Getting Acquainted

TriPad

1.2.1. TriPad
The TriPad is the receiver's minimum interface used to display and control data input and output.
The STAT (Status) LED displays the number of tracked satellites.
• When the receiver is on and no satellites are tracked, the STAT LED will blink red.
• When satellites are tracked, the STAT LED will produce one blink for each tracked satellite (green
for GPS, orange for GLONASS).
The On/Off (power) button turns the receiver on and off.
Pressing the FN button for less than one second switches the receiver between different information
modes (normal and extended information), or between static and dynamic post-processing modes,
depending on the receiver's configuration.
• During the first second of pressing the FN button, the REC LED is orange.
• Pressing the FN button for more than one and less than five seconds will start/stop data recording.
• During data recording the REC LED is green or orange.
• 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 16 for more information on
OAFs).
• The REC LED blinks green or orange each time data is written to the internal receiver's memory.
• 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 36 and "Files Creation Mode parameter"
on page 36 for information on setting this function.
• Pressing the FN button for more than five and less than eight seconds will turn the baud rate of
serial port A to 9600. After about five seconds of pressing the FN button, the REC LED becomes
red. Release the FN button while the REC LED is red (during the next three seconds).
• Pressing the FN button for more than eight seconds has no impact.
After loading new firmware or clearing the receiver's NVRAM, the receiver checks its internal file
system. During this operation, the REC LED flashes orange, and the file system is not accessible for
CDU (control display unit) applications or for data recording. This operation may require from fractions
of a second to several minutes, depending on the circumstances and the amount of internal memory.
