SYSTEM HARDWARE OVERVIEW
RS422 SERIAL INTERFACE
A UART interface is provided that uses RS422 voltage levels on the communications connector. The default baud
rate for this interface is 115200. This however maybe changed using the *BAUD command to speeds of up to
926000. The *BAUD command must be followed by a *PUS command to store the new value to non-volatile
memory. This new value will be used next time the radar reboots.
The serial interface default setup during normal operation is shown in table below.
The RS422 provides the primary output of the radar in the form of ASCII messages.
The communications connector is a Bulgin PXO412/08P connector, mating type PX0410/08S/6065.
The pin out of the connector is shown in the table below.
TEMPERATURE SENSOR
A temperature sensor has been installed in the radar. The temperature of the radar may be requested using the
*TEMP command.
