PDS-220 Series User Manual (V1.0, Jun.2010) ----- 5

1. Introduction

The PDS-220Fx series is a family of Programmable Device Servers, also known as

"Serial-to-Fiber gateways”, that are designed to enable optical fiber connectivity to be

added 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 rapidly design robust custom Fiber optics applications. The built-in,

high-performance MiniOS7 boots up the PDS-220Fx in just one second and gives you

fastest responses.

1.1. Why Fiber Optic Solutions?

Fiber optic communication permits transmission of data over longer distances than other

forms of communication because the signals travel along the fiber with minimum loss and

no crosstalk. Fiber optics provides the 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 environments that contain flammable or explosive gas.

˙ No electromagnetic radiation, and it is difficult to tap into the signal without causing

disruption, which is an important factor in high-security environments.

Because of these reasons, optical fibers have largely replaced copper wire communications

in core networks in the developed world.

PDS-220 Series User Manual (V1.0, Jun.2010) ----- 7

1.2. Why VxComm Technology?

In general, writing code for a TCP/IP program is more difficult than for a COM port

program, or perhaps 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-220Fx 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 fiber optic

network without the need for reprogramming the COM port software on the PC.

PDS-220 Series User Manual (V1.0, Jun.2010) ----- 8

The VxComm driver controls all the details of the TCP/IP programming and with the

assistance of PDS-220Fx and VxComm technology, your COM port program will be able

to access your serial devices through the fiber optic network in the same way as it would

through a standard COM port.

PDS-220 Series User Manual (V1.0, Jun.2010) ----- 9

1.3. Why Web Server Technology?

Web server technology enables configuration of the PDS-220Fx via a standard web

browser interface, e.g. Google Chrome, Firefox, Internet Explorer or Mozilla, etc. This

means that it is easy to check the configuration of the PDS-220Fx via a fiber optic network

without needing to install any other software tools, thereby reducing the user’s learning

curve.

2. Typical Applications for the PDS-220Fx

2.1. RS-232/485/422 Device Networking

--- Using Virtual COM Technology ---

The PDS-220Fx series is designed to allow RS-232/485/422 devices to be connected to

a fiber optic network. The VxComm utility allows the built-in PDS-220Fx COM port to be

virtualized to a standard COM port on a host PC, as shown below:

In the configuration above, Meter-1 is virtualized to link to COM3 on the host PC.

Therefore a program originally designed for the MS-COMM standard can still access the

meter without the need for any modification to the program.

2.2. Fiber I/O Applications

The PDS 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. These modules are very robust and work well in harsh industrial

environments.

By using VxComm technology, programs on the host PC that 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 from the I-7000 via the fiber optic network.

Signal data originating from the I-7000 modules can be analyzed using MS-Excel without

the need to create any custom programs

1. The DCON utility includes a data logger function, as show below:

PDS-220 Series User Manual (V1.0, Jun.2010) ----- 12

2. Configure the system connection, as shown below, and click the “Start” button to begin

logging data.

3. Open the log file in MS-Excel to read the log data, as shown in the example below:

PDS-220 Series User Manual (V1.0, Jun.2010) ----- 13

By using the I-7000 DCON utility and MS-Excel in conjunction with VxComm

technology, the signal data of I-7000 modules from the fiber optic network can be

analyzed without the need to create any custom programs. For more information about the

log function refer to the online help feature (English and Traditional Chinese) of the

DCON utility.

4. Setting up the PDS-220Fx module

Step 1. Connect the PDS-220Fx module to the fiber optic network

Before connecting the PDS-220Fx module to a fiber optic network, the following

items are needed:

1. Power Supply：12 ~ 48 V

DC

(e.g. DP-665:

http://www.icpdas.com/products/Accessories/power_supply/power_list.htm )

2. Fiber to Ethernet Converter (e.g. NS-200AFT

http://www.icpdas.com/products/Switch/industrial/industrial_list.htm )

3. Check that the network settings on the PC are correctly configured and the Ethernet

connection is functioning normally.

4. Disable or correctly configure the Windows firewall and any Anti-Virus software

firewall first or else the “Search Servers” function in the VxComm Utility may not work

correctly. (Contact your System Administrator for more details if you are unsure how to do

this.)

5. Connect the PDS-220Fx module to the fiber optic network as shown on the following

page and switch on the power.

6. Make sure the LED indicator on the PDS-220Fx is flashing.

7. Install the VxComm Utility on your PC

The software is located at：

CD: \Napdos\7188e\tcp\vxcomm\driver(pc)\

http://ftp.icpdas.com/pub/cd/8000cd/napdos/7188e/tcp/vxcomm/driver(pc)/

PDS-220 Series User Manual (V1.0, Jun.2010) ----- 20

Connect both the NS-200AFx module and your computer to the same sub network or

the same Switch.

Short the RXD and TXD pins on the PDS-220Fx module to execute a self-test.

Supply 24 V

DC

(12 ~ 48 V

DC

) power to the PDS-220Fx module.
