RS activation and visual indications
Turn on the RS unit by pressing the on/off pushbutton (6) using a pin
(paper clip or similar).
The RS has one red LED indicator that can be seen from the two viewing
/ vent holes on the side and back panel (marked as element #2). This
indicator blinks as defined in Table 5
Table 5: RS LED indications
LED Indicator
Description
1 sec single blink
Activation visual feedback. Pressing the internal pushbutton for three
seconds (use a pin), while the R-Sensor is not active, will cause the R-
sensor to go active and to display a single blink of one second
Flashing red
Network connectivity indication: Pressing the pushbutton for at least
one second, will cause the LED indicator to show the connectivity sate
of the R-Sensor. A one second repetitive blink means the R-Sensor is
NOT part of a sensor network and measurements are logged in the
sensor's memory
Constant red
Network connectivity indication: Pressing the pushbutton, for at least
one second, will cause the LED indicator to show the connectivity sate
of the R-Sensor. A constant on LED light means the R-sensor is part of
a sensor network and measurements are delivered to the U-sensor
gateway

U-Sensor Gateway
The U-Sensor Gateway is designed to transmit all the data collected by
CartaSense sensors throughout the monitored site to the communication
server and through it – to the Web application.
The USG acts as an access point for U-sensors, R-Sensors, M-sensors and
other CartaSense wireless sensors. The USG is the "root node" of the sensors
network, where all measurements are uploaded to. The USG also connects to
the communication server, further uploading measurements from the sensors
through an internet connection, whether cellular or LAN based.
Several versions of USGs are available. – The USGs differ in their system
interface and include the following:
Cellular GPRS interface.
GPRS cellular with GPS location module.
Dashboard mounted GPS/GPRS unit
Ethernet 10/100 MB interface
