tcp client of working mode of DIN-rail RS485 serial to Ethernet converter

Working mode

Serial to Ethernet converter USR-DR302 will initiate TCP connection to the destination IP address
that configured by the user and serial to Ethernet converter will continuously try to reconnect
if establishing TCP connection unsuccessfully.

tcp server, DIN-rail RS485 serial to Ethernet converter

Serial to Ethernet converter USR-DR302 monitors the set port and waits
for a TCP client connection. Data from the serial device will transmit
to all successfully-connected via serial to Ethernet converter.

UDP Client, DIN-rail RS485 serial to Ethernet converter

USR-DR302 only communicates with the target interface of the target IP,
thus to assure the accuracy of data transmission.

UDP Server, DIN-rail RS485 serial to Ethernet converter

DR302 can transmit the data automatically to the last time transferred
device after receiving the data, which is suitable for multi-network
devices that need to communicate with the DR302.

httpsD Client, DIN-rail RS485 serial to Ethernet converter

DR302 supports the function of transmitting the serial data to the
specified server in the form of httpsD (GET/POST).

DIN-rail RS485 serial to Ethernet converter supports modbus gateway

Support Modbus gateway
