Thanks, this worked beautifully and simply.
I can now synch a USB stick with the TSC7 (this makes the USB stick look like the TSC7 from the PC's Perspective)
Then Synch the USB to the PC, This gives the PC all the field updates and and loads new content onto the USB to send to the TSC7.
Then synch again with the USB/TSC7 and done.
By copying the data onto the usb stick then synching to the pc, the Trimble Business Center makes the device available to be assigned to Job sites/designs.
I will point out one trick i discovered. If you already have an SCS900 type controller that you have assigned to all your job sights and designs that you want this one to be associated with, you can copy and past the design files from the Trimble Synchronizer Data folder of that specific SCS900 device to the synchronizer folder of the TSC7 (or other device) and after synching that device will be assigned to all the same Job designs instead of manually going in and assigning it to every design one by one.
I figured out that trick after getting a rental TSC3 to and needed it to have all the same information as the TSC3 that needed repairs. It effectively cloned all the information. Business as usual.
