9. road the violator limit may be set to 26 mph and the low and high cutoffs will be set 15 mph below and above this value respectively The exact values are of course left to the judgment of the user No other action is required The PNL10 will display the measured speed when an incoming vehicle is detected between the low speed and high speed limits The display will blink at about 1 4Hz rate if the measured speed is above violator speed This indicates to the driver that they are driving above the speed limit If the white LED cluster is populated this is the default you may chose to have it removed and enabled through the software configuration it will strobe at a 10Hz rate The strobe can also be configured to blink at 1 4 Hz rate when activated Finally if the vehicle speed is above the high speed display cutoff the display will be blanked This prevents drivers from racing against the sign trying to see how high a speed they can display The strobe may be configured to stay active or go blank above this speed As long as the radar is tracking a target between the low speed cutoff and the high speed cutoff the radar will transmit the speed in user selected ASCII format over the serial interface This may be observed via our PC based configuration tool or captured by an external user provided controller board Monitoring or capturing this speed is not required for normal operation of the speed sign Serial output is affected
