User's Manual
communication parameters are factory set to the following defaults: 115200 baud, 8 data
bit, 1 stop bit and no parity. This configuration may be changed by user to some other
appropriate combination. However, be aware that when target streaming is enabled the
radar sends out massive amounts of data that cannot be transferred with low baud rate.
Target streaming is automatically enabled by Configuration Utility during lane setup to
visualize target tracks. If/once the target streaming is disabled, the baud rate may be reset
to a lower value.
The RS232 interface is factory set to “cable detect” mode and will power the
RS232 driver chip down to save power if the radar RS232 RX (receive) line is not
connected. You need to connect both receive and transmit lines in order to
communicate with the radar.
The supplied Windows configuration program can automatically detect the baud
rate of the radar serial port.
High baud rate (115200 or 230400 baud) is required for lane setup via the
supplied Configuration Utility.
Connector Pinout
Note 1: See Appendix A for detailed description on how to hookup an external device to be triggered
when radar detects presence in a user configured lane. Incorrect hookup may result in the output driver
being destroyed and will not be covered under warranty.
Note 2: Trigger outputs 3, 4, 5 and 6 are only available in units manufactured after July 2011. These
units may be identified by serial numbers of 1107xxxx or greater where ‘xxxx’ digits are don’t care.
