LEDs

iMetos3.3 has a set of 6 LEDs deployed in two rows: the upper row gives information about the modem, the lower row gives information about the processor and the communication process (see Picture).

When the battery is plugged to the connector D (see Picture 1) all three LEDs in the lower row turn on for an instant. After this the GPRS connection with FieldClimate starts and the LEDs give information about the different stages of this process.

 

Important note:

Complete monitoring of the communication process should be done after every installation by connecting the PC to the iMetos. This is described in detail in section USB communication with PC.

 

Upper row: Modem (from left to right):

  • Green LED (left) : on, during the connection process to the GSM  network, blinking slowly (short on and long off) when is connected to the GSM network
  • Yellow LED (center): modem is on and ready for communication
  • Red LED (right): this LED is currently not used

 

Lower row: Processor (from left to right):

  • Green LED (left): USB cable is plugged (except when in boot mode – i.e. the boot jumper I is plugged on BOOT pins)
  • Yellow LED (center): indicates one of the following:

1.      in boot mode (plugged jumper I, see Picture 6): Pessl bootloader is installed

2.      in terminal mode (plugged jumper F, see picture 6) the meaning of the LED is given on the screen of the terminal program in the PC

3.      in normal/scheduling mode (without any jumpers) :

a)      if the modem is on: modem blink code:

i.      short on – long off: waiting for modem, network found, SIM card is active

on――――on――――on――――on――――on――――on――――on――――on――――on――――on

ii.    short on – short on – long off: connected to GSM

on-on――――on-on――――on-on――――on-on――――on-on――――on-on――――on-on

iii.   short on – short on – short on – long off: connected to FieldClimate

on-on-on――――on-on-on――――on-on-on――――on-on-on――――on-on-on――――on-on-on

iv.   short on – short on – short on – short on – long off: data has been sent and commands from the server have been received.

on-on-on-on――――on-on-on-on――――on-on-on-on――――on-on-on-on――――on-on-on-on

 

b)      if the modem is off: the measurement process is in progress, it will light a few seconds every 5 minutes.

 

Clue:

Put all the attention in the center LED of the second row if you see the sequence of four blinks then you will know that the upload has been successful, if the sequence is not completed the red LED aside will light the take note of the last blinking mode before to identify the error.

·      

Red LED(right):

1.      communication error (if modem is on)

2.      serious system error (if modem is off)

In both cases you will need to connect the iMetos3.3 to the PC and use PI Firmware uploader to make the diagnostic and extract useful information to send to support@metos.at
