Troubleshooting Masterclock Digital NTP Display

WinDiscovery uses bi-directional UDP messaging on port

6163 for both the discovery process and to communicate

configuration and status packets to and from the NTP

device(s). Delivery of UDP messages/packets is not

guaranteed. If you experience intermittent problems with

WinDiscovery, try closing the current session and restart

the application. If this does not resolve the issue try the

following trouble shooting tips, or switch to an alternate

method of configuration such as Telnet.

LOST PASSWORD

Possible reasons and solutions:

A password cannot be recovered if it is lost or forgotten.

Reset the Masterclock Display to the factory default

configuration using the procedure described in the section,

“Configuration”. Then the unit can be reconfigured and

provided with a new password. The default password will

once again be “public.”

UNABLE TO FIND/DISCOVER THE MASTERCLOCK

DISPLAY DEVICE USING WINDISCOVERY

Possible reasons and solutions:

 The discovery process was not complete before selecting

device(s). After clicking [Discover], wait until the status

indicates 100% completion.

 Verify that all network cables, hubs, etc. are in proper

working order. Be sure that Ethernet cross-over cables are

not being used where inappropriate.

 Verify that the network device is on the same physical

network as the computer from which you are running

WinDiscovery. If the computer is separated from the device

by a router or a firewall it is likely that the router/firewall is

blocking communication with the device. Run WinDiscovery

from a computer within the remote network, or ask a

network system administrator to configure the

router/firewall in question to pass through (both directions)

UDP broadcasts on port 6163. If this does not resolve the

detection problems you may additionally configure to pass

through both directions UDP broadcasts on ports 6165,

6166, and 6264.

 Verify that the hub/router/switch is capable of supporting

the 10mb speed that the attached network device requires.

 Verify that a DHCP/BOOTP server is present on the network.

If the device has been configured to use DHCP for network
