controller. Each room (zone) has a keypad on the wall to provide direct control. It's also controlled through Mainlobby.  I also use 2 of the ABUS sub zones to feed the master ensuite and the garage.

Underneath is the Kramer Audio/Video matrix. The audio is daisy chained through the Russound.

Although the Matrix is designed for RGBHV video it has more than enough bandwidth to cope with 1080i component video. I've also used one of the SYNC channels to switch digital audio although I'm not using this yet.

The matrix can be switched by either Mainlobby or IR commands from the universal remote controls in each room.



Below the matrix is a Popcorn hour media player and a Sony Blu ray player.

Both are distributed through the Matrix and have a direct (HDMI) connection to the home cinema receiver.

Control is via IR from each room universal remote via the IR distribution over Coax.

And doesn't the flash show up the dust :-0


The bottom of the rack it taken up with the 3 servers and the UPS.

The larger 4 U server is the main automation server which is custom built. This server has multiple USB ports and 10 Serial ports to cope with the RS232 devices.

Next down is the dedicated Geovision server providing high quality CCTV coverage, including motion detection etc.

Below that is the RDP server, dedicated to providing the host for the Airpanel displays. This runs a hacked version of Win XP pro that allows 2 concurrent connections.

All 3 servers are built in a short rack case from Evercase.co.uk as the rack is not deep enough for standard size server cases.

At the very bottom is a 2U APC UPS to protect the servers and the core network devices (Router, Switch etc)
