The distribution of clock signals within the Time 
Controller has lost synchronicity.  

If operating an ID900 Time Controller, please manually 
restart the Time Controller system.  

If using an external clock signal, and a manual system 
restart does not fix the error, try increasing the 

signal’s

 

pulse amplitude to TTL levels and/or adjusting the 
frequency closer to 10 MHz.
