Overview
The
wienet SDS
is an entry-level industrial Ethernet serial device server which acts as a gateway for
communications between Ethernet (TCP/UDP) port and one or two RS-232/RS-422/RS-485 ports. It is
a compact and field-mount device with software-selectable serial port. The information conveyed
by the
wienet SDS
is transparent to both host computers (Ethernet) and serial devices (RS-232/RS-
422/RS-485). Data coming from the Ethernet port is sent to the designated RS-232/RS-422/RS-485
port, and data received from RS-232/RS-422/RS-485 port is sent to the Ethernet port, allowing full-
duplex and bi-directional communication. In the computer-aided manufacturing or industrial auto-
mation areas, field devices can directly connect to an Ethernet network via the
wienet SDS
. In nor-
mal PCs or laptops, a virtual COM port can be created using our virtual COM software to fetch serial
data from the
wienet SDS
remotely over Ethernet.
With the
wienet SDS
model, it is possible to communicate with a remote serial device over the LAN or
even over the Internet, which dramatically increases reachability and scalability.
Figure 1 illustrates an example of multiple devices connected to the Industrial Serial Device Server. A
PC connects to the Industrial Serial Device Server via Ethernet interface, and a monitored device re-
ports to Industrial Serial Device Server via RS-232/RS-422/RS-485 interface. It is possible to have
multiple PCs connected into the same Industrial Serial Device Server through TCP or UDP transport
protocols, as well as multiple monitored devices connected via RS-232/RS-422/RS-485 to Industrial
Serial Device Server.
