Hello,
we are having difficulties connecting EL005 logger to EnviroMon software through two GSM modems. Modems are working and connection is established at 9600bps. This was checked with Hyper terminal.
We are also able to establish connection through EnviroMon software. However when data should be read from logger, message dialog Logger not found COM1 TELxxxxxx appears on screen.
If I go to options and check Diagnostics, first message appear connection established succesfull and ther Loger version retrieve failed or even program will crash

If logger is connected directly to PC everything is working perfectly.

Many thanks for answer

Hello Erazem,

Have you enabled GSM support in the EnviroMon software?

YOu will need to set the software to communicate via telephone + Modem.

Please let me know how you get on.

Best regards,
Michael

Hi Michael,
yes we have enabled telephone+modem option. And As I indicated in my first post, first we get a message connection established. However, when data should be transmited from logger to PC, we get message Logger not found.
If I listen at serial port, between logger and GSM modem. I see that GSM modem receives two rings then it wrote message CONNECT 9600BPS.

Hope this helps

Hello,

We are running into difficulty here as we do not support GSM modems, we can only offer support with the software.

Firstly start by sending me your logger setup files. These are the envimon.ini and the emwevent.log files. Next, please tell us the Modem setup you are using and the GSM model numbers.

We will work from there.

Regards,
Michael

Hi,
to which address should I send requested files. My email is
erazem_dot_polutnik_at_fs_dot_uni-lj_dot_si.
I doubt there is problem in modems as I'm able to connect two computers with these modems and transfer a file in both directions.
Also EnviroMon indicates connection is established.

Many thanks for your assistance

Hi Michael,
would you be so kind and tell me, which lines are active on serial interface on EL005 logger. Are there only RX/TX and GND needed (pin 2,3,5) or should be other signals connected as well.

Many thanks

Hi

Thank you for your post.

Only TX and RX are needed as data lines. The product takes external power so the voltage lines are not important however having pin 5 as GND is still a good idea. TX is pin 3 and RX is pin 2.
