Setting up redundancy
The nTouch 180 redundancy system allows a standby unit to replace an active unit on the
network if it stops functioning.
When the system is used, the configuration settings from the active unit are automatically
copied to the standby unit to keep them synchronized. The two units are responsible for a
single role. There are two main modes of operation:
One nTouch 180 is the primary unit and a second nTouch 180 is the backup unit. The
primary unit is active and the backup unit is in standby mode. The backup unit
continuously monitors the primary unit and synchronizes its files with the primary unit. In
the event the primary unit fails, the backup unit will take over. If the primary unit starts
functioning, it will take over from the backup unit.
This mode is recommended when you want to prioritize the use of one unit over another.
The primary unit may have a serial device attached, for example, and you want this device
to be available to your project whenever possible. If a switchover is made to the backup
unit, but then the primary unit subsequently starts functioning, you want to switch back to
the primary unit immediately, so the serial device can be used.
Two nTouch 180 units are set up as peers. One unit is active and the other unit is in standby
mode. The unit in standby mode continuously monitors the active unit and synchronizes its
files with the active unit. In the event the active unit fails, the unit in standby mode will
take over. If the failed unit comes back online, it will run in standby mode and monitor the
active unit, ready to take over if there is another failure.
If Kiosk users are connected to a project hosted on an nTouch 180 unit when it fails, they will
be automatically connected to the project on the backup unit after a short delay.
Notes:
By default, when one nTouch 180 unit takes over from another, the controls in the project
(knobs, faders etc.) are reset to their default values. If you would like the controls to be set
to the most recent values displayed in Kiosk, you need to change a setting in NWare: On
the NWare File menu, click Project Properties, click Advanced, and then select the Auto
save settings check box.
It is important that you test the redundancy system carefully before using it in an
installation. If the switchover to the standby unit does not work, users will be unable to
connect to the NWare project.
You can set up a redundancy system to use an nControl unit and an nTouch 180 unit,
rather than units of the same type. However, the NWare project must be fully compatible
with both units, otherwise it will not function properly when the backup unit takes over.
To set up redundancy when using a primary unit and a backup unit
1. Power up both the nTouch 180 units.
