If the SMD uses SUB-RX and RX-SPLIT is on, the
•
newly selected path may collide with already built path
on the same SMD originating on the other RX port. In
this case, "OTHER RX - Take over? Y/N" is displayed.
If the user hits the "YES" button while the message is
displayed, the path originating at the other RX port will
be disconnected, and the path for the currently focused
RX port will be built.
Several other messages may be displayed, indicating
•
some sort of failure, e.g. "BOX [nr of module] - not
responding" when there is a bus fault (possibly
disconnected wire), or "SMD [nr of SMD] - is owner of
[nr of module]" when the setup is misconfigured (not all
elements of the setup configured from the same
configuration file).
Building a path (or even both RX and TX path, if TX split is off) may involve communication with many control
modules over the bus - especially with large installations - where multiple alternative antenna paths may be
available and might have to be tried to avoid conflicts between stations. Even though communication occurs at a
relatively high speed, in some instances this process may take as much as second or two. During this process
subsequent button presses are ignored until the path is completely built or it is rejected for any reason.
Selecting sub-selections
In some antenna paths, there
are points where the path can
be diverted to several sub-paths,
and a rapid control of these
points is desirable. Typically,
these are stacks and vertical
antenna arrays (such as four-
squares). These points have in
Router->Configuration
Management->RF Boxes-
>[module name]->Rules ticked
the checkboxes in the Include
to selection column; and then
its Description in the Antenna
Path tab is enclosed in square brackets.
When switching to such antenna path, sub-paths following the controlled point are selected quickly by pressing
buttons [1] to [4] (Front panel, pos.11-14), or their
combinations. The last subselection for every antenna
selection is remembered in the non-volatile memory of SMD.
When switching back to these antennas after switching away,
an attempt is made to build the same path and subselection. If
the selected subpath is not available (due to a conflict with
other existing paths), the first available subpath is selected
automatically, with no notification to the user, except the
indication of the currently selected subselection as described
below.
Assignment of a particular button/combination to individual subpaths (represented by respective inVectors) is
given by the table in Buttons subtab of controlling module's settings in Router.

In a non-split state (indicated by no dot and the LED above TX SPLIT button is not lit), a four-square
type antenna with name TFS-4 and label 4SQ is selected (as indicated by the displayed name and the
LED above button 2 lit). Sub-selection 2 is selected, as indicated by LED lit above button [2] and the
displayed azimuth according to the setting for this antenna selection in Router.

Requested selection is in conflict with the other Rx path of the
same SMD. Pressing YES button will disconnect the other RX
path and connect the requested path (here, focus is on RX1,
so the RX2 path is conflicting and can be disconnected)
Requested selection could not be completed because of an
error on the bus, a faulty module, or misconfiguration
A stack-type of path is selected, and state of sub-selections is
indicated by the combination of full (connected A-port) and
empty (not connected A-port) "boxes".
