9 Online mode
9.1 Introduction to Online mode
Online mode is a mode that allows changes to be made to the configuration of a live
system without the need to download a new configuration. The new configuration is held in
the matrix and even if the matrix is reset the modified configuration is preserved rather
than defaulting back to the original configuration map.
The changes are not automatically added to the system configuration controlled by EHX
until the modified configuration is saved either by clicking on the Save’ button in the File
menu on exiting Online mode, by downloading a map to the matrix or by exiting EHX and
selecting Yes to save the configuration.
Online mode allows:
• The labels on a key (including beltpacks) to be added, deleted or moved in Panel
Programming.
• Forced Listen and Blocked Listens to be updated in Local Advanced.
The functions which can be used in Online mode are indicated by green color-coding of
the menu entries and button text.
However there is an important limitation when using Online mode on linked systems. If a
label refers to a source or destination on a remote matrix (a matrix linked to the current
matrix) it cannot be assigned in Online mode unless it is already present in the current
map being modified. In order for such a label to be present in a configuration it must have
been assigned at least once and then downloaded as part of a map.
In this way it is recognized by the matrix if it is assigned in Online mode. Local sources
and destinations (on the current matrix) can be assigned for the first time in Online mode
provided they have already been set up in the current map. For example a local Party Line
cannot be created in Online mode but it can be assigned to a key for the first time in
Online mode.
If a remote source or destination is assigned to a key for the first time in Online mode the
label is initially displayed in the panel mimic and then disappear because the matrix rejects
the assignment request. Further information on this limitation is given later in this chapter.
Online mode operates in a completely live mode so that as soon as a change is made in
EHX the configuration in the matrix is updated. If a label on a key is changed for example,
the panel affected is updated without any further user intervention.
EHX is notified of any changes that are made online, as a consequence of this, if EHX
running on any other PC which is also configuring the same matrix and in Online mode it is
also updated with the changes. Therefore it is possible for more than one EHX to be
editing a configuration with each change being displayed on all the copies of EHX
connected and in Online mode. However this mode of operation is not recommended due
to the risk of the different copies of the configuration diverging later if one of the instances
of EHX ceases to be online.
