Instruction Manual

4 Channel Video Transmit Unit with up to 8 Bi-directional

Data and Audio Channels for a Singlemode Single Fibre

Link

The AMG4747AG-SF is a rackmount four channel video transmit unit designed to transmit 4 video

signals and transmit and receive up to 8 data or audio signals over one Singlemode fibre. The 8

data/audio channel interfaces, whether RS232, RS422, RS485, 20mA, TTL, Contact Closure,

Lonworks or Audio, are defined at manufacture by the addition of daughter boards fitted onto the Data

Expansion Board A.

The AMG4747AG-SF is designed to plug into an AMG2009 or AMG2015 subrack, which in turn fits

into a 19" rack system.

The AMG4747AG-SF is designed to operate with AMG4748A-SF or rackmount equivalent

AMG4748AG-SF four channel video receive unit in a point to point configuration.

Data and Audio Channel Configuration

The AMG4748A-SF and rackmount equivalent AMG4748AG-SF sends and receives data in one bank

- Bank A. Bank B is not used. The physical interface is determined by the fitting of AMG data or audio

daughter boards onto the appropriate data expansion board slots.

Data Interface Daughter Board Options

The data interface daughter board options are as follows:

Option Code

'x'

Part No.

Description

0 X12542 4 Wire Audio Interface Daughter Board

1 X04057 RS422/485 Data Interface Daughter Board

2 X04049 RS232 Data Interface Daughter Board

4 X12579 TTL Data Interface Daughter Board

5 X12578 Contact Closure Data Interface Daughter Board

6 X13038 FTT10A Echelon Lonworks Data Interface Daughter Board

Data and Audio Channel Configuration

The data expansion board slots are accessed by removing the AMG unit from its case. A data channel

is active when a daughter board is installed in the required data channel slot. Each data interface

board enables one bi-directional channel.

Daughter Board Layout

The channel slots are as follows:

Data and Audio Daughter Board Fitting Instruction

The data and audio daughter boards pushed on to the pin headers mounted on the data expansion

boards. Ensure that the connectors are lined up correctly and not offset before pushing firmly in place.

Note that the data and audio channel numbers are associated with each slot. This allocates the pin

numbers on the rear panel connector together with the front panel LED indicators.

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
