Dear All
i'm trying to connect a com110 with a sc105 to a cr510
i have use mobile data assistant to configure the com110.
when i do a diagnostic the ip address change every 30 second approximatively. and i can't connect to my cr510 with loggernet.
Does anybody have an idea.?
regards
Maybe you need to check, but I am quite sure that the CR510 can only handle GSM connections (CSD Circuit Switched Data), GPRS connection and its associated IP address are useless.
Try to set LoggerNet for calls via phone modem, using the DATA number of remote SIM, usually the DATA number is different from the voice number. You need an analog or GSM modem installed on your PC where run LoggerNet.
The CR510 should be able to do GPRS communications with a COM110 as the COM110 should get configured to act as a terminal server.
I will check how much testing we did with the CR510/SC105 combination and report back.
I cannot confirm this right now but I have a hunch as to what may be wrong. As a quick trial can you connect the SC105 to a PC and configure it manually and set the "RS-232 Mode" to PC/PDA. This should prevent the logger from attempting to hang up the modem every 30 secs if there is no traffic.
Save the new setting and see if the IP is then held for longer. You may then be able to connect with Loggernet as long as you are using network that has public IP addresses or you have a fixed IP address that it routed to the logger.
It has been pointed out to me that the SC105 is not configured by the Mobile Data Assistant package, so if you have not configured it then it will be set to the defaults of 9600 baud and Modem mode. This will work fine for the CSD dial-up mode with the COM110 but as I inferred yesterday, as the logger knows nothing about the GPRS connection, it will timeout the connection after 30 sec of inactivity and due to the handshaking line activity, hang-up the modem. To avoid this set the SC105 to PC/PDA mode and the modem should stay online permanently.
