12 TRINIX — Release Notes
Version 3.2.0
Replacing Trinix Boards
When replacing Trinix boards, you should keep in mind that there was a
change in the VIT timing. This change was made to accommodate the addi
-
tional processing delay of 10.3 micro-seconds in the new 3G matrix cards.
The VIT signals generated from the NR and SR cards were advanced by
10.3 micro-seconds. All of the legacy matrix/output cards VIT timing will
be delayed by the same amount of time.
Grass Valley recommends that you use matched versions of boards (all
boards running Broadlinx version 3.X and newer) in your systems to meet
RP-168 switch points.
CAUTION Grass Valley strongly recommends that customers keep all software updated
to the latest released version. New boards are NOT guaranteed to be compat-
ible with older versions of software. A system failure may occur if a new
board is received as a replacement part and then loaded with an older version
of software.
However, a “mismatched” system will operate but with a minor timing
offset. If you mix a Broadlinx 3.x version board in a system that is running
Broadlinx 2.x, when switched, signals will be outside of the SMPTE RP-168
specification. In other words, the switch will occur as much as 10.3 micro-
seconds later (or early for 3.x NR/SR) for a path that passes through the
mismatched version board.
