Video Switching
HDR44 Video Router Integration
The ATON HDR44 is a High Definition Video Router that provides the ability to view up to 4
different video sources in 4 separate areas (or 8 areas using an additional HDR44).
The HDR44 is dedicated to the first 4 sources and the first 4 zones of the AH66T. In a dual
AH66T system, one HDR44 is dedicated to the first chassis and the second HDR44 is
dedicated to the first 4 zones of the second AH66T.
Video Input # 1 of the HDR44 is “linked” to Audio Input # 1 of the AH66T; Video Input # 2
of the HDR44 is “linked” to Audio Input # 2 of the AH66T and so forth.
Video Output # 1 of HDR44 # 1 is dedicated to Zone # 1 of the AH66T; Video Output # 2 of
HDR44 # 1 is dedicated to Zone # 2 of the AH66T and so forth.
Video Output # 1 of HDR44 # 2 is dedicated to Zone # 7 of the AH66T; Video Output # 2 of
HDR44 # 2 is dedicated to Zone # 8 of the AH66T and so forth.
Note: Zones 5 and 6 of the first AH66T and zones 11 and 12 of the second AH66t will not
have a video feed.
Install the HDR44 and connect the ATON R44WP wall plates as described in the HDR44
manual. For this application, the HDR44 audio and source IR connections are NOT used.
Using the ATON R44IRM remote, verify correct video switching.
Connect one of the IR ALL Ports of the MAIN AH66T chassis to the EXTERNAL IR INPUT of
the MAIN HDR44. If two HDR44s are being used, connect the ALL OUT port of the first
HDR44 to the EXTERNAL IR IN of the second chassis.
For dual HDR44 systems, be sure to set the unit IDs correctly for each chassis. See the
HDR44 application notes at www.atonhome.com.
The diagram on the next page shows a dual AH66T system with dual HDR44s.
For clarity, only the IR connection from the AH66T to the HDR44s, the A-Net connection
and the video loop connections for sources one and two are shown.
