02 / CONNECTION
Match the interface.
Then connect the equipment.
Match physical interfaces and application protocols separately.
Field interfaces
A / B are RS-485; V− / V+ are DC 5–24 V power inputs.
For terminal positions, wire assignments and installation, follow the official wiring instructions .
03 / CONFIGURATION
Choose a configuration
that fits your site.
01Choose -C commercial grade, -N wide temperature range or -I industrial grade for the site operating temperature; specify the 16-frequency configuration when ordering.
02Select the LoRaWAN band, cellular module and transmit-power variant for the region; configure transmit power according to local regulations.
03Select this product for indoor installation; enclosure material is not a substitute for its protection rating.
04SIM compatibility does not imply a built-in 5G modem. Cellular technology depends on the installed module; select a compatible module if carrier bands differ.
Refer to the corresponding official documentation and confirmed configuration for exact models, interfaces and options.
