The PLMN code can be set only when the DTU is connected locally to a PC using the
DTU Configuration
Tool.
To set the PLMN code for your device:
1. Ask your service provider for the PLMN code for the NB-IoT network.
2. Install the PLMN code into the DTU module. In the
DTU Configuration Tool
, on the
System
tab,
enter the PLMN in the
Operator name
line.
Backup battery power supply
NB-IoT DTU22x data loggers are supplied with or without a built-in power supply unit (depending on the
model, see
). Therefore, the devices can be powered both from an external 7-30 VDC
source and from the 100-240 VAC network through a two-contact terminal block.
Additionally, data logger is equipped with a built-in Li-SOCL2 ER18505 (3.6V, 3500 mAh) battery, which
when external power is disconnected, ensures full operation of the data logger in an autonomous mode
(GPRS - up to 4 years, NB-IoT - from 4 to 10 years).
Backup battery is replaceable. By default, the battery is in transport mode, that is, it is turned off (the
BAT
switch is in the
OFF
position). To activate the ability to switch the data logger to the stand-alone mode
when the external power is turned off, turn the switch to the
ON
mode.
