It is normal to set each AMG2700 insert units to a different optical channel numbers. If an optical
channel is used twice the second unit connected ‘down stream’ on the optical route will ‘over-write’ the
first unit and the video signal from the first unit will be lost.
The units are set to channel 1 at the factory – the channels should be set prior to installation
SW1 Switch Settings
Only switch positions 1 to 3 should be set by the user, all other switch settings are set at the factory as

Removal From the Case
Note: -
The 2700 PCB’s are static sensitive. Handle with proper care and use normal electrostatic
discharge (ESD) procedures. Use properly grounded protection (for example, wrist stamps) when
handling the PCB.
In order to remove the case (to access SW1 and SW2)
1.1. Loosen and remove the two screws on the top and bottom of the unit’s rear panel.
1.2. Slide the PCB assembly connected to the rear panel out of the case.
1.3. Ensure that the optical fibre is not trapped.
(in order to access SW1 and SW2 it is only necessary to slide out the PCB by 25mm. This has
the advantage of ensuring the ensuring the fibre does not trap and the PCB remains protected
form any EMC damage.)
