Notes…
1.
The dual channel 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 signals 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 dual channel DA
contains ten BNC connectors of which all
ten are actually required for full operation
(two lots of one IN and four OUT). A single
channel eight output version of the DA card
is also available (order number SHD_SDA1-
SX) which provides eight outputs from a
signal input signal. A single channel DA
also has a 10 BNC rear interface card but
only nine BNC connectors are required
(one IN, eight 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 dual
channel 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.
