Appendix C. Configuring the Raven for
PPP
The Raven template file configures the Raven to function as a serial server. As
a serial server, the modem has an IP address, and port number (6785) for the
Raven’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 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 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 ACE Manager 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.
NOTE
Raven Settings for PPP Mode:
Download the current Raven EDGE ACE Manager template file from
http://www.campbellsci.ca/download.html
. Load the template into ACE
Manager and make the following changes in steps 1 and 2 before writing them
to the Raven modem.
