Description

Package:
USR-DR404 *1 PCS
Antenna* 1 PCS
Power Supply *1 PCS

USR-DR404 supports serial port to WIFI function, make the serial port (RS485)connection switch intoTCP/IPnetinterface to realize the bi-direction transparent transmission between serial port and WIFI/Ethernet.
Enableserial devicesto have TCP / IP network interface function immediately, connect to the network for data communication, greatlyextendthe communication distance of serial devices
