Function Structure of 2 serial ports serial to Ethernet servers USR-N520

Function Structure

serial rs232 to ethernet converter/485 to ethernet/converter serial to ethernet USR-N520:TCP Server

Work mode

TCP Server

Serial to Ethernet servers USR-N520 listens on the setting port
and waits for a TCP client connection.
The data which the serial ports sent out transparently
transmit to all connected TCP clients via USR-N520.

TCP client mode

Serial to Ethernet servers USR-N520 initiates a TCP connection to the set IP address.
If the connection fails, USR-N520 will keep trying to reconnect until it succeeds.
Once the connection is successful, the data will be transparently
transmitted between PC and serial device in bi-directional.

work mode of serial rs232 to ethernet converter/485 to ethernet/converter serial to ethernet  USR-N520:TCP Client

UDP mode

Serial to Ethernet servers USR-N520 will transmit serial data from serial device to
target network device by UDP connection.
USR-N520 will listen to port and transmit all received data to serial device.
