<password > ETHA
Note: If you are using a specific Network RTK system, certain NMEA strings are required to be sent
from the rover back to the RTK network. For example, if you are connected to the VRS mount
point, the rover is required to send its position to the network in a standard NMEA (National
Marine Electronics Association) GGA message. This can be achieved by issuing the following
command: LOG NCOMx GPGGA ONTIME 5, until data is received by the caster. For more
information about Network RTK options and properties, refer to our Application Note on
Network RTK for OEMV Receivers found on our website at
http://www.novatel.com/support/knowledge-and-learning/published-papers-and-
documents/application-notes/.
