8 Video Transmit Unit with Ethernet

The AMG4781ER is a rackmount eight channel video transmit unit designed to transmit 8 video

signals and provide full duplex 100BaseT Ethernet connectivity over two singlemode fibres.

The AMG4781ER is designed to plug into an AMG2009 or AMG2015 subrack, which in turn fits into a

19" rack system.

The AMG4781ER is designed to operate with AMG4782E or rackmount equivalent AMG4782ER eight

channel video receive unit in a point to point configuration.

Introduction

Unit Functional Schematic

The AMG4781ER transmits up to 8 video

signals to the AMG4782E.

Ethernet connectivity is also provided

between the two units.

Optical Connection

The AMG4781ER is connected as illustrated below when used with an AMG4782ER 8-channel

receive unit acting as a point to point system.

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 both the Transmit unit and the Receive unit.

The Ethernet interface can operate at either 10Mbits/s half duplex, or 100Mbit/s full duplex, and data is

transmitted from one port the other port with the minimum of delay or buffering.

The 100BaseT port does not implement MDI/MDIX; it should be connected with a straight though

cable to an external switch port and with a cross over cable when connected directly to a PC or DTE.

Mounting Details

The unit is designed to be mounted within an AMG2009 or AMG2015 Subrack on standard card

guides.

Removal / replacement from / to the Case

Note: - The AMG unit PCB's are static sensitive. Handle with proper care and use normal electrostatic

discharge (ESD) procedures. Use properly grounded protection (for example, wrist straps) when

handling the PCB.

To remove units from the case to access the data expansion boards and the daughter boards, remove

the 2 or 4 fixing screws on the rear panel and slide the PCB's out of the case.

Ensure that the fibres do not snag or get trapped.

To replace the PCB's into the case, slide the PCB's gently into the case aligning the boards with the

appropriate slots. Ensure that the fibre do not snag or get trapped.

Safety

AMG Optical Fibre Products use Class 1 laser systems in accordance with EN 60825-2:2000.

It is always advisable to follow good practice when working with optical fibre systems. This includes:

Do not stare with unprotected eyes or with any unapproved collimating device at fibre

ends or connector faces, or point them at other people.

Use only approved filtered or attenuating viewing aids

For other safety issues and advice on good practice associated with optical fibre systems, please see

EN 60825-2:2000 or your local safety officer.
