If the Trinix router is set to be used with an Encore control system, the INT
XPT CNTL switch must be set to closed. The Secondary columns will auto-
matically be shown as 1-based, as opposed to zero-based if he Trinix router
is used with a Jupiter control system.
There is no “follow” level locking function when the routing switcher is
controlled by Encore; in other words, it remains possible to inadvertently
perform a breakaway switch.
Single Matrix Router Controlled by Encore
On a system cold start, the status is pulled into the RCE from the matrix
(because it is the most likely to reflect the actual status of the crosspoints).
In other scenarios, where the RCE is known to have good status (That is,
when a backup matrix controller is inserted into a matrix with an already
active primary controller, or when a single matrix controller is removed
and replaced), the MAP can be pushed down into the matrix.
The scenarios below should be considered when using a single matrix con-
troller:
1. Replacing a single NR board, with a cleared map, into a running
system:
• The RCE MAP is pushed down to the new NR board because the
system detected the board going off-line and then back on-line (the
system knows that the RCE MAP is current and can be pushed
down to the matrix controller.
This should work the same with a dirty map.
