You can use the VPN technology of OpenVPN for the secure transfer of data via the mobile
wireless connection of the CMR. A VPN tunnel is established between the CMR and the
connection partner (mobile phone/tablet, PC). In this case the CMR is the OpenVPN server,
the partner (mobile phone, PC) is the OpenVPN client.
In addition to this you can use OpenVPN for direct communication with the BM if the CMR is
entered as a router with the BM.
The CMR RTU uses OpenVPN version V2.3.11.

see section OpenVPN-PSK (Page 98).
●
To use DynDNS, apart from the requirements listed above (SIM card, data contract,
mobile wireless network) you also require the following:
– A suitable service provider
– A public IP address
– Note the section "Time of day" below.
●
– For HTTPS via mobile wireless you require a public IP address for the CMR.
– Note the section "Time of day" below.
●
When you use certificates, for example when you use HTTPS, e-mail (secure) or
DynDNS, you require the precise time of day and the precise date for checking the
certificates.
Only use antennas from the accessories program for the CMR. For more information, refer to
the section Antennas (Page 155).
● Mobile wireless
To operate the CMR, you require an antenna that is adapted to the standard of the

1.3 Requirements for use
You require a SIM card of your mobile wireless provider.
Note the following recommendations for the mobile wireless contract or for the SIM card:
● Where possible sign a mobile wireless contract with a provider that makes all required
functions available. Should
For example to use DynDNS a public IP address is required.
To send SMS messages, the SIM card must be enabled this function and have a phone
number.
● Avoid using a multi SIM card. This can lead to errors in time-of-day synchronization.
● Where possible sign a fixed mobile wireless contract and do not use prepaid cards.
A flat rate for SMS and data can be recommended.
If, however, you want to use a prepaid card note the following:
– If your credit has been used up, the CMR does not send an automatic warning.
– You can query your current credit with your provider.
● With the CMR2040 for faster data traffic a contract (with corresponding SIM card) is
recommended that supports the mobile wireless standard LTE.
The CMR2040 however also supports UMTS.
● Where possible, use a standard SIM card without an adapter.
● The provider often assigns a PIN (Personal Identification Number) for the SIM card.
SIM cards that are only used for the data services (see above) can be almost always
used without a PIN. You do not need to assign a PIN in the configuration of the CMR.
● The following access data for the mobile wireless network must be present:
– Access Point Name (APN)
– Depending on the service provider also name and password for the APN
– The authentication method
For more information, refer to the section Mobile wireless settings (Page 87).
The card receptacle of the CMR for the SIM card is compatible with the following card
formats:
● Mini SIM card, 25 x 15 mm (ISO/IEC 7810 ID-000)
● Micro SIM card, 15 x 12 mm (ETSI TS 102 221 V9.0.0) if an adapter exists.
● Nano SIM card, 12.3 x 8.8 mm (ETSI TS 102 221, TS 102 221 V11.0.0) if an adapter
exists.
