8 Channel Video Receive Unit with 2 Bi-directional Data and
Audio Channels plus Ethernet for a Dual Redundant
The AMG3684BxE-DR-SF is a standalone eight channel video receive unit designed to receive up to
8 video signals from a single fibre multimode optical fibre ring with Dual Redundant operation. It also
provides 2 bi-directional data/audio channels via a low speed data interface plus full duplex 100BaseT
Ethernet connectivity around the ring.
The AMG3684BxE-DR-SF is designed to be powered using an AMG2003 standalone power supply.
The AMG3684BxE-DR-SF is designed to operate with up to eight AMG3613BxE-DR-SF single
channel video insert units. Each receiver will 'drop off' up to eight video channels which are being
transmitted around the fibre ring. The AMG3684BxE-DR-SF may also be used with other
combinations of single, dual or four channel video and data insert units.

Page 9: Ethernet Operation
Ethernet Operation In order for the AMG system to transmit Ethernet signals, an onboard RJ45 Ethernet interface or X16003 Ethernet interface adaptor should be fitted to all units in the ring. The Ethernet interface can operate at either 10Mbits/s half duplex, or 100Mbit/s full duplex. When all the Ethernet interfaces around the ring are operating at 100Mbit/s full duplex the system behaves as a multi-port repeater. -
