DISTRIBUTION
RRR----1
(Dashes ‘-‘ indicate
that these switches
are not related to
this function).
‘RRR’ are allowing control of distribution of one
or more input streams to one or more outputs.
000: 1=>1 2=>2 3=>3 4=>4
001: 1=>1 1=>2 3=>3 4=>4
010: 1=>1 1=>2 3=>3 3=>4
011: 1=>1 1=>2 1=>3 4=>4
1xx: 1=>1 1=>2 1=>3 1=>4
(Stream to output allocation)
‘000’ is factory
default.
See note below.
Input selection
---II--1
‘II’ are controlling which HD-input signal to
use.
00: Use optical input only
01: Use electrical input only
10: Auto, priority optical without lock control
11: Auto, priority optical with lock control
‘00’ is factory
default.
See note below.
Generator
Selection
-----OO1
‘OO’ are controlling which signal to use on the
outputs when no input signal exists.
00: Black picture, auto v.std.
01: Colour bar, auto v.std.
10: Black picture, 525 lines
11: Black picture, 625 lines
(auto v.std = automatic standard detection -
525/625 lines according to lost signal)
‘00’ is factory
default.
See note below.
Control Mode
-------D
‘D’ is controlling whether the board is
controlled by DIP-switches or from GYDA-SC.
0: GYDA-SC control
1: DIP-switch control
‘0’ is factory default.
Notes:
−
Be aware that it is possible to alter the swap or distribution on the MUX-side as well.
−
You may have to swap cables at the rear to get exactly the configuration you are
looking for
−
The ‘OO’ setting has no effect on outputs fed with a valid signal from the HD mux-
stream. It will only have effect when no input signal is present.
−
There is no on-board DVB-ASI signal generator available. When loosing a DVB-ASI
signal, the output will not carry a valid DVB-ASI signal.
On power-on, the actual settings will be according to the dip-switches, except when the
GYDA-SC control mode is selected. In that case, the last GYDA-SC setting will be restored
from on-board non-volatile memory.
In auto mode without lock control (ll=’10’), the operation is like this:
1.
If there is a carrier on the optical input, always select this input.
2.
If there is no carrier on the optical input, the electrical input will only be selected if it
has got a carrier.
3.
There is no check for signal lock and there are no significant delays before swapping
to the other input.
In auto mode with lock control (ll=’11’), the operation is like this:
1.
On power-on, the board will start with selecting the optical input as default.
