CTEK Z45 Series User Manual

Z45X SERIES INDUSTRIAL CONTROLLERS - DECEMBER 23, 2020 23
Time and Location Source
The Time Source screen allows the user to select from one of three mechanisms to
synchronize the time reference on an individual Z4550 Controller.
Cellular Network
The controller retrieves and synchronizes to time provided by the cellular network
Network Time Protocol (NTP) Server
The controller retrieves and synchronizes to time provided by an NTP server. An IP
address field for the NTP server is provided on the screen.
GPS Location
The controller retrieves and synchronizes to time provided by the GPS or GLONASS
constellation. This option requires that GPS be enabled on the Location Source screen.
GPS functionality also requires that a GPS capable antenna be connected to the
secondary antenna connector in addition to the cellular antenna that is connected
the primary antenna connector.
Location Source
The Controller’s location source can be set to originate from the built-in GPS/GLONASS
receiver, or by using user defined coordinates. User defined coordinates are especially
useful for stationary installations that may not want to incur the expense of a GPS
antenna.
The Location Source screen also supports the creation of two geo-fences. Geo-fencing
applications are covered in detail in TechNote TN034.
SkyCloud Services
The SkyCloud Services screen serves two related purposes. It provides a method of
selecting a Dynamic Domain Name Service (DDNS) for the Z4550. Secondly, it is used to
configure the unit for operation on Ctek’s cloud based visual access and management
system, SkyCloud. See Technical Information Bulletin TIB006 for details.
