To Check the Signal Quality of your iMETOS 3.3 with the Terminal Program you need:
- Jumper (Jumper RM2,54)
- USB to Mini USB cable
- Station where you want to check the Signal quality
- Battery from the station
- PI Service Terminal program
Link for PI Service Terminal download:

For more information or help please read Download PI Service Terminal in our solutions.
Please follow these instructions:
Make sure there is !! NO JUMPER on the motherboard !!
Connect the PC and the motherboard (PCB) with the USB cable.
Start the PI Service terminal program.
Connect the battery at the station (LEDs start to flash).
On "Serial port" select the correct COM used (1) see image below.
The Baud rate is set automatically (2) see image below.
Then click "Connect" (3) see image below.
To see the Signal Quality
Put jumper on J1 at PCB
and go to
(1) MODEM SETTINGS - Modem is now turning on
Wait until Modem process is finished and
(4) SIGNAL QUALITY GRAPH
The Signal Quality Graph above is interpreted following:
RSSI is the Quatlity of the Signal (from 0-31)
RSSI: 31 = perfect Quality of the Signal
RSSI: 30-7 = Quality of the Signal is okay
RSSI : 6 and lower = bad Signal (no good condition for communication)
BER means how often data packets have to be retransmitted - so 0 is the best
BER: 99 = not known or not detectable (this is no error just an information)
So the Example of Signal Quality Graph shown above is totaly okay.
When the Signal Quality Graph shows >No signal detected < please search for an other location with better Signal for your station.
To Check the Signal Quality of your iMETOS 3.3 with Field Climate you need:
- Field Climate Access
Go to Device Settings and then to Information.
In the red square you see the Signal strength in % - so 100% is best and 0% is the worst.
In this special case with 3% of Signal strength i would recommend to search for another location for the station with better Signal Quality
