4.2. TriPad Operation
The TriPad is the receiver’s minimum interface used to display and control data input and output.
See the description of the TriPad on page 21.
To turn on/off the receiver, press the On/Off button (Figure ).
• When turning on, press the On/Off button until the TriPad’s LEDs briefly flash.
• When turning off, press the On/Off button until the LEDs go out, then release.
To start/stop logging data, press the FN button for 1–5 seconds (Figure ).
• During data recording, the REC LED is green. Use TriVU to set the recording time
interval. See “Recording Interval parameter” on page 61 for details.
• The REC LED blinks green each time data is written to the memory.
• If the REC LED is red, the receiver has run out of memory, has a hardware problem, or
contains an improper OAF (see “Option Authorization File (OAF)” on page 26 for more
information).
Use TriVU to enable the desired FN button mode in the receiver, either “LED blink mode switch”
for static measurings or “Occupation mode switch” for kinematic measurings. See “Data
Recording Auto-start parameter” on page 63 for details.
Each time you turn off or on data recording, either a new file opens or data appends to a particular
file. See “Always Append to the File parameter” on page 62 and “Files Creation Mode parameter”
on page 62 for information on setting these functions.
To toggle between post-processing modes, press the FN button for less than 1 second when
“Occupation mode switch” has been enabled using TriVU.
To change the information mode of the receiver, press the FN button for less than 1 second when
“LED blink mode switch” has been enabled using TriVU.
To change the baud rate of the receiver’s serial port, press the FN button for 5–8 seconds. This is
useful if the data collector does not support the rate that the receiver port is set to. After about five
seconds, the REC LED becomes red. Release the FN button during the next three seconds.
4.3. Static Measuring for Base Stations
Static measuring is the classic measuring method, well suited for all kinds of baselines (short,
medium, long). At least two receiver antennas, plumbed over measuring marks, simultaneously
collect raw data at each end of a baseline during a certain period of time. These two receivers
track four or more common satellites, have a common data logging rate (5–30 seconds), and the
