You may raise the minimal speed factory setting of 5 km/h to e.g. 15 km/h to suppress slow
movements of vehicles, pedestrians or wind moved branches of trees, which may also initiate
measurements on short distance.
The „Maximal speed displayed“ is the highest measured speed value shown on the numeric
LED speed display. With the 2 ½ - digit LED display you may set the value between adjusted
minimal speed and a maximum of 199 km/h.
The reduction of the
Maximal speed displayed
to values just above a local speed limit (maybe
plus 20%) avoid the driver testing of the maximal shown speed or „tachometer checks“.
The setting of the
Maximal speed displayed
parameter is analogue the setting of the Minimal
speed displayed. The setting can be changed by the selection
5
in the
Settings
menu.
Both settings have no influence on the speed data storage and the output of serial data. All
speeds measured between 5 km/h and 199 km/h are stored, respectively transferred to a con-
nected computer terminal.
Hint:
By setting minimal and maximal speed displayed to equal values e. g. to 5
km/h, the vehicle speed data are memorized, resp. transferred to a connected termi-
nal, without an output on the numeric LED display for the vehicle drivers, see also
chapter 6.3.2.1.
6.3.4.3 Threshold blinking LED
Depending on the excess of the „Threshold blinking LED“ by the measured vehicle speed, the
numeric speed display is alternated for 0.25 seconds on and 0.25 seconds off time. In a display
update cycle with 1.5 seconds length the numeric speed „blinks“ up 3 times in short sequence.
This function can be used to reduce the power consumption of the system, with the effect of
nearly doubling the system operating time without battery recharge. Hereby the threshold value
is set to the minimum speed.
If the threshold is set to a local speed limit, this function can be used to point over speeding
drivers to their misbehavior, with the effect of a blinking (warning) display when the speed
limit is exceeded.
The threshold is set like the other thresholds in the range from 5 km/h till 200 km/h (blinking
deactivated).
6.3.4.4 Threshold LED mixed color (Option)
If the viasis is equipped with two LED colors, which can be shown at the same time and emit
seemingly a third color, the parameter “
Threshold LED mixed color
” is shown. Practically if
the viasis has e. g. green and red LED the result of displaying both colors is the mixture color
yellow, which is displayed if a measured vehicle speed exceeds the related, set threshold.
The speed threshold parameter is set similar to the speed threshold LED color change, see also
chapter 6.3.4.5.
For example if the viasis is equipped with yellow and red emitting LED the color sequence of
the display yellow – orange – red would be chosen with rising measured speed values, the
mixed LED color threshold (orange display) would be set to 31 km/h and the threshold LED
color change to 41 km/h.
Is the LED mixed color threshold set to a higher value than the LED color change threshold it
will have no visible effect on the display.
