The installation process when outbound internet traffic is accepted
The CMe/CMi Series product uses GPRS internet connection to download configuration profiles and set date/time in the installation process. Enabling outbound internet traffic from the closed APN dramatically makes the configuration in field easier.
Setting the APN
Before starting any installation, the product must know which APN to be used. This is not needed when an open APN is used due to the AutoAPN fascility in the CMe/CMi Series product.
Example of setting the product to use static.telenor.se:
qset net static.telenor.se
The product will when initiating an SMS install command do the following operations (default settings):
1. Connect to http://dist.elvaco.se on TCP port 80 and download a configuration (if set in the installation string)
2. Connect to a time server to set product date/time using NTP (UDP port 123) or DayTime protocol (TCP port 13).
3.Search for connected M-Bus slaves
4. Send an SMS report back to the user
5. Send an E-Mail installation report using configured SMTP server (if e-mail recipients are configured).
Step (2) is only executed if the configuration profile parameter is used in the installation sms. Following example will download configuration profile myprofile from Elvaco configuration server:
install 1 myprofile
Changing NTP and DayTime settings
Disable time synchronization in the installation process, execute the following command on the product:
To use another NTP or DayTime server or port, execute the following command(s):
The time server protocol to use (NTP and/or DayTime) can be changed using following command:
E-Mail settings (SMTP)
The SMTP Server can be changed in two ways; Using command qset email or setting the configuration keys manually.
Following example will set to send E-Mails to firstname.lastname@example.org, use SMTP server mysmtp.net on port 2525 with anonymous access using qset email:
qset email email@example.com mysmtp.com 2525
Do you not have any SMTP server you can use, for example Dyn.com with the following settings
qset email firstname.lastname@example.org 184.108.40.206 2525
Firewall settings and DNS settings in the closed APN
DNS server must be provided by the network provider.
Following outbound traffic must be open from the product to the internet to enable full functionality:
TCP PORT 80 to http://dist.elvaco.se (currently 220.127.116.11)
TCP PORT 13 to 18.104.22.168 (DayTime)
UDP PORT 123 to 22.214.171.124 (NTP)
TCP PORT 25(default port) for SMTP traffic for configured SMTP Server (E-Mail)
