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.

1.2 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.

1.3 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-
220Fx Series 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.
The VxComm driver controls all the details of the Ethernet TCP/IP programming technique,
meaning that, with the assistance of PDS-220Fx and VxComm technology, your COM Port program
will be able to access your serial devices through the Ethernet in the same way as through a COM
Port.

1.4 Web Server Technology
Web server technology enables the PDS-220Fx Series to be configured via a standard web browser
interface, e.g. Google Chrome, Internet Explorer, or Firefox, 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 learning curve required for maintaining the device.

6. DC Power Input Connector
The definition for “PWR”and “P.GND” for use as the power
supply applies to PDS-220Fx Series.
The valid power voltage range is from +12 to +48 VDC.
The definition for “F.G.” (Frame Ground):
Electronic circuits are constantly vulnerable to Electrostatic
Discharge (ESD), which becomes worse in a continental
climate area. PDS-220Fx Series feature a new design for the
frame ground, which provides a path that bypasses ESD, resulting in an enhanced ESD protection
capability and ensuring that the module is more reliable. It is recommended that the Frame Ground
of the PDS-220Fx series module is corrected to the earth ground, such as the ground of an AC
power supply, to provide better ESD protection for the module.
7. SW1 (Init and Flash Lock Switch)
Init Switch
Init Mode: Uses factory settings and allows the firmware to be updated
Run Mode: Firmware operation mode
For PDS-220Fx Series, the operating mode switch is set to the “Run”position by default. In order to
update the firmware for the PDS-220Fx Series, the switch must be moved from the “Run”position
to the “Init”position. The switch must be returned to the Run position after the update is complete.
Note that the PDS-220Fx must be rebootedafter changing the operating mode.
Factory Default is Run Mode Init Mode

Programmable Serial-to-Fiber Device Server
PDS-220Fx Series User Manual Version 1.3, Oct. 2018 - 17 -
Flash Lock Switch
In factory default settings, the “Flash Lock”function is disabled. User can modify the program by
yourself or update the firmware. But if need to avoid writing or erasing any file in the flash, user
have to enable the “Flash Lock”function in the PDS-220Fx Series. Please switch the position to
“Flash LOCK” and then the PDS-220Fx Series can restrict any write to flash memory.
Factory Default is Non-Lock Flash Lock
