The Data Connect Data
Connect Eport 101 / Eport 102 Ethernet Serial Server connects RS232, RS422, and
RS485 serial devices to an Ethernet LAN/WAN providing a reliable communication
connection. The Data Connect Eport 101 / Eport 102 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 Data Connect Eport 101 /
Eport 102. 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.
The Data Connect Eport 101 / Eport 102 also offers
a Heart Beat feature to insure reliable communications connection. The Data
Connect Eport 101 / Eport 102 can be configured as a TCP Client / Server or UDP.
The E-port 101 operates in “Direct IP Mode”, “Virtual COM Mode”, and “Paired
Mode”. Direct IP connection allows applications using TCP/IP or UDP/IP network
socket programs to communicate with the asynchronous serial port on the Data
Connect Eport 101 / Eport 102. In this type of application the Data Connect
Eport 101 / Eport 102 is configured to TCP or UDP server. The socket program
running on the PC establishes a communication connection with the Data Connect
Eport 101 / Eport 102. The raw data is sent directly to and from the serial
port.
The Virtual COM mode requires the installation of the virtual COM port
device driver. In this mode, the Eport101 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 Data Connect Eport 101 / Eport 102,
which in turn converts the I IP packet back to serial data.
Paired mode is also called serial tunneling. When this type of
configuration is selected, no additional software is needed to install
in the 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 Data Connect Eport 101
/ Eport 102s and the LAN. Two Data Connect Eport 101 / Eport 102s 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.
The Data Connect Eport 101 / Eport 102 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.
Data
Connect Eport 101 / Eport 102 will work at Loop Back Mode, all data is
sent back immediately. This feature makes the connection testing ease.
