D19m Technical Description
E42 D19m
Date printed:
30.06.20
LEDs: MADI OK Indicates that a valid MADI input signal is connected.
SYNC Indicates that the card is synchronized to the sync source.
CLIENT
Card is configured as
client
on the TDM bus.
SUPPLY Indicates “ power on” status.
Jumpers: SYNC MADI / AES Synchronization from MADI or AES/EBU.
CLIENT
If this jumper is inserted, the clock and the sync signals will be read from
the bus; otherwise, the MADI card writes the clock and the sync signals to
the bus.
