AMG3788BRN-DR-SF

Instruction Manual

8 Channel Video Receive Unit with up to 9 Bi-directional

Data and Audio Channels and Dual Redundant Operation -

includes AMG NMS Network Management Interface

The

AMG3788BRN-DR-SF

is a rackmount eight channel video receive unit designed to receive up to

8 video signals from a single fibre optical fibre ring with Dual Redundant operation. It also provides 9
bi-directional data/audio channels via a low speed data interface. Eight of the data/audio channel
interfaces, whether RS-232, RS-422, RS-485, 20mA, TTL, Contact Closure, Lonworks or Audio, are
defined at manufacture by the addition of daughter boards fitted onto the Data Expansion Board B.

The

AMG3788BRN-DR-SF

is designed to plug into an AMG2009 or AMG2015 subrack, which in turn

fits into a 19" rack system. It also includes an AMG Management Interface to allow Management of the
system using the AMG SNMP enabled Management software.

The

AMG3788BRN-DR-SF

is designed to operate with up to eight

AMG3713Bx-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

AMG3788BRN-DR-SF

may also be used with other

combinations of single, dual or four channel video and data insert units.
