The following step is only necessary if you are using an external supply or charging voltage.
11. Now switch on the external supply or charging voltage.
Note: If you are using a power supply unit without an integrated energy store, the external supply or
charging voltage must be switched on before the optional step during which the connection to the server
is tested.
7.5.1.1 Connection examples
Connection examples
1 Main terminal block of the
myDatalogEASY IoTmini 4 2-wire mA sensor
2 Isolated relay contact 5 3-wire mA sensor or 3-wire U-sensor
3 Sensor with open collector output
Note: The "Counter", "Frequency" and "PWM" operating modes require a permanent supply of the
sensors. One of the two switchable sensor supplies must be permanently active for this purpose. The
use of VEXT is recommended for this purpose (see sensor 1 in the connection example above). The
power consumption per input when the switch contact is closed can be up to 384µA due to the load of
10k086 .
7.5.2 Connecting the LoRa antenna
Important note: To ensure the correct functionality, only use antennas that are supplied by the
manufacturer.
The standard antenna (Antenna LoRa FME -F, 301004) is attached directly to the antenna connector (see
"Overview" on page 20) of the myDatalogEASY IoTmini .
If the distance between the antenna position and the myDatalogEASY IoTmini is too great, you can use a 5m
Extension cable for antenna FME-F/FME-M 5m (206.805).
1. Ensure that the myDatalogEASY IoTmini is de-energised.
2. If you need an antenna extension, connect it to the antenna first.
