PC-AD2 - Installation 2
Fig 2-2: PC-AD2 Properties/Configuration Screen
For synchronising to another PC-AD2, connect a coaxial cable from SK1 on
the back of the master card to SK2 on the front of the slave card. Multiple
cards can be daisy-chained in this fashion, with each synchronised to the
preceding one.
At the bottom of the configuration page the PLL and AES input status is
shown. The PLL will indicate whether it is
locked
or
unlocked
and whether
its source is
internal
or
external
. When a sync source other than
None
is
selected, the source indicator will show
external
in green when it’s locked
to that source, or
internal
in orange if it’s unable to do so (typically because
the source sampling rate doesn’t match the card’s core sampling rate).
For each AES-3 input, the received sampling rate, frame lock and sampling
rate converter status is shown. If the displayed rate varies erratically or if
frame or converter lock can’t be achieved, check the cabling and make sure
the input isn’t doubly-terminated.
