Using the Raven II CDPD Modem – Canary Systems Application Note #12 – March 2002 – Page 7 of 8
Troubleshooting
Windows includes utility programs that can be used to quickly and effectively troubleshoot the connection
to the Raven II equipped datalogger.
The first is PING, a utility for checking whether a connection is possible to the Raven II. This will also
verify that the service is properly activated and that the modem is configured and responding.
First open a DOS or Command Prompt window.
Type PING, followed by the IP that has been provided by the service provider and has been programmed
into the modem, an example is shown below.
If the connection is not functional you will see timeout errors. Typical response time using the Raven II
modem should be between 500 and 1000 milli-seconds.
The second tool is Hyperterminal, this is a program
designed for terminal emulation sessions.
Hyperterminal is usually found under the
Programs |
Accessories
or
Program | Accessories |
Communications
menus.
When you first start Hyperterminal you will need to
configure a connection to the Raven modem. The first
dialog shown asks for a name for the connection.
Enter a name and select an icon if desired. Press OK.
The second dialog will prompt for Connect to details.
Select
TCP/IP (Winsock)
from the Connect Using
drop-down list. The TCP/IP configuration form will
display. Enter in the appropriate IP and port as shown,
remember to use the IP provided by the service
provider!
Press OK.
