Trimble 4D ControlTM Software, version 4.5.1
This software update for Trimble® 4D Control™ contains all changes since the release of version 4.5.0. The following document gives you an overview of the changes.

Data Collector 

The Data Collector module offers the category Round Scheduler to enable the scheduling function for round measurements and to configure its settings.

•	Run Time

The configured start time of scheduled rounds refers to UTC time. A huge difference between UTC time and local time could result in missing rounds at the beginning or the end of a selected day. With this software update the time-related settings work as expected.
Note: Please verify and re-apply settings at the configuration dialog of the round scheduler after applying the software update.  
•	Repeat Interval 
The scheduler configuration allows to specifying after which time the round is repeated in case a target could not be measured. The repeat action does not apply any longer to rounds that were started manually. 

Trimble 4D Web 

Since the release of Trimble 4D Control version 4.5 the Maps page allows to uploading images that are not geo-referenced. The manual specification of its extents at Trimble 4D Web has been reworked and is more robust now.
