ADAT connections 5-8 can be used as additional outputs for the connections 1-4, in order
to use them as simple ADAT splitter.
7. Settings
Prior to use, the configuration must be set by means of the DIP switches on the rear panel.
ADX-64: There are two DIP switch banks on the rear panel. Each bank sets the function for the
corresponding 32 channel submodule.
7.1. Input/output mode (DIP switches 1-4)
The transmission direction for the ADAT connections 1-4 are set with DIP switches 1-4:
Input: ADAT connection is configured as input. The received ADAT data is sent to the Cat5
cable.
The input signal is looped back to the corresponding output jack on the same
device ("local loopback"). This gives you the possibility to connect additional
monitoring, or to use the signal as wordclock source (see 9.2. Digital 24/8
multicore (sync over ADAT)).
Output: ADAT connection is configured as output. ADAT data will be received from the Cat5
cable and is forwarded to the optical output.
NOTE: For each ADAT connection, exactly one device on a bus must be set to "Input". All
others have to be set to "output" (only one signal source, but many signal sinks are allowed).
You can choose which of the devices acts as the sender ("Input") for each ADAT conection
independently.
7.2. Termination (DIP switches 5-8)
To avoid signal reflections which degrade signal quality, each end of the Cat5 cable has to be
terminated with matching resistors. These are integrated into the ADAT Multicore Extenders and can
be switched on by means of DIP switches 5-8.
On ADAT Multicore Extenders which are placed at the and of a Cat5 bus (that is, all devices
having
only one
Cat5 connector "A" or "B" plugged in), termination must be
switched on
.
On ADAT Multicore Extenders in the middle of a bus (that is, all devices where both
connectors "A" and "B" are used at the same time), termination must be
switched off.
NOTE: Switches 5,6,7,8 must all either be„ON“ or all „OFF“ stehen. Other combinations are not
