Grass Valley Trinix v.2.4.1 - Manual (Page 21)

Planning and Installation Manual 21
The 128 x 128 chassis includes two fan modules; the 256 x 256 chassis
includes three, and the 512 x 512 includes six. Both power supplies and
fan modules are front loading and hot swappable.
Trinix Architecture
The architecture of the Trinix signal flow is organized into three cards:
input card, matrix card, and output card. These are connected to a
passive backplane circuit card. Each input and output card accommo-
dates 32 signals, which allows the routers to be built in increments of 32
as well a mixed population of SD and HD cards in increments of 32.
On switchers with HO-33110 HD and HO-33120 SD/HD output cards,
signal reclocking can be set to “Auto On/Off” or “Off” for each of the
32 outputs. In “Auto On/Off” mode, properly-formed standard data
rate signals will be reclocked but other signals will be bypassed (not
reclocked). “Standard” data rates are listed on page 79 .
The new VI-33100 “universal” input board auto-senses and accepts 16
composite analog SD, digital SD, or digital HD signals in any combina-
tion and passes them in digital SD or digital HD form (as appropriate)
to the Trinix matrix board. When analog signals are received, an exten-
sive set of gain, phase, filtering, and other adjustments are available for
each signal. For a list of these adjustments, see page 40 .
The BL-33000 Broadlinx option combines network interface, sync input,
and output monitor circuitry. Each card has two sync inputs and two
monitor outputs. Two cards can be installed for a total of four ports for
each. The sync reference supports generation of Vertical Interval Switch
Timing strobe from standard NTSC or PAL Black Burst or HDTV Tri-
level sync defined in the SMPTE 274M-1998 standard (see Glossary ).
Sync reference granularity is 32 outputs. An internal DIP switch is used
to select one of the available references for the respective 32-output
blocks. Trinix can also operate without a sync reference.
The Trinix fixed-frame routers all come standard as pre-wired single-
output units. The dual output option is implemented by adding phys-
ical expanders in increments of 16 up to 256. Both outputs are non-
inverting and fully meet DVB-ASI (see Glossary ) specifications.
Serviceability and Reliability
Trinix routing switchers are engineered by the same team that devel-
oped the Venus and Venus2001 family of routing switchers and use
many of the same proven circuit designs that made the Venus line the
best selling routers in the world. In addition, Trinix employs cutting-
edge technology to reduce the number of components, increase the reli-
