View source for FCDC-3 - Backwards compatibility

The [[FCDC-3]] is '''fully compatible''' with [[FCDC-1]], [[FCDC-2]] (including [[:Category:Stations#Turbine_stations|TFIX stations]] and [https://exigo.zenitel.com/wiki/Category:Ex_Access_Panels Exigo Ex Access Panels]) after these devices have been [[Flowire Software Upgrade Procedure|upgraded]] to '''software version 4.1.3.13''' or newer.
* If these devices are running version '''4.1.3.12 or older''', there will be no compatibility. There will be no connection between the FCDC-3 and these devices.
* In mixed cluster, FCDC1/2 should be set as "Not CCo". One FCDC3 should be set as "CCo" . For that reason we recommend to replace the rack side Flowires with FCDC3 when FCDC1/2 need to be replaced.

If you mix software version 4.1.3.12 (or older) and version 4.1.3.13 (or newer) on the same Flowire network, there will be limited compatibility. They will connect and let you do software upgrade, but regular operations will not work.

{{Note|'''Note on [[:Category:Stations#Turbine_stations|TFIX station]]''':
* ''Upgrading or downgrading of TFIX-stations '''must''' be done by using a FCDC1 or FCDC2''
* ''If a TFIX-station is replaced with a new station, read software version of the new station and upgrade/downgrade software if needed:''
** ''If connected to FCDC2: The FCDC2 and the TFIX-station needs to run the same version''
** ''If connected to FCDC3: TFIX-station needs to run version 4.1.3.13 (or newer)''
