      Notes…

1.

  The  dual  channel  HD-SDI  distribution

amplifier (DA) is available with two levels of
monitoring  sophistication. 

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.
