Encapsulated Serial Network
The RadioLinx RLX-FHES contains its own TCP/IP protocol stack that is
configured with a local area network IP address. A TCP connection is established
between a host client and the serial server creating a socket interface. An
encapsulated ASCII Ethernet packet are delivered to the socket where the serial
sever extracts the serial data stream from the Ethernet packets and outputs it to
the RS-232 serial port. Bi-directional serial communication is supported by
encapsulating the RS-232 port input stream into Ethernet packets, then sending
them to the host client via the established socket interface.
Legacy serial-only HMI software may continue to be used with Ethernet by
installing a third-party COM port redirection driver on the host computer. The
redirection driver provides the client services to establish and maintain a TCP
socket connection with the serial server while simulating a PC COM port to the
HMI application.
Serial Server Network
The
Serial Server Network
can incorporate different configurations of Ethernet.
Any or all the following Ethernet Networks could be used:
Modbus TCP/IP Network (page 24)
Encapsulated Serial Network (page 25)
RadioLinx RLX-FHES industrial radio communicates with legacy serial devices
as well as allowing remote configuration of the radio. The RLX-FHES radio
contains a serial device server that establishes a transparent connection
between a serial device and an Ethernet host. The RLX-FHES radio processes
data on its serial port, and redirects the data through the radio's Ethernet card.
