ION 7500 / ION 7600 User’s Guide Setting Up the Network for the MeterM@il Feature
MeterM@il Internal Email Server Feature Technical Note Page 241
In the illustration below, the SMTP mail server does not reside on the same local
network as the meter, so an SMTP mail server connection may not always be made
quickly. When the meter has an email to send, the following process occurs. First,
the meter contacts the dial-on-demand router that contains an internal modem.
Second, the router modem contacts the Internet Service Provider (ISP) modem to
connect to the Internet and initiate a connection to the specified SMTP mail server.
Connecting to the SMTP mail server can take longer than the SMTP Connection
Timeout register default of 60 seconds. In such a case, the interval should be
extended.
