E840-DTU(NB-02)

[Antenna Interface]:SMA-K

[Size]:84*82*25mm

[Interface]:RS232/RS485

[Weight]:133±5g

[Introduction]:E840-DTU(NB-02) can realize the communication between serial port device and network server via NB network. With simple AT command, users can easily use this product to achieve bidirectional transparent data transmission from the serial port to the network. The transparent transmission is between UART devices(referring to PC) and net sever (replaced by TCP testing tools).
