AMG4787AR-DR-SF

Instruction Manual

8 Channel Video Receive Unit with 8 Bi-directional Data and

Audio Channels plus Dual Redundant Operation

The AMG4788AR-DR-SF is a rackmount eight channel video receive unit designed to receive 8 video signals and transmit and receive up to 8 data or audio signals over two Singlemode fibres with Dual

Redundant operation. 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 AMG4788AR-DR-SF is designed to plug into an AMG2009 or AMG2015 subrack, which in turn fits into a 19" rack system.

The AMG4788AR-DR-SF is designed to operate with AMG4787A-DR-SF or rackmount equivalent

AMG4787AR-DR-SF eight channel video transmit unit in a point to point configuration.

Introduction

Unit Functional Schematic

The AMG4788AR-DR-SF receives up to 8 video and 8 data signals from the

AMG4787A-DR-SF .

It also transmits 8 data signals to the AMG4787A-DR-SF .

The AMG4787A-DR-SF transmits and receives the optical signals from both primary and secondary optical channels. These optical channels are transmitted on the same optical fibre in opposite directions, operating at different wavelengths. The primary channel operates on 1550nm and the secondary channel on 1310nm.

The AMG4787A-DR-SF receives and drops off a data signal transmitted from an AMG4788A-DR-SF receiver. It then inserts video and a data signal onto the outgoing optical signal. In normal operation the video and data signals are transmitted on the primary output and the data received from the primary input. The secondary optical input is independent and is regenerated on the secondary output.

At the AMG4788A-DR-SF receiver if the primary input signal is not present, the unit will shut down the secondary output to inform the AMG4787A-DR-SF that the primary signal route is not OK. The

AMG4787A-DR-SF will then send out the video and data signals on its secondary output in the opposite direction. As the primary input at the AMG4788A-DR-SF is not present the data signal will now be taken from the secondary optical input, thus maintaining integrity of the data transmission.

Optical Connection

The AMG4788AR-DR-SF is connected as illustrated below when used with an AMG4787A-DR-SF 8channel transmit unit acting as a point to point system.

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.

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:
