Telemetry Gateway A850 User Manual
DynDNS Service (Dynamic Domain Name System)
Manages the host name in the DNS so that the gateway can be accessed on the
internet. This is important if your internet provider only provides dynamic IP
addresses, i.e. IP addresses that can change every time the system accesses
the internet.
Note
Note that for GPRS connections a static public IP address is required.
Dynamic DNS allows you to assign a fixed host name to a dynamic IP address
and to access this address via the host name.
SSH Tunnel Service (Secure Shell Tunnel)
Manages the secure shell tunnel to connect end devices via the internet with
secure communication.
SSH tunneling makes it possible to connect other hosts on the internet to the
A850 Telemetry Gateway using an SSH server as a proxy even if the A850
Telemetry Gateway does not have an official IP address or cannot be accessed
directly from the internet.
Notification Service
Manages notifications. The notifications are placed in a queue and sent to the
notification server. Different notifications are generated:
•
•
•
Note
To send notifications as text messages (SMS), an external GSM modem must be
connected.
NTP Service (Network Time Protocol)
Manages the protocol for synchronizing the time between computers and
devices.
Sensor Types
The Sensor Types tab provides additional information about the sensors on the
network.
The following tabs are available:
•

•
You can add new sensors, delete sensors and copy or export entries.

Notification from the gateway (depending on the enabled events such as
data delay, restart, configuration changes).
