MX 420 Installation and Service Manual
Press the up or down cursor key until the proper input port number is
selected.
The data that you will see on the screen is unprocessed. Therefore, if there are
errors in the data, you can compare the data against the NMEA 0183 standard.
You can also use this screen to verify that data is being received from external
RTCM sources or other equipment communicating with the MX420.
Dual Control (Remote) Interface
The Dual Control mode, which is enabled in the
CFG
Dual Contr.
screen, allows
you to connect two MX420s in a
Master / Slave
configuration where a common
database is shared between two MX420 control heads. This configuration also
allows you to use one antenna connected to the Master unit, for both MX420s. The
remaining data ports, the MOB /Event input port, and the alarm output ports are still
available on each unit for individual use on each MX420.
The hardware interface is accomplished by connecting NMEA Output 1 to NMEA
Input 1 between the two units.
