DQI Behavior
Command Variable
When the calculation is converged to a PPP
service the DQI will report the value 2.
2
When the calculation is converged to a PPP
service the DQI will report the value 5.
5
The below command example shows the behaviour of the DQI when converged for PPP to a value of 2. The
highlighted area below is where the variable of
2
or
5
should be set:
GGAQUALITY 4 OUT_OF_BOUNDS 2 WAAS 2 PPP 2 PSRDIFF 2
4.6.8 Setting Baud rates via Terminal
The LD8 allows f or each Serial Port to be set at different baud rates. The f ollowing baud rates are available to
be set: 2400, 4800, 9600, 19200, 38400, 57600 (or) 115200.
To set the baud rate the SERIALCONFIG command should be used along with t he port name f or the desired
change. An example of the command is below, with the port and baud rate highlighted:
SERIALCONFIG COM1 9600 N 8 1 N OFF
4.6.9 Setting PPS via Terminal
The LD8 allows f or the PPS polarity to be configured and set to an increase in pulse f rom 0v (
POSITIVE
) or a
decrease in pulse to 0v (
NEGATIVE
). The pulse has a width of 2000 microseconds.
An example of the
PPSCONTROL
command is given below which shows the pulse being set to
positive
:
PPSCONTROL ENABLE POSITIVE
PPS output can be disabled by sending the following:
PPSCONTROL DISABLE
4.6.10 Enabling VERIPOS RTCM Output via Terminal
RTCM can be output on any of the LD8 serial COM ports. Within the terminal window enter the commands
below where updating COM1 with the desired output COM port number.
UNLOGALL COM1
INTERFACEMODE COM1 NONE RTCM OFF
LOG COM1 VERIPOSRAWRTCMDATAB ONNEW
To change the baud rate of the serial port, send command below. COM should be the same COM port as used
in the initial step and the field 9600 replaced with the appropriate baud rate.
SERIALCONFIG COM1 9600 N 8 1 N ON
