D19m MADO – MADI Out for Coaxial Cable
1.940.520
The “MADO” MADI output card serves as multiplexer in a D19m rack.
The TDM bus data, written by analog or digital input cards to the bus, are
read and output as a MADI signal. The channel allocation can be selected
by the control software.
The card is synchronized by the sync input and distributes the clock signals
required for the TDM bus. Four additional AES/EBU sync outputs are
available. If the external sync signal is invalid, the internal generator is
automatically activated and generates a sync signal. Since the frequency ac-
curacy is ±1 ppm and an AES/EBU signal is output as sync signal, this can
be used for the synchronization of a studio.
The MADO cards can be controlled by RS485 from an external device. The
frame address is set by a DIP switch on the backplane.
