6.3 The main board
There are also a number of connectors on the board itself. None of these are intended for the
end-user. For proper operation, make sure there is a jumper in the lower position of the
connector located behind the DIP-switches (see Figure 12 and Figure 13 below).
The rear end of the boards (with the connector that mates to the backplane) is towards the
right side of the board. The boards must be mounted in a Flashlink FR-2RU-10-2 frame with
dedicated backplanes. Avoid inserting the SDI-TD-MUX-4 or SDI-TD-DMUX-4 board into a
wrong backplane, as this may cause electrical and/or mechanical damage to the main
boards and/or the backplanes.
