Problem: Colons are flashing for several seconds when I apply new configuration settings under
WinDiscovery or Telnet.
Problem: Colons are flashing for several seconds at random times.
Possible Reasons/solutions:
1. This is also normal behavior each time new configuration settings are downloaded to the clock
and saved using either WinDiscovery or Telnet.. During this time, the network clock will
receive the new configuration settings and save them to its flash memory. The network clock
then re-initializes (soft restart) and continues operation with the new settings. The only time to
be concerned is if the colons do not stop flashing after several seconds.
2. This can occur if multiple users are using WinDiscovery/Telnet or both on the network,
simultaneously. Verify that you are the only current user of WinDiscovery or Telnet, and/or that
only you can administer , and/or that you have password protection enabled.
3. This is also normal behavior when the clock cannot reach the primary or secondary NTP time
server during queries or the broadcast timeout has been exceeded. If the "Advanced Settings"
have been altered, you may return them to there default values. See "Advanced Settings"
section of WinDiscovery.
Problem: Clock display is frozen and is blank, has strange characters, or the time is not incrementing.
Possible Reasons/solutions:
1. The clock display may have been set using the User Control mode. Disable the user control
mode and restore the clock to normal operation mode.
Problem: When using the serial port interface for configuration, during initial power up or after a reset
the clock announces its IP address as: "My IP address is 0.0.0.0 ".
Possible Reasons/solutions:
1. This is normal operation. The clock has not yet configured or been assigned its IP address under
DHCP mode prior to announcing or making available its serial interface user menu. You can
reveal the IP address by refreshing the menu and announcement. To reveal the IP address, first
enter the password. Select the exit option "X" from the menu. The initial clock announcement
and the menu will re-fresh and the actual IP address will be displayed if known.
Problem:
You have lost your password.
Possible reasons/solutions:
1. The password cannot be recovered if it is lost. Reset the clock to the factory default
configuration using the procedure described in the Configuration section. After the clock has
been reset to factory defaults, the unit must be reconfigured. The default password is "public"
Problem:
Multiple error windows titled "Bad Password" continue to pop-up each time a configuration setting is
applied.
