commands, or log data.
USING CDU
CDU provides access to key information about your receiver and
its position. The information is displayed in windows accessed
from the View menu. For example, select Position Window from
the View menu to display the position solution of the receiver. To
show details of the GNSS and geostationary (SBAS) satellites
being tracked, select a Tracking Status Window (GPS or
GLONASS) from the View menu. Select Help from the main
menu for more details on CDU, its windows and features.
DETERMINING WHEN THE POSITION IS VALID
When the receiver has a valid position, the Solution Status field
in CDU’s Position window shows Computed.
ENTERING COMMANDS
The OEMV family receivers use a comprehensive command
interface. Commands can be sent to the FlexPak using the
Console window in CDU, which is opened from the View menu.
Enter commands in the text box at the bottom of the Console
window.
The following information is important when entering commands:
• Commands can be entered in three formats:
• ASCII (log bestposa)
• Abbreviated ASCII (log bestpos)
• Binary (log bestposb).
Abbreviated ASCII is the best format to use when you
wish to work with the receiver directly. For data
collection, use ASCII or Binary.
• Press the Enter key to send the command string to the
receiver.
• The commands are not case sensitive.
The OEMV Family Quick Reference Guide provided with the
receiver lists the available commands and the parameters they
use for the Abbreviated ASCII format.
