B.5 RADARCFG Configure the ER Output

Use this command to configure the Emulated Radar (ER) output. ER is available through the AG-Star
Communication/Power cable, see Table 7, AG-Star Communication/Power Cable Pinouts on page 48 for pin-
out details.
Message ID: 8192
Syntax
radarcfg switch freq_step update_rate resp_mode threshold
Field Data
1 RADARCFG This field contains the command name or the message
header header depending on whether the command is abbreviated
ASCII, ASCII or binary.
2 switch Enable or disable radar emulation
(default = enable)
3 freq_step Frequency step per kilometer per hour (Hz/kph).
Range: 26.11, 28.12 or 36.11
(default = 26.11)
4 update_rate Specify how often to update radar output (in Hz)
Range: 1, 2, 5, 10, 20
(default = 10)
5 resp_mode Specify the time, response mode, over which to average
velocity samples, see Table 13, Response Modes on
page 57.
(Default = 500)
6 threshold The threshold is only applicable when the response mode is
set to 2. The response time is 1000 ms when the velocity is
greater than this value, otherwise, it is 500 ms.
Range: 2-50 kph
(default = 5 kph)
a. 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 2000ms, the number of samples used will be 10.
Example 1 to disable radar emulation:
Example 2 to set the frequency step to 36.11 Hz/kph,
update rate to 1 Hz and no smoothing:
