Industrial LTE Terminal – RS485

Industrial, certified communication terminal enabling data transmission from any devices equipped with an RS485 interface using a standard LTE cellular network. SPIDER 485 is a reliable device built on the basis of high-class components, including a certified AC/DC 100-277V power supply that allows direct connection to a low voltage AC network.

The integrated cellular module enables transmission in LTE CAT1 networks both in commercial bands and in the 450 MHz band, i.e. B31 or B72. In turn, the housing of the device, which allows sealing of electrical interfaces, is used by many energy distributors (DSOs) throughout Europe.

The built-in TCP/IP stack allows the transmission of any application protocols, i.e. MODBUS, IEC, DLMS/COSEM and others in a transparent mode, thanks to which SPIDER 485 allows you to connect any devices with any application protocol to the Internet network. Such devices can be energy meters, PV inverters, industrial controllers or end sensors.

The dedicated PMConnect application and the built-in LightweightM2M (LwM2M) protocol client allow for simple and standardized management and configuration of the device both locally and remotely. Thanks to LwM2M, the SPIDER 485 modem can be managed by any LwM2M server compliant with this standard.
