SYSTem:FACToryReset ONCE
SYSTem:CPURESET
SYSTem:ISP
3.9.1 SYSTem:COMMunicate:SERial:ECHO <ON|OFF>
This command enables/disables echo on RS-422/TTL SCPI serial port. This command has the
following format:
SYSTem:COMMunicate:SERial:ECHO <ON|OFF>
3.9.2 SYSTem:COMMunicate:SERial:PROmpt <ON|OFF>
This command enables/disables the prompt “scpi>” on the SCPI command lines. The prompt must be
enabled when used with the GPSCon utility discussed in
Chapter 5 . This command has the following
format:
SYSTem:COMMunicate:SERial:PROmpt <ON|OFF>
3.9.3 SYSTem:COMMunicate:SERial:BAUD
<9600|19200|38400|57600|115200>
This command sets the RS-422/TTL serial speed for SCPI serial port. The serial configuration is
always 8 bit, 1 stop bit, no parity, no HW flow control. Upon Factory reset, the speed is set at 115200
bauds. Higher baud rates such as 115200 are suggested if several NMEA commands are enabled, or
high rates of serial communications are expected to avoid serial port overflow. This command has the
following format:
SYSTem:COMMunicate:SERial:BAUD <9600|19200|38400|57600|115200>
3.9.4 SYSTem:STATus?
This query returns a full page of GNSS status in ASCII format. The output is compatible with the
GPSCon Windows program discussed in
Chapter 5 . The SYST:STAT? command is one of the most
useful single commands to query as it contains a wealth of information. This command is used by the
GPSCon application.
3.9.5 SYSTem:FACToryReset ONCE
This command applies the Factory Reset setting to the EEPROM. All aging, tempco, and user
parameters are overwritten with factory default values.
3.9.6 SYSTem:CPURESET
This command causes the Micro-JLT GNSS™ processor to reset.
