Appendix B. Configuring the Raven XT
Modem for PPP
The Raven XT’s template file configures the Raven XT to function as a
serial server. As a serial server, the modem has an IP address, and port
number 3001 for the Raven XT’s RS232 port.
LoggerNet sends data via TCP/IP over the internet to the datalogger. The
modem removes the data from the TCP packet and sends the data out the
RS232 port to the datalogger. Returning data is put into a TCP packet by
the modem and sent back to LoggerNet.
Settings in the Raven XT and datalogger (CR800, CR1000, and CR3000),
can be changed to configure the RS232 serial ports for Point-‐to-‐Point
(PPP) protocol. When configured as PPP, the Raven XT functions as a
router, routing TCP/IP communications to the IP stack of the datalogger.
PPP enables the datalogger to send/receive messages via email, HTTP, FTP
to and from the datalogger, and allows concurrent communications
between networked dataloggers and LoggerNet.
The default datalogger port number for PakBus/TCP communications is
6785. The datalogger will also respond to port 80 for HTTP, 23 for Telnet,
and 21 for FTP. These ports can be disabled in the dataloggers
configuration.
After the RS232 port on the modem has been configured as
PPP, use AceManager with a TCP or UDP connection to
establish communications with the modem. It may also be
possible to connect with the modem through its RS232 port
using the “SOS” mode.
Raven XT Settings for PPP Mode:
Download the current Raven XT AceManager template file from
http://www.campbellsci.ca/download
Load the template into
AceManager and make the following changes in steps 1 and 2 before
writing them to the Raven XT modem.
Use AceManager to configure the following UDP setting:
•
MD = 02-‐PPP
