PDS-220Fx Series User Manual (V1.2, Apr. 2015) 6
1. Introduction
The PDS-220Fx series is a family of Programmable Device Servers, also known as
"Serial-to-Ethernet gateway”, that are designed for adding optical fiber connectivity to RS-
232/422/485 devices.
The user-friendly VxComm Driver/Utility allows users to easily turn the built-in COM ports
of the PDS-220Fx series into standard COM ports on a PC. By virtue of its protocol
independence, a small-core OS and high flexibility, the PDS-220Fx series is able to meet
the demands of every network-enabled application.
The PDS-220Fx series includes a powerful and reliable Xserver programming structure
that allows you to design your robust Ethernet applications in one day. The built-in, high-
performance MiniOS7 boots the PDS-220Fx up in just one second and gives you fastest
responses.
The PDS-220Fx is equipped with 1 RS-232 port and 1 RS-485/422 port. The removable
on-board terminal block connector is designed for easy and robust wiring in industrial
situations.

1.1 Why Fiber Optic Solutions?
The fiber-optic communications permits transmission over longer distances than other
forms of communications because of the signals travel along them with less loss and no
crosstalk. It has following important features: Immunity to electromagnetic interference
(EMI) —Motors, relays, welders and other industrial equipment generate a tremendous
amount of electrical noise that can cause major problems with copper cabling.
High electrical resistance, making it safe to use near high-voltage equipment or
between areas with different earth potentials.
No sparks —important in flammable or explosive gas environments.
Not electromagnetically radiating, and difficult to tap without disrupting the signal —
important in high-security environments.
Because of these reasons, optical fibers have largely replaced copper wire
communications in core networks in the developed world.
Because of these reasons, optical fibers have largely replaced copper wire
communications in core networks in the developed world.

1.2 Why VxComm Technology?
In general, writing a TCP/IP program is more difficult than a COM port program, or the
COM port communication system was built many years ago.
As a result, a new technology, VxComm was developed to virtualize the COM ports of
the PDS to allow up to 256 COM Ports to be used on the central computer. The
VxComm driver saves time when accessing serial devices through the Ethernet without
the need for reprogramming the COM port software on the PC.

PDS-220Fx Series User Manual (V1.2, Apr. 2015) 9
The VxComm driver controls all the details of the Ethernet TCP/IP programming technique;
your COM port program will be able to access your serial devices through Ethernet in the
same way as through COM port with the assistance of PDS-220Fx and VxComm
technology.

1.3 Why Web Server Technology?
Web server technology enables configuration of the PDS-220Fx series via a standard web
browser interface, e.g. Internet Explorer, FireFox or Mozilla, etc. This means that it is easy
to check the configuration of the PDS-220Fx series via an Ethernet network without
needing to install any other software tools; thereby reducing the user’s learning carve.

2. Typical Applications for the PDS
2.1 RS-232/485/422 Device Networking
--- Using Virtual COM Technology ---
The PDS-220Fx series is designed to link RS-232/485/422 devices to an Ethernet network.
The VxComm utility allows the built-in PDS-220Fx COM Port to be virtualized to a
standard COM Port of the host PC as shown below:
In the configuration above, Meter-1 is virtualized to link to COM3 of the host PC. Therefore
a program original designed for the MS-COMM standard can access the meter without
any modification.
COM1/2 of the PDS-
220Fx is mapped to
COM3/4 of the host PC
The original COM1/2
of the host PC
COM1/2 of the PDS-
220Fx is mapped to
COM5/6 of the host PC

2.2 Fiber I/O Applications
The PDS-220Fx series provides fiber optic I/O solution:
Linking to I-7000 series modules
The I-7000 series provides a variety of I/O operations, such as D/I, D/O, A/D, D/A, Counter
and Frequency Measurement, etc. The I-7000 series was originally designed to be used
with RS-485 networks, so COM2 on the PDS-220Fx can be used to link to I-7000 series
modules. They are very robust and work well under the harsh industrial environments.
By using VxComm technology, programs that on the host PC support serial devices can
be upgraded from a RS-485 network to a fiber optic network without requiring any
modifications to the program. Refer to Sec. 2.1 for more information.
2.3 Configurable Fiber Optic Data Logger
Using the VxComm driver, PDS-220Fx + I-7000 modules can be virtualized to become
COM Port + I-7000 modules located on the host-PC, and then the Data Logger in the
DCON Utility can be used to access data of I-7000 from the fiber optic. Signal data
originating from the I-7000 modules can be analyzed using MS-Excel without the need to
write any custom programs
1: The DCON utility includes a log function, as show below:

2: Configure the system connection as shown below and click the “Start” button to begin
logging data.
3: Open the log file in Excel to read the log data as shown in the example below:

By using the I-7000 DCON utility and MS Excel in conjunction with the VxComm
technology, the signal data of I-7000 modules from the fiber optic network can be
analyzed without the need to write custom programs. For more information about the log
function refer to the online help feature (English and Traditional Chinese) of the DCON
utility.
