Whitelisting Requirements for the TBC Update Service

If you run check for updates and it fails to connect or times out on its connection to the Updater Service, it is quite possible that your IT department needs to unblock ports and whitelist Trimble.com so that the updater can work. The ports that need to be available include

· Port 80 (http://dl.trimble.com)

· Port 443 (https://updates.t-iserv.com)

Hope that this helps
