\"Basic<\/p>\n

Basic Function of\u00a0DIN-Rail RS485 to Ethernet Converter USR-DR302<\/h3>\n

Realize bidirectional transparent transmission
\nbetween RS485 and Ethernet<\/p>\n<\/div>\n

\"<\/p>\n

DIN-Rail mounted RS485 to Ethernet Converter<\/h3>\n

Small size, easy to manage and maintain, cost-effective<\/p>\n<\/div>\n

\"Function<\/p>\n

Function Diagram<\/h3>\n<\/div>\n
\"tcp<\/p>\n

Working mode<\/h3>\n

Serial to Ethernet converter USR-DR302 will initiate TCP connection to the destination IP address
\nthat configured by the user and serial to Ethernet converter will continuously try to reconnect
\nif establishing TCP connection unsuccessfully.<\/p>\n<\/div>\n

\"tcp<\/p>\n

Serial to Ethernet converter USR-DR302 monitors the set port and waits
\nfor a TCP client connection. Data from the serial device will transmit
\nto all successfully-connected via serial to Ethernet converter.<\/p>\n<\/div>\n

\"UDP<\/p>\n

USR-DR302 only communicates with the target interface of the target IP,
\nthus to assure the accuracy of data transmission.<\/p>\n<\/div>\n

\"UDP<\/p>\n

DR302 can transmit the data automatically to the last time transferred
\ndevice after receiving the data, which is suitable for multi-network
\ndevices that need to communicate with the DR302.<\/p>\n<\/div>\n

\"httpsD<\/p>\n

DR302 supports the function of transmitting the serial data to the
\nspecified server in the form of httpsD (GET\/POST).<\/p>\n<\/div>\n

\"DIN-Rail<\/p>\n

Support Modbus gateway<\/h3>\n<\/div>\n
\"more<\/p>\n

More functions<\/h3>\n

Virtual serial software<\/h3>\n

Solve the problem of PC software
\nas a serial port can not communicate
\nwith networking device.<\/p>\n

Network Heartbeat Packet<\/h3>\n

Serial server maintains the normal
\nconnection with the server by sending
\nheartbeat packet regularly.<\/p>\n<\/div>\n

\"DIN-Rail<\/p>\n

Identity Heartbeat Packet<\/h3>\n

When 302 works as TCP Client, it can send identity packet
\npacket to TCP server which can be identification.
\nIdentity packet can be IMEI code, ICCID code
\nand user editable identity packet.<\/p>\n

Advanced protection<\/h3>\n

Level 4 anti-static,
\nlevel 3 electrical pulse protection,
\nlevel 2 surge protection<\/p>\n<\/div>\n

\"DIN-Rail<\/p>\n

Product details<\/h3>\n

PC+ABSC material, portable, low cost, V0 flame retardant,
\nensure the safety of the product.<\/p>\n<\/div>\n

\"DIN-Rail<\/p>\n

Power data networking transmission<\/h3>\n

Small size which is available for narrow space;
\nDIN-Rail mounting, easy to install on the wall;
\nThe terminal data of the distribution box can quickly convert into the network data,
\nreal-time communication, reduce the cost effectively.<\/p>\n<\/div>\n

\"DIN-Rail<\/p>\n

Unattended Weighing<\/h3>\n

Connect serial to ethernet converter USR-DR302 to barrier gate and it can realize remote control
\nof barrier gate by Ethernet in control center.<\/p>\n<\/div>\n

\"DIN-Rail<\/p>\n

Traffic Lights Management System<\/h3>\n

Connect serial to Ethernet converter USR-DR302, and it can realize traffic data acquisition and
\nprocessing by Ethernet in the control center. And the control room personnel can quickly
\nmake traffic scheduling and planning according to the site condition.<\/p>\n<\/div>\n<\/div>\n
