Configuration
The SDI-TD-DMUX-4 is self-configuring in the sense that it will start working according to
default factory settings once the input signals and power are applied. Signals will be routed
straight through without swapping and SD-SDI/DVB-ASI will be detected and handled
automatically.
There are also configuration parameters available via DIP-switches in the front of the board
and via the Flashlink-protocol commands from GYDA-SC.
There are two variants of the boards. Early versions (boards with firmware revision (FW) 1.x)
have full flexibility channel swapping and no other configuration options. Later versions
(boards with firmware revision (FW) 2.0 and later) have more functions, but less flexibility on
channel swapping.
3.1
Newer boards (FW rev 2.0 and later)
The DIP switches control the channel-to-stream allocation according to the below table. See
also Figure 5 for details on setting the switches.
Note that when GYDA-SC mode is selected, there are no limitations on how the routing is
controlled – as opposed to when operating from DIP-switches.
Switch 1 (’off’ / 0)
Switch 2 (’off’ / 0)
Switch 3 (’off’ / 0)
Switch 4 (’off’ / 0)
Switch 5 (’off’ / 0)
Switch 6 (’off’ / 0)
Switch 7 (’off’ / 0)
Switch 8 (’off’ / 0)
