Connecting to the iDR-4(8)
You can connect
either or both expanders according to the requirements of your
application. The
iDR-in
AUDIO OUT connects to the
iDR-4(8)
AUDIO IN. The
iDR-out
AUDIO IN connects to the
iDR-4(8)
AUDIO OUT. Ensure that the expander DR-Link IN connects to
DR-Link on the
iDR-4(8)
it is associated with. If both
expanders are used with the same
iDR-4(8)
then daisy chain
from DR-Link OUT on one to DR-Link IN on the other. DR-Link
can also be daisy chained from or to
iDR-switch
units if you
are using them as well.
Fully expanded iDR-4(8)
The diagram below shows
the
iDR-8
with both the input and output expanders fitted.
Note the connection of DR-Link which is daisy chained from
one unit to the next. If an
iDR-switch
unit is also fitted then
daisy chain DR-Link from the last expander to the switch box.
Make sure you plug into the correct DR-Link socket.
Use CAT5 STP cable. A pair of standard 2 metre cables is
provided with each expander. Maximum cable length is 250
metres. This means that the expander units can be used for
remote audio over CAT5 cable.
