Configuration
Variable Name
Description
ST
Target detection sensitivity. Valid values are from 10 to 100 and are a
percentage of max magnitude. This value should be left at 100, unless
the radar is over counting due to mounting location.
MO
Radar mode bitmask. Bits are as follows:
Bit 0: SI3 ASCII command compat flag. Contact us for more details.
Bit 1: Enable ASCII console output on RS232 serial port
Bit 2 to 15: Currently reserved in DC310 radar
MD
Radar mode bitmask number 2. Bits are as follows:
Bit 0: Enable low voltage power down. See Appendix C for details.
Bit 1: Enable True Average Speed output
Bit 2: Force enable the RS232 interface when set. Sets to “cable detect”
mode when bit is cleared. Power usage is increased by 0.012Watts if
this interface is force enabled or if RS232 cable is connected.
Bit 3: Reserved in DC310 radar
Bit 4: Save traffic statistics (if enabled in radar) in 3mph/5kph speed
bins rather than original default of 5mph/10kph speed bins
Bit 5: Enable beeper (For armadillo)
Bit 6: Enable cycle skipping mode to save power when no vehicles are
detected
HT
Output Hold Time in milliseconds. Once the output is triggered, it is
held for this amount of seconds from the last trigger source before
going inactive.
IO
Radar IO configuration bitmask. Bits are as follows:
Bit 0: Reserved in DC310 radar
Bit 1: Active high open drain 1 output
Bit 2 to 8: Reserved in DC310 radar
Bit 9: Active high open drain 2 output
Bit 10 to 15: Reserved in DC310 radar
