Application Scenarios
Sync the time of terminal players.
Related Information
Time synchronization is to synchronize the time of terminal players. Users can choose NTP or Lora for time synchronization according to actual condition.
- NTP: Synchronize the time of terminal players according to NTP server. No hardware is needed. But the accuracy of time synchronization depends on the Internet speed and data will be needed if you use 4G network for time synchronization.
- Lora: Used by Taurus. It is required to set master and slave devices. The time of slave device is synchronized with the master device (reference device) via Lora network. According to actual needs, the time of master device can be synchronized via NTP server. It is needed to buy Lora devices. This is suitable for scenarios highly demanding time synchronization. No data will be needed. But the signal reception depends on environment and is limited by distance.
System administrator can view all the time synchronization tasks. Sub-users can view the tasks only in the public workgroup, the workgroup the sub-user belongs to and its sub-workgroups, as well as the tasks shared to the workgroup the sub-user belongs to.
Step 1 Choose 
> Players Management > Time Synchronization.
Step 2 View all the time synchronization tasks created by the current user, or view a task by searching its name.
Step 3 (Optional) Select filter criteria in the Filter on the left side of the page to quickly filter out required time synchronization tasks. If you want to save the settings, select Remember filter criteria.
Step 4 (Optional) Click a time synchronous task name in the Name column to enter the attribute page of the task.
Step 1 Choose > Players Management > Time Synchronization.
Step 2 (Optional) Click NTP server configuration to configure the information of NTP server and then click Save&Close.
The attributes of public servers (China, America) cannot be modified. The attributes including basic info and workgroup of NTP servers added by the user can be modified.
Step 3 On the Time Synchronization tab page, click New.
Step 4 Enter a name for the task, choose time synchronization mode and then click Next.
- NTP: Choose NTP server and click OK.
- LORA: Choose a reference device for time synchronization and click OK. Lora mode is only valid for asynchronous players.
Step 1 Choose > Players Management > Time Synchronization.
Step 2 Select a time synchronization task and click Attribute, or click a task name. Time synchronization task attributes are explained in Table 3-13.
Table 3-13 Time synchronization task attributes
Tab Name | Description |
|---|---|
Basic Info | Set the name and description of the time synchronization task. |
Workgroups | Set the workgroup the time synchronization task belongs to. |
Configure |
|
Players | Add or delete the players contained in the time synchronization task. |
Step 3 After the attributes are edited, click Save or Save&Close.
Step 1 Choose > Players Management > Time Synchronization.
Step 2 Select one or more time synchronization tasks and click Delete.
Step 3 Click OK in the pop-up dialog box.
