Flasher Hub - Configuration
Flasher Hub offers various configuration options. These determine Flasher Hub's behavior and can be used to enable, configure or disable different features.
Logging
This setting enables or disables Flasher Hub's log file.
Handshake interface
This setting enables or disables Flasher Hub's handshake interface. For more information on Flasher Hub's handshake interface, refer to Remote control.
Status port
This setting enables or disables Flasher Hub's Status Port. For more information on Flasher Hub's Status Port, refer to Status Port.
UART port
This setting enables or disables Flasher Hub's UART Port. For more information on Flasher Hub's UART Port, refer to UART Port.
Module position assignment
This setting determines how Flasher Hub assigns module positions. For more information on Flasher Hub's module position assignment, refer to Module configuration.
System time
This setting enables or disables Flasher Hub's system time.
Flasher Hub has no real-time clock (RTC) and no time reference.
The system time settings can be used to provide Flasher Hub with server to retrieve timestamps from, that will be used as time reference.
If available, the system time is used in Flasher Hub log messages and for file operations.
NTP server
Flasher Hub makes use of the network time protocol (NTP) to retrieve timestamps from a user-provided server.
An example of a publicly available NTP server is pool.ntp.org (hosted by the NTP pool project).
Time zone
Timestamps retrieved by an NTP server refer to the Coordinated Universal Time (UTC).
The time zone specifies an offset to UTC.
An example for a time zone is UTC+01:00, used for Central European Time (CET), among others.
Local clock
Local clocks are services in the local area network (LAN) that periodically broadcast their time into the LAN on UDP port 123. If the setting "Favor local clock, if available?" is set to Yes, such a local clock will be favored over the user-provided NTP server.
Current time
As a way to inspect if the saved NTP configuration works as expected, the current time is displayed.
Due to network latencies, it can take some time (usually up to a few seconds) for a valid NTP configuration to provide a timestamp for the first time.
