OPERATING MODES 4
Changing the Run/Standby Modes
There are two methods you can follow to switch the receiver between the Run Mode
and the Standby Mode. Only one of these methods may be used at a time.
1. Using the XSTANDBY pin or
2. Using the serial ports under user control
Note – If you are using the XSTANDBY pin, do not use the serial ports for controlling
the modes. If you are using the serial port option, the XSTANDBY pin should always
be held high. You cannot use serial ports to switch to RUN mode if the XSTANDBY
pin was used to enter STANDBY mode.
Copernicus Standby Current
When the Copernicus GPS Receiver is sent a command to go into Standby Mode,
there is a period of time between 10 and 200 ms (milli seconds) when the power
supply still has to supply almost full operating current. Only after this period has
elapsed will the current draw go down to the specified standby current which is
typically 8.5 uA (micro Amps).
