HEllo
I request your help because I would like to connect a gsm modem (RS232 connection/AT command) with a CR200 datalogger...
Is it possible to connect my modem on your RS232 port?
And in this case how I can connect to my datalogger if this port is used for the transmission... because there is only one RS232 port....
Finaly my last question...with a CR1000 I can use
serialin and serialout operation to manage my modem (without any problem), I am not sure it is possible on my CR200...
Thanks your for your help!!!
Best Regards
Pascal.
You will need to use a null modem cable between the modem and the CR200. Also set the modem to use 9600 baud and ignore DTR.
The CR200 has a Print() instruction which will output a string out its RS232 port.
Unlike the CR1000, the CR200 does not have a way to check the responses to the AT commands. You will need a delay depending on your modem after sending the AT commands before you can send data.
Hello,
Yes you are perfectly right :)
I found this command (print) on the manual of CR200...
Dear All,
I am working on Siemen TC35i with the data logger of Campbell Sientific (CR200).
Before, I tested them and they worked ok.
But yesterday, I replaced new SIMS and reset the modems and now they do not worked ok.
I think that I do not have full settings.
I would like to ask you about Modem Initialization string for TC35i. and necessary configure for TC35i with Ignored DTR.
Thanks
