## ECDIS Role Management

When the navigation bridge is powered on, there is no **Master** ECDIS on the network.

A notification about the absence of a **Master** ECDIS on the network will be displayed in the notification area:

The notification is displayed immediately after the navigation bridge is powered on, when no ECDIS has yet assumed the Master role.

The navigator can assign the **Master** role to any ECDIS that is part of the bridge, depending on operational necessity.

Subsequently, the **Master** role can be delegated to any other ECDIS as needed, or it can be requested by a **Backup** from the **Master**.

### Assigning the Master role

| Menu path |
|-------------|
| {{ menu }} → {{ settings }} → System → Workstations → Master Accept |
| or |
| {{ btn_backup_mode }} / {{ btn_master_mode }} → Workstations → Master Accept |

The ECDIS will send a network notification that this workstation has accepted the **Master** role.

A message will be displayed in the notification area:

The indicator button will display the role status {{ btn_master_mode }} **Master**.

### Transferring the Master role to a Backup

To transfer the **Master** role to a selected workstation:

| Menu path |
|-------------|
| {{ menu }} → {{ settings }} → System → Workstations → Select Backup → Transfer |
| or |
| {{ btn_backup_mode }} / {{ btn_master_mode }} → Workstations → Select Backup → Transfer |

The **Master** ECDIS role will be transferred to the selected workstation.

On the ECDIS from which the **Master** role was transferred, the role status in the permanent indication area will change from **Master** to {{ btn_backup_mode }} **Backup**.

In the workstation list, the workstation that received the **Master** role will display the new status.

On the ECDIS that received the **Master** role, the role status will change to {{ btn_master_mode }} **Master**.

### Requesting the Master role

When necessary, a **Backup** ECDIS can request the transfer of the **Master** role to itself:

| Menu path |
|-------------|
| {{ menu }} → {{ settings }} → System → Workstations → Master Request |
| or |
| {{ btn_backup_mode }} / {{ btn_master_mode }} → Workstations → Master Request |

The **Master** will display a request from the **Backup**.

To transfer the role, confirm the transfer on the **Master** by pressing the **Confirm** button.

The **Master** role will be transferred to the **Backup** ECDIS.
