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

 

If the device has been configured to use DHCP 

for network configuration but no DHCP/BOOTP server is 
present, the device may not respond to discovery 
requests for up to twenty seconds after power-on. 
DHCP configuration is enabled as a factory-default. In 
addition, the device will reset its fallback address to one 
within the link-local address space 

“169.254.xxx.xxx”

 

when no DHCP server is present or is not able to be 
reached.

 

Reset the device to initiate a new DHCP IP 

address request, or use static IP address mode. Consult 
your network system administrator to ensure that a 
DHCP server is present and accessible on your network 
and/or to obtain a list/range of available IP addresses.  

 

CLOCK DOES NOT RESPOND TO CONFIGURATION 
CHANGES AND/OR STATUS DISPLAY IS 
INTERMITTENT 

 

 

Device was found using WinDiscovery, but the status 
display is intermittent or not updating and/or the clock 
does not appear to be responding to configuration 
changes under the current WinDiscovery session.  

 

Clock(s) previously found during a recent session of 
WinDiscovery do not show up during the current 
session.  

 

The clock status or settings displayed under 
WinDiscovery

 

show garbled characters.  

 

Possible reasons and solutions:  

1.   The WinDiscovery application has been open for too 

long and the clock configuration(s) have changed. For 
example, this can occur if the DHCP server has issued a 
new/refreshed address. Close the WinDiscovery 
application and restart.  

2.   The discovery process was not complete before 

selecting began. After clicking [

Discover

], wait until the 

discovery status indicates 100% completion.  

3.   Verify that the physical network cables and equipment 

are configured for UDP.  

4.   Verify that you are currently the only user accessing the 

device via WinDiscovery or Telnet.  

5.   The network may currently be experiencing heavy 

traffic which is reducing bandwidth and/or causing 
collisions with the UDP packets between the device(s) 
and WinDiscovery. Since delivery of UDP messages are 
not guaranteed, this can cause WinDiscovery to not 
receive the latest configuration or status packets and 
thus show outdated or garbled information. 

6.   In some cases, the device may not be discovered and 

displayed in the WinDiscovery device tree. In others, 
previously discovered devices may no longer be
