The ESport-10x connects RS232/422/485 serial devices to an Ethernet LAN/WAN providing a reliable communication connection. The ESport-10x Windows driver installs virtual COM ports in the Device Manager of the operating system. The virtual COM port is designed to establish a connection with the ESport-10x. This in turn will allow communications with the connected serial device in the same manner as a device connected to the COM port in a PC. The LAN becomes transparent to the serial device and the software running on the PC. ESport-10x also offers a Heart Beat feature to insure a reliable communications connection.

ESport-111 Ethernet serial server is identical with ESport-101, but with additional 5 pin terminal block. It is made easy for RS485 connections, which is ideal for traditional industrial applications. ESport-112 Ethernet serial server offers two RS-422/485 ports.

All ESport series can be configured as a TCP Client/Server or UDP. It can operate in three modes: “Direct IP Mode”, “Virtual COM Mode”, and “Paired Mode”.

Direct IP Mode:
Direct IP connections allow applications using TCP/IP or UDP/IP network socket programs to communicate with the asynchronous serial port on the ESport-10x. In this type of application the ESport-10x is configured to TCP or UDP server. The socket program running on the PC establishes a communication connection with the ESport-10x. The raw data is sent directly to and from the serial port.

Virtual COM Mode:
requires the installation of a virtual COM port device driver. In this mode, the ESport-10x must be set to either TCP/server or UDP/server in the menu with a designated communication port number. The virtual COM driver is a TCP or UDP client. Once the connection is made, the LAN is transparent to the serial device. Applications work just as if the serial device is connected a host’s physical COM port. The virtual COM port converts the application’s data into IP packet destined for the ESport-10x, which in turn converts the IP packet back to serial data.

Paired Mode:
is also known as serial tunneling. When this type of configuration is selected, no additional software is needed to install in a host PC. In fact a PC is not required to make the connection. Any two dumb serial devices that can communicate with each other through a serial link will be able to communicate using two ESport-10xs and the LAN. Two ESport-10xs are configured with one setup as a TCP or UDP client and the other to TCP/UDP server. When setting up the Server, the Remote IP address section must contain the address of the Client. This will allow the Client’s IP address to pass the IP address-filtering feature of the Server. Conversely, the Remote IP address of the Client must contain the Server’s IP address.

Heart Beat:
The ESport-10x provides a convenient way to establish reliable communications between two devices. Communication port 5300 is reserved for the Heartbeat Protocol. If a loss connection occurs the Heart Beat feature will try to reconnect the TCP data connection every 5 seconds until communications is established again.
