For any kind of True Tracking Backup configuration within the grandMA family there is no need to join consoles
of the same type or DMX channel count together. The grandMA software is most flexible and will correct
possible difference in the actual hardware for you.

The master console always demands the slave(s) to behave like the master hardware. This means a big
grandMA master forces a grandMA light slave to be a big grandMA temporarily as well which results in
phantom executor faders and buttons as the grandMA light (or grandMA replay unit) only has a reduced
hardware. Switching executor pages will then renumber the executors as given by the first executor on the
master console.
When the connection is either manually or automatically (by a user-definable timeout) broken the slave
console can be switched to solo mode with maintaining the setup and configuration of the lost master. For
example, a grandMA master connected to a grandMA light slave will force the light to operate like a grandMA,
even when the connection is lost and the grandMA light is forced to solo mode.
The table shows what master/slave connections are possible and how many and which executor faders and
buttons are available on the slave during Tracking Backup and in solo mode afterwards.
Please note that the slaves assignment of executor faders and buttons restores to the hardware default after the
console is once re-booted.

In a True Tracking Backup system the DMX channel count of the master console demands a temporary update
or downgrade of the connected grandMA slave automatically. If a 4096 channel master is connected to a 2048
channel slave the grandMA slave will take over the 4096 channels and process them in all conditions even
when the back connection is broken nevertheless what original channel count is installed.
Rebooting the slave will restore the installed channel count immediately. In a True Tracking Backup situation
where the master is defective this may cause a loss of show data as only DMX channels 1 to 2048 are processed
on smaller 2048 channel systems. Therefore please make sure that the channel upgrade is being implemented
on the slave.

Though the grandMA Offline Editor software cannot be used to actively control DMX-channels as the ArtNet
protocol is permanently disabled it still can be used in a master/slave connection with real grandMA consoles.
Because of the limitations of the PC hardware in combination with Windows® operation systems the grandMA
Offline Editor must be seen as weakest part of the EtherNet chain therefore it may only be operated as master
console.
You may use this setup with a PC as master to easily transfer show file data to other grandMA consoles
(whatever type they are), especially when they are used on a distributed network.
