3.
Connect the modem to the PC using the programming cable (use a
serial to USB convertor if necessary). Connect the modem to a nominal
12V DC supply (the data logger supply can be used if available).
4.
When using the MDA for the first time select the com ports on your PC
to which you intend connecting the data logger and modem you are
going to setup (they can be the same if the devices are swapped at the
appropriate steps in the process). Also set the baud rate, which would
normally be 115200, except for the CR200X and older loggers which
communicate at 9600 baud. If you are connecting to a data logger via
it’s built in USB port the logger will need to be powered on and
connected to the PC for it to appear in the COM port list.
5.
Now select the “Setup modem” option, then select the data logger you
are going to use, then the modem type (select COM111). You will
then be prompted if you want to make a GSM (dial-up) or GPRS/2G/3G
(data) connection, select the latter. Then you will be asked for the type
of IP connection. For the CR300, CR6, CR800, CR1000 and CR3000
select “Logger IP Stack”(this indicates you will use the TCP/IP
functionality built into the logger operating system, often known as a
“software stack”).
6.
Now select the method of connection control – select “Logger
Listening”, for the CR200X and older loggers select “Modem
Listening” option.
7.
At this point you will be asked for detail of the connection you are
going to use with this screen:
This screen varies with logger type. A data logger port option will be
shown if different connections are possible so you can select the port on
the logger the COM111 will be connected to using the drop down
option list. Select RS232 for a direct connection to the RS232 serial
port on the logger or one of the CS I/O SDC options to match the
configuration of an SC105 if used, normally set to SDC7. Other options
