To check the GLONASS option you will need to have installed the Topcon software PCCDU which is available at the bottom of this article.

When you have installed the PCCDU software you can check the GLONASS option by following the steps below.

Note: If LD2 does not have Port3 switch on rear panel connect 9 way D Serial Cable to P5 and set P5 to Remote in Configuration- Serial Ports on the LD2.

Click on the PCCDU icon and select the PC COM port you are using.
