RADARCONFIG

Configure the Emulated Radar Output

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

Use this command to configure the Emulated Radar (ER) output.

The ER signal is output on the VARF or EVENT_OUT1 pin of the receiver.

When RADARCONFIG is enabled, the BESTVELTYPE command mode is set to DOPPLER.

Message ID: 1878

Abbreviated ASCII Syntax:

RADARCONFIG switch [freq_step [update_rate [resp_mode [threshold]]]]

Factory Default:

radarconfig disable

ASCII Example:

radarconfig enable 26.11 5hz 2 3.5

Field	Field Type	ASCII Value	Binary Value	Description	Format	Binary Bytes	Binary Offset
1	Command header	-	-	RADARCONFIG header This field contains the command name for abbreviated ASCII or the message header for ASCII (see page 1) or Binary (see page 1).	-	H	0
2	switch	DISABLE	0	Disables radar emulation	Enum	4	H
		ENABLE	1	Enables radar emulation
3	freq_step	10.06 16.32 26.11 28.12 34.80 36.11		Frequency step per kilometre per hour. (default = 36.11 Hz/kph)	Double	8	H+4
4	update_rate	1HZ	1	Rate at which the output frequency is adjusted (default = 10HZ)1 The number of samples used for smoothing depends on both the update_rate and resp_mode parameters. For instance, if the update_rate is 5 Hz and the resp_mode is 2000 ms, the number of samples used will be 10.	Enum	4	H+12
		2HZ	2
		5HZ	3
		10HZ	4
		20HZ	5
5	resp_mode	See Table: Response Modes		Specify how responsive radar emulation is to changes in velocity (Default = 500)1	Integer	4	H+16
6	threshold	2 to 50 kph		The speed threshold at which to switch between response mode 1000 and response mode 500. The threshold is only applicable when the response mode is set to 2. (default = 5 kph)	Double	8	H+20

Response Modes

Mode	Description
1	Immediate. This results in the lowest latency at the cost of higher noise.
2	Automatically switch between 1000 and 500 depending on speed. When speed is below the Threshold parameter, use Response Mode 500. Otherwise, use Response Mode 1000.
500	Signal is minimally smoothed resulting in low latency but increased noise.
1000	Output signal is smoothed over a smaller window resulting in less latency than 2000 and less noise than 500.
2000	Output signal is smoothed to reduce noise at the cost of higher latency.
