3.2.3. TX3000 Opto Synchronization
Setting rule
Since the TX3000 can be used as a synchronization master, repeater or slave, installations
can be flexibly configured. Basically there exists only one rule that has to be considered:
The optically transmitted synchronization signal may be repeated only once, therefore no
synchronization repeater should ever feed another repeater.
A basic configuration following this rule is shown below. The TX3000 board of level 1
(bi-opto version, configured as master) feeds the synchronization signal to the two
TX3000 boards of level 2 (bi-opto version, configured as slave). These two boards, acting
as synchronization repeaters, in turn each feed their optically transmitted signal to two
following TX3000 boards of level 3 (standard version, configured as slave). This way, a
synchronization cluster of 7 transmitters has been created without use of a master rack. If
a system consists of more than seven transmitters, a master rack has to be used as a
synchronization source.
