FRONT PANEL INDICATORS
The front panel of the SynPaQ/E contains four LEDs for status
display. Details are as follows:
PWR— This LED should always be GREEN when power is applied to
the SynPaQ/E.
TxD— The TxD indicator provides the user with visual feedback
concerning data output from the receiver. The TxD LED will
momentarily flash RED whenever the SynPaQ/E is sending GPS data
to the host.
RxD—
The RxD indicator will flash RED whenever commands are
received from the host computer.
1PPS— The 1PPS indicator will flash RED whenever a 1PPS pulse is
output from the GPS receiver. There are
2 Modes
of operation for the
1PPS flashing. In
Mode-1
the 1PPS will start to flash whether
satellites are being actively tracked and the receiver has developed a
position fix or not. In
Mode-2
the 1PPS will only flash if satellites are
being actively tracked and the receiver has developed a position fix.
The
Mode
is determined by the Receiver selected at time of
purchase. This indicator also serves as a “happy light”, giving the
user visual feedback that the receiver’s processor is powered up and
accomplishing normal housekeeping routines, unless the user has
previously disabled the
1PPS output through software control of the
receiver.
