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 10.3us in the new 3G matrix cards.
The VIT signals generated from the NR and SR cards were advanced by
10.3us. All of the legacy matrix/output cards VIT timing will be delayed by
a similar amount.
Grass Valley recommends that you operate with matched versions of
boards to meet RP-168 switch points. However, the system will operate but
with a minor timing offset.
If you mix a Broadlinx 3.x version board in a system that is running Broad-
linx 2.x, when switched, signals will be outside of the SMPTE RP-168 spec-
ification. In other words, the switch will occur as much as 10.3us later (or
early for 3.x NR/SR) for a path that passes through the mismatched version
board.
