below for
removal of the PCB

It is normal to set each AMG2700 insert unit to a different channel number. If a number is used twice
the second unit connected ‘down stream’ on the primary optical route will ‘over-write’ the first unit and
the video signal will be lost.
The channel number is only required to be set on SW1 on the primary channel TX card. Positions 1 to
3 on SW1 on the secondary channel TX card do not effect the operation of the equipment.
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
