Hello folks,
I am a newbie with this modem. Is a great piece, and I have 4 running up to now. I use it to m2m, in order to receive data collected remotelly in 4 sites. That would be 20 quickly, but we shall understand it better before.
In 2 of them, we just have it working nicely out of box, simply removed from the box and seted up via our data logger (an Ammonit 40M), and it works nicelly, connecting 3 times a day and sending all data wished.
Strangely, 2 of them are not OK. It was configured in the exactly same way of the other 2, that are ok, but these two have some problems about keep the signal strong and connect. When we remove the power supply, ans re-insert, it it shows signal in 41% (even using an external anten) and later logger displays 15%, and finally ¨unknow¨.
It send some data in the first try, and maybe some hours later too. But in the second day, no connection, no data collected. All these modems are in remote locations (no easy access), and I am a newbie, as I said, so, I did not connected in these modems via terminal, and did not run any AT command to make checks.
Anybody may understand what can be ocurring?
Strange that 2 works gracefully out of box, and 2 not.
I attach 2 images about the modem and the type of setup I have.
Thanks by taking care.
