Data Receive Unit with up to 8 Bi
-
directional Data and
Audio Channels plus Ethernet
The
AMG4708AE
is a standalone data receive unit designed to transmit and receive up to 8 data or
audio signals plus full duplex 10
0BaseT Ethernet connectivity over two singlemode fibres. 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
Exp
ansion Board A.
The
AMG4708AE
is designed to be powered by an
AMG2003
power supply.
The
AMG4708AE
is designed to operate with
AMG4707AE
or rackmount equivalent
AMG4707AEG
data transmit unit in a point to point configuration.

Data and Audio Channel Configuration
The
AMG4708AE
and rackmount equivalent
AMG4708AEG
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 a
ppropriate data expansion board slots.
Data Interface Daughter Board Options

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 dat
a 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 expa
nsion
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 w
ith the front panel LED indicators.

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. 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 electrost
atic
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 pa
nel 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 se
e
EN 60825
-
2:2000 or your local safety officer.
