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 maximum

bandwidth (at 100Mbit/s full duplex) available for transmission across the fibre link is nominally

50MBit/s.

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.

Data and Audio Channel Configuration

The AMG4783BxE-SF and rackmount equivalent AMG4783BxER-SF sends and receives data

to/from Channel A and Channel B. Channel A is a single data interface selectable by the user with the

slide switch on the rear panel. Channel B carries a second channel of data / audio, the function and

physical interface being determined by the type of daughter board fitted to the B Channel data slot.

Note: (A) or (B) in brackets in above table refers to RS485 / RS422 data specification, not Channel A,

Data Channel A Configuration

Channel A is always present and allows for a RS232, RS422 (full duplex, four wire) or RS485 (half

duplex, two wire) interface depending on the position of the switch located above the RJ45 connector.

The switch signifies the presence of the X16004 Low Speed Data/Audio Interface Board. If there are

LED's present on the RJ45 connector then an X16003 Ethernet Interface Board is fitted.

The data input for both the RS485 and the RS422 modes detects a tri-state input condition by

monitoring the differential voltage level across the input. A differential level below 600mV positive or

negative will be detected as a tri-state condition. A level above 600mV positive or negative will be

detected as a logic 1 or logic zero respectively. It is important therefore to terminate the RS485 bus or

the RS422 input bus using 120Ω if a pre-bias is present on the RS485 or RS422 bus.

A large number of third party equipment manufacturers apply a pre-bias on their RS485 bus. This pre-

bias is applied by pulling one arm of the RS485 bus high (+5 volts) and the other arm low (0 volts)

using high value resistors within the third party equipment. In order to ensure that the AMG equipment

detects a tri-state condition, then these resistors should have a value above 5kΩ. If the third party

bias resistors are less the 750Ω the bus can be double or triple terminated as required to ensure that a

tri-state level is detected.

Note: The Data Channel A is shipped from the factory set up for RS485 operation unless otherwise

requested.

Mounting Details

The AMG unit is supplied with a clip-on mounting bracket which should be attached to a panel or wall

using 2 off 4.0mm screws, see diagram on page 1 for dimensions. The unit is clipped into the

mounting bracket, and is then held firmly in position.

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.

Maintenance and Repair

There are no user serviceable parts within AMG products. See unit data sheet for full specification.

In case of problem or failure, please call your local support centre or contact: AMG Systems Ltd. at
