On the IQ-LINK front panel, connectics is as follows:
•
6 micro-USB cables for connection to the CAIRSENS (2) range sensors. The color code of cables is
as follows (see Figure 1–5 to view the (black/red/green/white) connection order :
Black Red Green
White
GND VDC D+
D-
•
Two ON and STATUS LEDs (1) to indicate the system operation status. Only one LED operates at
once: ON is blue, STATUS is green or red. The LEDs status are described below :
Both ON and STATUS LEDs are off AND the battery is correctly connected: the battery is completely
unloaded or the electronics malfunctions.
The ON LED is blue and flashes: the system operates autonomously via the battery and the solar
panels.
The ON LED is continuously blue: the system is supplied with direct current from the IQ-LINK mains
(8-30 VDC, 2A).
The STATUS LED is continuously red: the system has a power supply problem OR the battery is
almost unloaded.
Sending data to the cloud:
When sending data to the cloud, both these LEDS respect the next cycle:
1 – The ON LED is blue and flashes: the CAIRNET is powered on and operates properly.
2 – The ON LED turns off and the STATUS LED is green and flashes: wake-up (reactivation) of the
cellular communication system.
3 – The STATUS LED turns red and flashes: measurement recovery from the various sensors and
data sending preparation.
4 – The ON and STATUS LEDs turn off: connection to CAIRCLOUD and data sending.
5 – The ON LED turns again to flashing blue: the data sending cycle is completed, and the CAIRNET
operates normally.
