All Site-Log
series data loggers come with an USB and an AUX ports. The USB port is
for connecting directly to the computer. The AUX port is
for connecting to a serial communication device like a Modem or an embedded
Device Server when the logger needs to be accessed remotely.
Please make sure SiteView and USB driver are installed correctly. Refer to Install
SiteView and USB driver for details on the installation.
USB Port Connection
Start Communication:
- Connect accompanied USB cable from the logger to a computer's USB port.
SiteView
application starts running and the logger icon is
showing in the USB tab page of the communication
panel:
Adjust USB Settings:
Each time when
you selected a USB icon under USB Port list, the settings for that port will
be displayed under the properties section. You may change the settings based on
the communication quality. For detailed explanation of each setting please refer
to Communication Panel.
Serial Port Connection
Start Communication:
- Launch SiteView
application by double clicking on SiteView icon on the
desktop:
SiteView application starts running. Click “Serial Port” tab in the
communication panel,
Adjust Serial Port Settings:
Each time when you selected a COM port icon under
Serial
Port list, the settings for
that port will be displayed under the
properties section. You may change the settings based on the
communication quality. For detailed explanation of each setting please refer
to Communication
Panel.
Ethernet Connection
Start Communication:
The Device Server was pre-configured with the correct
parameters. You can use Link Local and multicast
DNS (also known as Bonjour) to locate the Device Server and its IP address.
Bonjour Browser can be
downloaded from our website at: www.microedgeinstruments.com/resourcedownload
Once you run Bonjour Browser
and select Web Server(HTTP) you will see a window similar to the
following:
Write down the IP address
besides the SitePlayer Telnet.
SiteView
application starts running. Click “Ethernet” tab in
the communication panel.
In the following pop-up dialog, enter the
IP address that you obtained from the preceding step. Give a meaningful
description of the connection and click “OK” button to close the
dialog.
Notice a new connection icon was
added to the list.
If you use other
brand Device Server you may need to adjust Port and Packet Size values accordingly in order to make a
successful connection.
Adjust Ethernet
Settings:
Each time when you selected a Ethernet icon under IP Address list,
the settings for that address will be displayed under the properties section. You may change
the settings based on the communication quality. For detailed explanation of
each setting please refer to Communication
Panel.
Modem Connection
When you use Modem to communicate with a logger, you
need one local Modem to connect to the computer where SiteView is running, and
another remote Modem to connect to the
logger.
The following figure
illustrates the correct connection between a computer and a logger.
The
Modem settings are under the Serial Port connection:
In order
to make the connection, both local and remote Modems must be initialized
correctly.
If the remote Modem has not been initialized by SiteView, the Modem
needs to be initialized. The default initialization string that works with US
Robotics is:
AT&F&D0&K0&Q0\N1%C0S0=1S37=9M0&M0-V90=0E0&W
To initialize
a remote Modem:
-
Change the Initialization
String.
-
Choose the correct COM port
that is connected to the
Modem.
-
Click Initialize
MODEM button.6
-
You should get the
confirmation dialog if the initialization was
successful.
The
following table explains each command in Default Initialization

NOTE:
Different Modem may have different AT commands. The default initialization

Commands for detai
The local Modem gets initialized before SiteView
tries to dial the number for the Modem connection.
The default
initialization string that works with US Robotics 32K Modem
is:
AT&F &D0 &K0 &Q0 \N1 %C0 S37=13
E0 &W
The default initialization string is located under
each COM port bar:
You may change
the string based on the Modem you are using.
To communicate with the logger via
Modem:
-
Connect both Modems
correctly.
-
Go to COM Port page and highlight the COM port
that is connected to the local Modem.
-
Make sure Is Modem check box is checked. Make sure Phone
No. text-box has the valid phone number the remote Modem is connected.
Make sure Modem Initialization is
correct.
-
Double click the COM port icon to start the communication. If the
communication is successful the logger's status page will appear.
