Communication one to many using TCP
IP address:port = Com X
IP address:port = Com Y
IP address:port = Com Z
Virtual IP
Description
Many legacy software applications do not have any facilities to directly use Ethernet but there is
a requirement to use a newly installed or existing LAN to communication to many serial devices.
This prblem is solved by installing Comms redirection software on the host PC. The redirection
software works by creating virtual comms ports on the computer. The Virtual comms port can be
selected and use in the same way as a hardware based port. The Comms redirection software will
encapsulate the serial data in a TCP/IP and send it to the relevant EDW-120 device. The EDW-120
will then strip off the TCP/IP frame and just forward the serial data to the target device. In the
reverse direction the EDW-120 will encapsulate the data and the comms redirection software will
strip off the TCP/IP frame. Together with the product Virtual IP is delivered, this software enables
connection of 255 COM ports to virtual IP addresses.
