3.2 Supply schedule and equipment
To the delivery containment of our systems belong following components:
1. Viasis speed measurement and display system for vehicle speeding
2. Fuses, 2 pieces (one spare piece)
3. Sliding nuts M6, 4 pieces for standard C-profile rails
4. Serial interface cable, about 4 meters long
5. CDROM with manual, terminal and data evaluation software
6. Option USB – USB cable and USB flash storage stick
Measured and stored data from a viasis can be read with a personal computer, a notebook or
laptop with serial RS232 interface and the delivered viagraph software working with Windows
XP/Vista/7/8 and Windows 10.
If you want to use the serial RS232 interface of the viasis, but your computer offers only a
USB interface, you can obtain a serial USB-RS232 adapter from us, see annex chapter 10.1 –
list of viasis equipment.
4 System description
The viasis 3003 measures and displays vehicle speeds of one drive lane and direction. The
viasis is an accumulator supplied, mobile measurement system, particularly designed for lowest
power consumption. Measured speeds are shown on a 300 mm high, seven-segment LED
board with 2 ½ digits. The used high brightness LED are mounted behind a rigid “phantom
light” mask to avoid seemingly display of speeds due to sun or vehicle light reflection.
Alternating with the numeric speed display, several warning and speed limit sign symbols with
a circle diameter of 300 mm can be shown. Optionally the viasis 3003 is equipped with two
LED display colors, with the possibility to change the displayed color according the compari-
son result of measured vehicle speed and a set speed threshold.
Measured vehicle speeds are stored in the viasis, marked with time and date of the measure-
ment and can be later transferred by means of a serial communication interface like RS232,
USB or other optional radio data interfaces, like Bluetooth or GSM/GPRS mobile phone. The
viasis can be set to measure data of both driving directions of a two lane road and to store the
data for later evaluation.
Typically the viasis measures periodically every 1.5 seconds and shows the result. In case of a
new vehicle measurement the display is refreshed after 1.5 seconds, otherwise the display is
hold for maximal 3 seconds.
The measuring unit consists of a continuous wave „Doppler Radar“, a permanent sending high
frequency radio wave emitting and receiving unit, whose antenna is not visible through the
front window pane. This measuring unit delivers the received signals by an amplifier and digital
processing electronic to a microprocessor unit that evaluates the signals.
The viasis 3003 is delivered with numerous options, see also chapter 6.3.6, in several variants
like viasis COMPACT, MINI, PLUS, PLUS SMILE, etc. for various different applications.
