Login authentication

If you interface to the receivers using binary commands over serial communications, you may need login authentication. This is added to receiver models that run firmware version 3.30 or later. See Login.

If utilities such as the WinFlash utility or the Configuration ToolBox software do not work with the receivers running firmware version 3.30 or later, go to the Trimble website and then download the latest versions of these utilities. If your own application software no longer communicates with the receiver, contact Support for information about how to use the receiver in these cases.
