Notes…
1.
The eight output HD-SDI distribution
amplifier (DA) is available with two levels of
monitoring
sophistication.
A
standard
option
which
provides
board
level
information such as supply faults and
minimum incoming signal analysis. The
enhanced
monitoring
option
adds
a
comprehensive incoming signal analysis
capability, including the detection of CRC
errors and identification of the line
standard/frame rate of the signal being
distributed. Refer to the monitor option code
on page 2 to identify what monitoring level
is fitted to the DA board.
2.
The interface card for the single channel
eight
output
DA
contains
ten
BNC
connectors
(see
following
page
for
drawing) of which only nine are actually
required for full operation (one IN, eight
OUT), the middle BNC not being used. A
dual channel version of the DA card is also
available (order number SHD_SDA2x S2)
which contains two separate four output
amplifiers. A dual channel DA also has a 10
BNC rear interface card (two lots of 1 IN,
four OUT). The only difference between the
rear interface cards for the two types of DA
is in the backpanel labelling. Mechanically
these two different types of rear interface
card are completely compatible with each
other and can be interchanged between the
different types of DA board. Refer to the
interface card option code on page 2 to
identify what interface card has been
supplied with the eight output DA main
board.
CAUTION:
Confusion
could
arise
if
single/double channel rear interface cards are
assigned to the wrong type of DA board.
Though full functionality will be maintained for
both types of DA, the difference in labelling
could be misleading if all such occurrences are
not fully documented at a system level.
