5. Overview
The LS300G modem may be configured in one of two ways, depending on the
communications type and needs of the user. For many applications that just
need a connection for data collection and datalogger maintenance or
monitoring, setup as a serial server is sufficient. In this mode, the modem
receives IP communications over the cellular network and converts those to
serial (RS-232) communications to pass on to the datalogger. From the
datalogger’s perspective, this is no different than a serial cable connecting it to
a PC. Section 4 , Quickstart
(p. 2)
, describes setting up the LS300G in serial
server mode.
Alternatively, if IP communications are needed on the datalogger, the modem
may be set up in Point-to-Point Protocol (PPP) mode. In this mode, the modem
simply passes IP communications directly to the datalogger. This enables
features such as FTP, HTTP, and emailing. For information on configuring the
LS300G in PPP mode, see Section 7.5 , AceManager and Template Files
(p. 16)
,
and Section 7.6 , Enabling PPP Mode
(p. 19)
. See Appendix B , EmailSend Using
the Gmail Outgoing SMTP Server
(p. B-1)
, for more information on emailing.
