4 OPERATING MODES
Using the XSTANDBY Pin to Switch Modes
The first method for putting the receiver into Standby Mode or exiting this mode back
to the Run Mode is through the pin XSTANDBY, pin #16. As long as the pin is held
high, the receiver will operate normally in Run Mode.
Entering Standby Mode
When the pin is taken low, the receiver will go to the STANDBY mode.
Exiting Standby Mode
When the pin is taken high again, the receiver will perform a hot or warm restart and
return to normal operation. The receiver will hot start if the ephemeris is still valid.
Note – Excessive noise on the XSTANDBY pin could trigger the receiver to reset.
Using Serial Ports to Switch Modes
The second method for putting the receiver into Standby Mode is with TSIP packet
0xC0 or NMEA packet RT.
There are two possible conditions that would trigger the receiver to exit Standby
Mode and reset to normal operations:
1. Serial port activity
2. Exit after X elapsed seconds
