Using with Campbell Scientific Dataloggers
briefly every 2-3 seconds. When the LED starts to flash it indicates that the
modem has signed onto the phone network successfully. Note the frequency
of flashing will vary with the depending on the power state of the modem and
whether data is being transferred.
6.
Start-up your PC and run PC400, Loggernet or your chosen communications
program. Set up a phone or TAPI connection to the datalogger, following the
instructions for your software package to do this. Enter the data phone
number assigned to your SIM as the phone number of the datalogger to be
called.
7.
Apply the setup setting and then connect to the datalogger. You should find
the PC connects to the datalogger and the displayed datalogger time then
starts to update showing you have a working system. If this does not happen
please read the rest of this manual in more detail.
3. Quick Start Guide – for GPRS communications
The COM110 modem can also be used for GPRS communications. The COM110
will support dataloggers that run their own TCP/IP software, e.g. the CR800,
CR1000 and CR3000 loggers or it can be used running TCP/IP functions built into
the modem which will give basic communication over GPRS for other loggers,
e.g. the CR200X.
This quick start section only covers systems which have a SIM card with a fixed IP
address. Other configurations are detailed elsewhere in this manual.
1.
Make sure you have a data enabled SIM with the security PIN disabled and
enabled for GPRS use. To insert the SIM card eject the card tray from the
end of the modem by pushing in the button with a small screwdriver or pen.
Put the SIM card in the small card tray taking care the angled corner of the
card matches the moulding in the tray. The gold plated contacts of the card
should be uppermost and remain so when the card tray is pushed back into
the modem.
2.
Now the modem and logger should be setup using the Mobile Data Assistant
package. To do this you require a modem programming cable (a grey 9 to 15
way serial cable), plus an optional USB-Serial convertor, a cable to allow
communication with the datalogger and a power supply to power the modem
and logger.
3.
Install the Mobile Data Assistant package and start it running. You will be
presented with a screen like that shown below.
