Rear view
The rear view of the board is towards the right side of the board, as shown in Figure 3. The
board must be mounted in a Flashlink FR-2RU-10-2 frame with a dedicated backplane board
for the SDI-TD-DMUX-4 board.
Figure 4 shows the backplane rear view. Avoid inserting the SDI-TD-DMUX-4 board into a
wrong backplane board, as this may cause electrical or mechanical damage to the board.
The SD1 to SD4 outputs are for 270 Mbps SD-SDI or DVB-ASI signals.
The HD input carries the electrical HD signal with the four input signals time division
multiplexed according to the SMPTE 346M-2000 standard.
The optical input is the same as the HD-input, but with an optical interface.
The GPI outputs are alarm signals for driving external alarm devices.

Note that the same backplane can be used for both the SDI-TD-MUX-4 board and the SDI-
TD-DMUX-4 board.
The following connectors are available:
Name Description

Note: There are also a number of connectors on the board itself, but none of these are
usable to 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 3).
