CHAPTER 15 Configuration In this chapter: Q Configuring the receiver in real time Q Configuring the receiver using application files Q Application files 15 The Trimble R6 GPS and R8 GNSS receivers have no controls to change settings. To configure the receiver, use external software such as GPS Configurator, WinFlash, or Trimble Survey Controller. There are two ways to configure the receiver.
15 15.1 Configuration Configuring the receiver in real time GPS Configurator and Trimble Survey Controller software support real-time configuration of the receiver. When you configure the receiver in real time, you use one of these software applications to specify which settings you want to change. When you apply the changes, the receiver settings change immediately. Any changes that you apply to the receiver are reflected in the current application file, which is always present in the receiver.
Configuration 15 An application file does not have to contain all of these records. When you apply an application file, any option that is not included in the records in the file remains at its current setting. For example, if you apply an application file that only specifies the elevation mask to use, all other settings remain as they were before the application file was applied. You can store up to twenty different application files in the receiver.
15 Configuration Power up application file The power up application file (Power_up.cfg) is used to set the receiver to a specific configuration any time the unit is powered up. In this file, you can specify that the receiver is reset to defaults before the power up settings are applied. This ensures that restarting the receiver always resets it to factory defaults prior to applying the power up application file.
Configuration Naming application files The application filename in the office computer and in the receiver are always the same. This makes it easier to recognize and keep track of your application files. When you change the name of the application file in the receiver, this changes the application filename on your computer. When you transfer an application file from the receiver and save it to the computer, the system renames the file to match the internal receiver file.
